Part I., page 98. (Dewey, _American Journal of Science and Arts_, 1819,

vol. I., page 340; and 1822, vol. V., page 398.)--Mr. Dewey found, in June, snow 2 meters deep on ice of unknown depth. On his second visit he found less ice and snow than on his first visit, as the trees in the neighborhood had been cut down.

Glacière near Williamstown, Massachusetts.--Described in Part I., page 101.

Freezing Well near Ware, Massachusetts.--(_Geology of Vermont_, 1861, vol. I., page 197.)--Depth 11.5 meters. This is in a sand and gravel formation much like that at Brandon, except that there is less clay, and that none of the pebbles are limestone.

Wolfshollow near Salisbury, Connecticut. (C. A. Lee, _American Journal of Science and Arts_, 1824, vol. VIII., page 254.)--In the eastern portion of the township, at an altitude of about 800 meters, is a chasm about 100 meters long, 18 meters deep and 12 meters wide. It is in mica-slate, and is sheltered by large trees. At the bottom at one end is a spring of cold water and a cave of considerable extent, in which ice and snow is found the greater part of the year.

Natural Ice House, near Meriden, Connecticut. (Benjamin Silliman, _American Journal of Science and Arts_, 1822, vol. IV., page 174.)--It lies between New Haven and Hartford, about 32 kilometers from the sea, at an altitude of about 60 meters. The ice is found in a narrow defile of perpendicular trap rock, at the bottom filled with broken stones. The defile is so placed that in summer the sun only shines into it for about an hour each day; it is also well protected by surrounding trees, the leaves from which form beds at the bottom among the rocks and help to protect the ice.

Natural Ice House of Northford, Connecticut. (Benjamin Silliman, _American Journal of Science and Arts_, 1822, vol. IV., page 177.)--About 11 kilometers from New Haven on the Middletown road between Branford and Northford, is a gorge where ice remains throughout the year. In this case the ice is mixed with a considerable quantity of leaves and dirt; it has sometimes been brought to New Haven.

Ice in an Old Iron Mine, near Port Henry, Lake Champlain. (_Geology of Vermont_, 1861, vol. I., page 199.)--Ice was found during the summer at a depth of from 15 meters to 30 meters, and a current of cold air was issuing from the opening. There seems to be more than one opening to the mine.

Ice among the Catskill Mountains, New York.--Mr. George Brinton Phillips informs me that he has seen subterranean ice in August among boulders in a gorge in the Catskills near the Stony Cloves road, starting out from Haines' Falls. The people in the neighborhood speak of the place as an ice cave.

Gorge in the Shawangunk Mountains, near Ellenville, Ulster County, New York. Described in Part I., page 91. (Heilprin, _Around the World_, 1894, page 194.)--Professor Heilprin found in July a mass of ice measuring about thirty meters in length and 1 meter in depth. The thermometer near the ice read about 1° C. above freezing point, the day being hot. Icicles hung from the ledges on the side of the gorge.

Freezing Well near Owego, New York. Described in Part I., page 74. (D. O. Macomber, _American Journal of Arts and Sciences_, 1839, vol. XXXVI., page 184. _Well's Annual of Scientific Discovery_, 1856, page 190.)--The thermometer is said to have stood at--1.2° at the bottom of the biggest well when it registered--20° outside. When a candle was let down, the flame became agitated and was thrown in one direction at the depth of 9 meters; at the bottom the flame was still, but soon died out. Large masses of ice were found in the biggest well as late as July, and the men who made the well were forced to put on thick clothing in June, and even so could not work for more than two hours at a time.

Cave in the Panama Rocks, Chautauqua, New York. The Rev. Horace C. Hovey informs me that he has been in a small cave in this locality, and that he found ice in it.

Cave in Sussex County, New Jersey.--A clipping from a newspaper, with neither name nor date, says that new ice is found daily on the land of Peter Feather, in the mouth of an unexplored cavern. A small stream of water runs out of the cavern and forms a pool at the opening, and here it is that the ice forms. Enough has been taken in one day to freeze two cans of ice cream. A cold draught of air issues continuously from the cavern.

Hole Containing Ice on Blue Mountain, New Jersey. Reported; no information.

Gorge Containing Ice on Bald Eagle Mountain, Clinton County, Pennsylvania.--Mr. Henry Chapman Mercer, of Doylestown, learned of the existence of this gorge during the summer of 1897. It is near the village of McElhatten, in the neighborhood of Lock Haven, and is some 3 kilometers distant from the Susquehanna River. Ice is said to remain over during the entire summer.

Freezing Cave and Windholes near Farrandsville, Clinton County, Pennsylvania.--Described in Part I., page 93.

Underground Ice Formations, Sullivan County, Pennsylvania, on the southwestern borders of Lycoming County.--Mr. W. Coleman Hall of Philadelphia, about twenty years ago, found ice in two or three places, on Bear Creek, north of Muncy Creek, about 25 kilometers north of the Susquehanna River, and southwest of Eagles Mere. The ice was under rocks, in what may be described as limestone sinks. Since the destruction of the forest, the ice has become less abundant, if indeed any still forms.

Glacières in Abandoned Coal Mines near Summit, Carbon County, Pennsylvania.--Described in Part I., page 95.

Ice Cave Railroad Station, Luzerne County, Pennsylvania. On the Bowman Creek branch of the Lehigh Valley R. R.--Mr. F. Holschuh, agent at Luzerne, informs me that about 2 kilometers from Ice Cave Station is a little waterfall on the side of a mountain which was formerly covered with dense forest. A short distance below the fall, a large hollow place has been worn out of the rocks by the action of the water. The overhanging rocks give this almost the appearance of a cave. While the forest was still thick and when the winter was cold, ice would form under these rocks and would not disappear until summer was well advanced. The station was called Ice Cave on account of this place.

Hole Containing Ice at Millerstown, Pennsylvania.--Reported; no information.

Freezing Talus at Spruce Creek, Huntingdon County, Pennsylvania. Described in Part I., page 90. The _Philadelphia Ledger_ of July 6th, 1896, states that around the boulders where the ice lies, there are found varieties of plants strongly arctic in character.

Ice Mountain, Hampshire County, Virginia. (C. B. Hayden, _American Journal of Science and Arts_, 1843, vol. XLV., page 78.)--It lies on the North River, near the road leading from Winchester to Romney, at an altitude of from about 220 meters to 240 meters. One side of the hill is entirely composed of loose stones, among which an abundance of ice is found at all times, although the sun shines on the upper surface of the stones from ten in the morning until sunset. The ice is regularly used in summer by the people near by. Constant and strong air currents issue from the crevices in the rocks. Similar, but smaller accumulations, are said to occur in the same county. Mrs. George B. Balch visited the Ice Mountain in August, 1878. She saw no ice, but the air under the stones was very cold.

Blowing Cave, Bath County, Virginia.--Mrs. Horace Jayne informs me that there is a blowing cave near the Cowpasture River, about half way on the old stage road between Millboro and Warm Springs. A draught flows out from it, strong enough to blow the grass about, three or four meters away. The draught is cold, perhaps abnormally so. The cave has not yet been explored.

SOUTH AMERICA.

Ice Sheets on Mount Chimborazo. (A. von Humboldt, _Travels to the Equinoctial Regions_, London, 1814, vol. I., page 156.)--"On Chimborazo, enormous heaps of ice are found covered with sand, and in the same manner as at the Peak [of Teneriffe] far below the inferior limit of the perpetual snows."

Tierra del Fuego. (A. Winchel, _Walks and Talks_, 1898, page 122.)--"On Tierra del Fuego ice and lava are found interstratified for a great depth, each winter's snow being covered by a new lava sheet."

TENERIFFE.

La Cueva de la Nieve or del Hielo. (Humboldt, _Travels to the Equinoctial Regions_, 1814, vol. I., pages 154, 156. C. Piazzi Smyth, _Teneriffe, an Astronomer's Experiment_, 1858, page 348.)--La Cueva de la Nieve lies at an altitude of 3267 meters in the Malpays on the Peak of Teneriffe, just below the snow line. It is in obsidian. The entrance is 3.6 meters high and 2.7 meters broad. The grotto is 36 meters long, 6 meters wide, and 4 meters high. The descent into the cave is so steep that it is necessary to be lowered by ropes. Professor Smyth found in July an ice floor about 60 centimeters thick which was covered with water. A good deal of snow was lying near the mouth of the cave. The walls were covered with ice and icicles and a few small ice cones rose on the ice floor.

ICELAND.

The Surtshellir or Cave of Surtur. (Olafsen and Povelsen, _Voyage en Islande_, Paris, 1802. Henderson, _Iceland_, 1819, 2d ed., page 420. Guimard, _Voyage en Islande_, page 481.)--The Surtshellir lies in the volcanic waste of Westisland, and is in lava which has flowed from the Bald Jokul. The approach is through an open chasm. The length of the cave is 1534 meters, with an average width of from 15 meters to 17 meters, and a nearly uniform height of from 9 meters to 11 meters. In four places the roof is broken and allows daylight to enter. A great deal of ice is sometimes found in the cave, in the shape of an ice floor, transparent icy pillars, hanging icy pendants, and columns and arches of ice along the walls. Some of the pillars have been found 2.50 meters high.

Kutlagaya. (A. Winchel, _Walks and Talks_, 1898, page 122.)--"In 1860 the crater of the mountain Kutlagaya, in Iceland, hurled out simultaneously into the air lumps of lava and ice, all intermingled together."

SCANDINAVIA.

Ice in the Mines of Nordmark. (Jars, _Voyages Métallurgiques_, 1774, page 105.)--13 kilometers north of Philipstadt, Wermeland, Sweden, a number of holes were dug, some to a depth of 120 meters. Ice of some thickness formed in some of these towards the end of winter, and lasted until about September, despite the fires of the workmen.

Persberg Iron Mines, Sweden. (J. Prestwich, _Collected papers_, etc., on page 206, quotes Dr. Clark's _Travels in Scandinavia._)--Ice is said to have been found on the sides and bottom of the mine to a depth of about 135 meters.

Ice Caves Reported in Norway.--I was told in Norway that some of the caves in the mountains near the Swartisen ice field contained ice, but I do not know whether this is true. I suspect that there are glacier ice caves which have given rise to this report.

ENGLAND.

Helvellyn, Cumberland. (Wordsworth, _Fidelity_.)--The following verses were pointed out to me by Mr. Bunford Samuel. As far as I know they are the only poetry about glacières:--

"It was a cove, a huge recess That keeps, till June, December's snow; A lofty precipice in front, A silent tarn below! Far in the bosom of Helvellyn, Remote from public road or dwelling Pathway or cultivated land From trace of human foot or hand."

Ice in an Old Copper Mine, Cumberland. (J. Clifford Ward, _Nature_, vol. XI., page 310.)--Ice reported as a rare occurrence.

Ludchurch Chasm, Staffordshire. (R. K. Dent and Joseph Hill's _Historic Staffordshire_, quote Dr. Plot, 1686.)--Mr. Bunford Samuel called my attention to this book, in which Dr. Plot is quoted as saying that as late as the 17th of July, snow has been found in Ludchurch Chasm. Messrs. Dent and Hill do not mention anything of the kind as occurring now.

Blowing Cave in Denbighshire, Wales.--A newspaper cutting says that there are such strong eruptions of winds from a cave in this neighborhood as to toss back to a great height in the air any article of apparel thrown in.

Tin Croft Mine, Cornwall. (J. Prestwich, _Collected papers_, etc., page 206, quotes Mr. Moyle.)--Ice has been found in abundance in this mine at a depth of nearly 100 meters.

Jacques, a l'enseigne du Bichot, 1586, avec privilege du Roy_, pages 436-453. Gollut, _Les Mémoires historiques de la Repub. Sequanoise, et des princes de la Franche Comté de Bourgogne, par M.

The earliest notice of a glacière which I have been able to find is in the shape of a letter giving an account of a visit to the Glacière de Chaux-les-Passavant in 1584, by Benigne Poissenot, a French lawyer. The account, which I have translated as literally as possible, is in a special chapter, as follows:--

"Sir:--Since our separation, I have had this pleasure (_heut_) to hear news of you only once, having found your brother in Paris; who, having assured me of your good health (_disposition_), informed me of how since we had seen each other you had travelled to Italy, even as far as Greece, of which you had seen a large portion: and that sound and safe, after so long a journey, you had reappeared and landed at Havre de Grace where you wished to go, that is to say at home. All the pleasure which a friend can receive, knowing the affairs of another self, joined to such a happy result, seized my heart, at the recital of such agreeable news: and I did not fail shortly after, to write you amply all which had happened to me since I left you until my return to France: congratulating you at having escaped from marine abysses and perilous passages on land, on which travellers are often constrained to risk their life. From this time, I have always stayed in Paris or in the neighborhood, according to the good pleasure of dame fortune, who ruled me in her wise and fed me with her dishes the most common and ordinary until the first day of January of the year 1584, when I received my first gift in the shape of a strong and violent disease, which tormented me more than a month: from which, having become cured with the help of God, and having with time recovered my health and my strength at the arrival of spring, I was seized with the desire to smell the air of the country. And in fact having thrown away my pen and travelled about (_battu l'estrade_) through high and low Burgundy, I stopped at Bezenson, Imperial City, to spend the summer. This city is still to day just the same as Julius Cæsar describes it, in the notable mention he makes of it, in the first book of his commentaries of the war in Gaul, there remaining there all the vestiges of the most remarkable things, which he tells of in his description. There are also very fine fountains, from all of which water streams from the representation of some god of antiquity, as a Neptune, a Bacchus, a Pan, a Nereide or others: except before the state house, where the statue of Charles the Fifth, representing him in a most natural manner, is placed on an eagle, which from its beak, pours out such a great quantity of water that this is the most beautiful, among all the other fountains. And as I do not doubt that while traversing Italy, you both saw and examined with curiosity the most handsome singularities, which presented themselves to your eyes and that on your return, passing through Avignon and Dauphiné, as your brother informed me, you had the advantage over me of seeing the wonders of the country, of which you had heard me speak sometimes, regretting that the war, during the time I was in that quarter, had prevented my going to the spot, to see the burning fountain as in Dodone, and the fountain called Jupiter, which torches of fire light up and which grows less till midday and then grows till midnight, and then diminishes and fails at midday: and another in Epirus which we call to day Albania, the tower without venom and the inaccessible mountain: then as I said, since you have contemplated these things and several others not less admirable, I wish to entertain you about a marvel which I saw, during my sojourn in Bezenson, to know from you, whether in all your journey, you saw a similar thing. Know then that the day of the festival of St. John Baptist, a young man, provided with an honest knowledge, with whom I had made some little acquaintance, presented me with an icicle, to cool my wine at dinner, and which I admired greatly, on account of the time of the year in which we then were, begging him who gave it to me to tell me where he had discovered this rare present for that time. He answered me that every year, the day of the solemnity of the festival of St. John Baptist, the inhabitants of a village, which he named, were bound to come to offer the great church of St. John of Bezenson, a goodly quantity of ice, which they got in a wood, and brought to town at night on horses, for fear that by day it should melt, and that one of his cronies had given to him what he had given to me.

"Suddenly there flamed up in me a desire to see this place, where in the height of the summer, ice was to be found. When he who had presented me with the icicle saw this, he promised to accompany me, not having as yet, any more than myself, seen this marvel. I did not hatch very long this decision, all the more as all those, to whom I mentioned it, encouraged me to carry it out as soon as I could, assuring me that I should see a strange thing, and that even the Duke of Alva on his return from Flanders, passing through Franche Comté, had wished to see this novelty. Therefore calling on the promise of the one who was the cause of undertaking this journey, we went together to Versey, a fine town, distant five leagues from Bezenson, turning a little off our direct route, to go to see a literary man, at this said Versey, who having called on me at Bezenson, had extracted from me the promise of going to see him. There happened to me in this spot, what the poet du Bellay says happened to him, on his return from Italy, passing through the Grisons, to go into France: who, after having chanted the troubles there are in the passage, says that the Swiss made him drink so much, that he does not remember anything he saw in that country. Likewise, I can assure you that my host, following the custom of those of the country (who do not think they are treating a man properly if they do not make him drink a lot, taking that from the Germans, their neighbors) made us carouse so well, that when we went to bed, we were very gay boys. For although we had both made an agreement on the road, yet our host knew so well how to win us over, saying that those who would not drink, gave reason to think badly of them, and that they had committed, or wished to commit some great crime, which they feared to give away in drinking, that in the end we let ourselves go, passing the time in Pantagruelic fashion. The next morning having taken some "hair from the beast" and a guide which our host gave to us to conduct us to the _Froidiere_--we continued our wanderings, and arrived at a little village called Chaud, joining a large wood, where our guide told us, that although he had been more than six times to the _Froidiere_, yet the road was so tortuous and so cut up by small paths, that if we did not take a man from this village, to be more sure, we might spend more than half a day in the wood, before finding what we were seeking. Getting off our horses now, we added to our company a native of the place, who having led us by crooked roads, about a quarter of a league, through the forest, made us enter into a close thicket and by a little path led us to a pleasant meadow; where, looking down, we saw a hole, of difficult descent, at the bottom of which was the opening of a grotto, pretty big, and so awful and terrifying to see, that one would have said, it was the mouth of Hell. And in truth, I remembered then, the hole of St. Patrick, which is said to be in Hibernia. We were not brave enough knights, to try the adventure, my companion and I, if our guides had not taken the lead. After whom we descended as magnanimously as the Trojan Duke followed the Sybil to the Plutonic realms, the sword half drawn from the scabbard, and well determined to make test of the Platonic doctrine, which teaches that demons can be dissected, in case any shade or spook should have come to meet us. About the middle of the way, we began to feel in descending a very agreeable freshness; for it was the second day of July and the sun shone very warmly, which made us sweat drop by drop. But we had good opportunity to refresh ourselves and put ourselves to cool, having reached the grotto which we found of the length and breadth of a large hall, all paved with ice in the bottom, and where a crystalline water, colder than that of the mountains of Arcadia Nonacris, streamed from many small brooklets, which formed very clear fountains, with the water of which I washed myself and drank so eagerly, that I had wished the thirst of Tantalus, or else that I had been bitten by a Dipsas, in order to be always thirsty, amid such a pleasant beverage. A great lord, who in some pleasure resort, should have such a refrigerator in summer, could boast according to my judgment, to be better provided with drink, than the kings of Persia were with their river Coaspis, which engulphs itself into the Tigris, the water whereof was so sweet, that the use of it was allowed only to the great King, for the retinue and cronies of his household. Do not think, that among these delights, I was at all free from fear, for never did I raise my eyes above that from terror my whole body shivered and the hair stood up on my head, seeing the whole roof of the grotto, covered with big massive icicles, the least of which, falling on me, had been sufficient to scramble up my brains and knock me to pieces; so much so that I was like to that criminal, whom they say is punished in Hell, by the continual fear of a big stone, which seems as though it must suddenly fall on his ears. There are besides the large hall of the grotto, some rather roomy corners, where the gentlemen of the neighborhood, put their venison to cool in summer, and we saw the hooks, where they hang the wild fowl. It is true, that when we were there, we saw neither game nor wild fowl, and I think, that if we had found any of it, we were men to carry off some of it. We walked around for about a quarter of an hour, in this _Froidiere_ and we should have staid there longer if the cold had not driven us out; which struck in to our backs, even to make our teeth crack; we reascended the slope, not forgetting, all of us as many as we were, to provide and load ourselves with ice, which served us at lunch in the little village mentioned above to drink most delightfully, assuring you that it is impossible to drink more freshly than we drank then. I thought of those old voluptuaries, who cooled their wine with snow, and it seemed to me, as though they might have had it much cheaper if in their time there had been many such _Froidieres_, to refresh it with ice, instead of with snow, as some of the gentlemen of the neighborhood of the _Froidiere_ and some of the most notable persons of the neighborhood of Bezenson do; who by night, have a good supply brought on horses, which they keep in their caves, and use at their meals and banquets. Turning back towards the Imperial city of Bezenson, I carried for about two great leagues, a rather large icicle in my hands, which little by little melted and was a pleasant and agreeable cooler, on account of the great heat of the weather. After having thought over in my mind, the cause of this _antiperistase_, I could find none other but this: to wit, that as heat domineers in summer, the cold retires to places low and subterranean, such as is this one, to which the rays of the sun cannot approach, and that in such an aquatic and humid place, it operates the results, which we have shown above. Which seemed to me so much more likely, that on asking the peasants of the neighboring village, if in winter there was ice in this _Froidiere_, they answered me that there was none, and that on the contrary, it was very warm there. Whatever may be the cause, whether this or another, I can assure you, that I admired this singularity as much as any I have seen, since a large church, cut into a rock which I had seen a few years previously, in a little town of Gascony called St. Milion, distant seven leagues from Bordeaux; on the steeple of which is the cemetery, where they bury the dead; a thing to be marvelled at by him who has not seen it.

"I have made trial, to enrich this missive, with all the artifice which has come into my head, using the leisure, which the present time brings me: as the temple of Janus is open, the air beyond breathing nothing but war: which forces me, against my wish, to sojourn in this place longer than I had intended. If these troubles settle down, and if after the rain, God sends us fine weather as requires the calamitous state in which is now the flat country, I shall return to my Parnassus; from which if I go out hereafter, believe that it will be very much in spite of myself, or that my will will have very much changed. You will be able to let me hear from you there, and take your revenge for the prolixity of this letter, by sending me one still longer, which you will write to me with more pleasure, as I shall take much in reading it. However as it is becoming time to sound taps, I will pray the sovereign creator for my affectionate recommendations to your graces.

"Sir, and best friend, may you keep in health and have a long and happy life. From Sens this 20th of June 1585.

"Your obedient friend, BENIGNE POISSENOT.

"End of the description of the marvel, called the _Froidiere_."

The next notice about the Glacière de Chaux-les-Passavant is by Gollut in 1592, as follows:--

[Sidenote: "Ices in summer."]

"I do not wish however to omit (since I am in these waters) to bring to mind the commodity, which nature has given to some dainty men, since at the bottom of a mountain of Leugné ice is found in summer, for the pleasure of those who wish to drink cool. Nevertheless at this time, this is disappearing, for no other reason (as I think) except, that they have despoiled the top of the mountain, of a thick and high mass of woods, which did not permit that the rays of the sun came to warm the earth, and dry up the distillations, which slipped down to the lowest and coldest part of the mountain where (_by antiperistase_) the cold got thicker, and contracted itself against the heats surrounding and in the neighborhood during the whole summer, all the external circumference of the mountain."

The ice at Chaux-les-Passavant is said to have been entirely cleared out, by the Duc de Lévi, in 1727, for the use of the Army of the Saone. In 1743, when de Cossigny visited the cave, the ice was formed again. There are no reports about the intervening time between 1727 and 1743. The ice probably all re-formed the winter after it was taken away.

Captain Trouillet in 1885 writes of Chaux-les-Passavant: "The following winter had shown itself unfavorable to the production of ice, the periods of humidity preceding too long ahead the periods of frost. Finally last summer, coming after a wet spring, was exceptionally warm. Such were the circumstances which brought about in the glacière the ruin which could be seen at the end of last October. * * * On the 11th of November, the first effects of frost are felt and the temperature falls in the glacière to -2°: outside the thermometer drops to -3°. On the morning of the 12th, same result, and ice makes its appearance in the grotto, as the report of the observer shows: but the quantity produced is so small that the internal thermometer soon goes above 0°. It is only on the 9th of December that the frost wins definitely; on the 11th, 12th and 13th the chill is intense and reaches -19° outside, stopping at -15° in the glacière. The water coming from the rains between the 5th and the 9th drip at this time through the roof and the big side crevasse: circumstances grow favorable and the ice accumulates. From the 17th, the entrance slope becomes almost impracticable; the icicles grow on the roof, as big as the body of a man. * * * From this time to the end of December, the ice sheet does not increase, for water only arrives by the rare drip of the roof, and only the stalactites increase slowly. Outside, however, the cold continues vigorously, the thermometer on the 31st of December dropping to -15° and to -13° in the glacière. If the production of the ice stops, it is not the cold which is wanting, but the other element, the one which as our former study showed, is the most rarely exact at the meeting. The winter is only favorable on condition that it offers alternating periods of freezing and thawing; so the observer writes in his report: 'it is the water which is wanting, otherwise the glacière would be magnificent.'"

Trouillet speaks of the difficulty of winter observations in the following words: "Mons. Briot, the present lessor of the glacière, has the unpaid mission of going every week to the bottom of the grotto to get and put in place the interior thermometer. It is a really hard piece of work at this time of the year: each journey takes about one hour. Besides the chance that a visitor has of receiving on his head one of those magnificent stalactites 1 meter or 2 meters long which fall continually from the roof, it is perfectly disagreeable to him to arrive at the base of the slope otherwise than on the sole of his boots, and to face thus the frequent and painful meeting with rocks whose angular edges dot the surface of the descent, smooth as a mirror set at an angle of 30°."

Trouillet and Girardot obtained a series of observations with maxima and minima thermometers at Chaux-les-Passavant during the winter of 1885-1886. At the end of November the temperature inside was +2°. On the 2d of December it rose to +2.5°. On the 10th of December, it sank to -1°, and after this date, it remained below freezing point all winter. The observations were not continuous, but they showed that every time the temperature outside dropped considerably, the temperature inside immediately did likewise. For instance, on the 12th of January, the outside air dropped to -18°, and the inside air responded by falling to -15°. On the other hand, when the temperature outside rose above freezing point, the temperature inside remained stationary or fluctuated only gently. For instance, from the 24th of March to the 8th of April, the outside air went up and down perpetually, the extremes being -2° and +16°; while in the same time the inside air rose continuously from -2° to -0.5°.

L'Abime du Creux-Percé or Glacière de Pasques. (Martel, _Les Abimes_, 1894, page 394; _Annuaire du Club Alpin Français_, vol. XIX., page 38.)--On the plateau of Langres, Côte d'Or. It lies 15 kilometers from Dijon, and is really a limestone rock gorge, of 55 meters in depth, which at the top is 40 meters long and 20 meters wide, and at the bottom is 15 meters long and 12 meters wide. In March 1892, Mons. Martel found the north side covered with large icicles 15 meters long. The ice seems to remain throughout the year. The bottom of the Abime has been reached only by means of two long rope ladders.

Creux de Chevroche or Roche Chèvre, Côte d'Or. (Clément Drioton, _Mémoires de la Société de Spéléologie_, 1897, vol. I., page 209.)--"In the woods of Mavilly, near Bligny-sur-Ouches, is a little cave, called Creux de Chevroche or Roche-Chèvre, where one can find ice until the month of July."

Freezing Well of Marolles, at La Ferté-Milon, Aisne. (Martel, _Les Abimes_, page 563, note 2.)--This well is 8.15 meters deep; the altitude is 70 meters. During the winter of 1892-93 the water in it froze for a thickness of 15 centimeters. The minimum outside temperature that year was -17°.

Windholes near Pontgibaud, Puy de Dome. (G. Poulett-Scrope, _The Geology and Extinct Volcanoes of Central France_, 1858, page 60.)--These windholes are in basalt. There are many cracks, whence cold air currents issue, and where ice has been found, sometimes in summer. There are cold storage huts over some of the cracks.

Le Creux-de-Souci, Puy de Dome. (Martel, _Les Abimes_, 1894, Page 387.)--This is situated 5 kilometers southeast of Besse-en-Chandesse. It is a large lava cavern with the entrance directly in the middle of the roof. The bottom is partly filled by a lake. The depth from the surface of the ground to the lake is 33 meters; from the smallest part of the opening to the lake the depth is 21.50 meters. Down this last portion one can descend only by means of a rope ladder. The temperature is extremely low; in general near freezing point. In June, July, August and November 1892, Monsieur Berthoule, _maire_ of Besse, did not find any snow. On the 10th of August, 1893, on the contrary, he found at the bottom a heap of snow, which he thinks was formed in the cave itself, by the freezing during their descent of the drops of water which are constantly dripping from the roof. He reports landing on _une montagne de neige, de neige blanche_. On several visits, Mons. Berthoule noticed carbonic acid gas in dangerous quantities. There was none at the time he observed the snow heap, but ten days later he found it impossible to descend into the cave as the carbonic acid gas came up in puffs to the entrance. In the lake, Mons. Berthoule discovered a variety of Rotifer, _Notholca longispina_, and also several algæ and diatoms. The _Asterionella formosa_ is the most remarkable from its abundance: it exists in some of the lakes of the Alps, but not in those of the Pyrenees.

Aven de Lou Cervi, Vaucluse. (Martel, _Les Abimes_, page 563.)--This is a cold cave. It belongs to the class which Mons. Martel calls _avens à rétrécissement_, or _abimes à double orifice_. In September, 1892, Mons. Martel noted a temperature of 6.5° at 53 meters; of 6.8° at 64 meters. Mean temperature of locality, 8.75°.

Igue de Biau, Lot. (Martel, _Les Abimes_, page 304.)--Cold cave. Temperature on 13th July, 1891: 5°.

Fosse Mobile, Charente. (Martel, _Les Abimes_, page 380.)--Cold cave. Temperature on 11th April, 1893: 7°.

Aven de Deidou, Causse Méjean. (Martel, _Les Abimes_, page 223.)--Cold cave. Temperatures on 14th October, 1892: outside air, 4°; at bottom, 6.5°.

Aven des Oules, Causse Méjean. (Martel, _Les Abimes_, page 227.)--Cold cave. Temperatures on 21st October, 1892: outside air, 2.5°; at bottom, 4°.

Windhole Cold Caves near Roquefort, Aveyron.--They lie 13 kilometers from Millau, at an altitude of about 600 meters, and are utilized in the manufacture of Roquefort cheese.

Aven de Carlet, near la Roche Giron, Basses Alpes. (Martel, _Les Abimes_, page 53.)--Lumps of ice are reported to have been taken from it.

La Poujade, Cévennes. (Martel, _Les Abimes_, pages 212-215.)--An intermittent spring in limestone rock. At the bottom of the first gallery, on the 18th of September, 1892, the temperature of the air was 12.3°, and that of a pool of water supplied by drip 11.5°. Mons. Martel thought that the drip brought to the pool the mean annual temperature of the ground through which it had come. A little further within and 5 meters lower, the temperature of the air was 7.3° and that of another pool of water 6.8°. This pool was not supplied by drip and must have been left over by the last flow of the spring. Mons. Martel thought that the lower temperatures at this spot were due to the cold air of winter dropping to the bottom of the cave and on account of its density not being able to get out.

Snow Preserved in Chasms in the Italian Mountains. (_The Penny Magazine_, London, August, 1834, page 335.)--Mr. Bunford Samuel called my attention to an article in which the Southern Italians are said to dig wells or cellars on the mountain sides, and to throw snow into them in winter. The snow is well pressed together and straw, dried leaves, etc., is thrown on top. By having a northern exposure for these pits, and seeing that they are in thick forest, or in rifts where the sun does not penetrate, these depots may be safely placed as low down the mountain as the snow falls and lies. Naples is largely supplied [1834] with snow in summer from such snow wells situated on Monte Angelo, the loftiest point of the promontory separating the Bay of Naples from the Bay of Salerno.

Cold Caves of San Marino, Apennines. (De Saussure, _Voyages dans les Alpes_, 1796, III., page 211.)--These are probably windholes.

La Bocche dei Venti di Cesi. (De Saussure, _Voyages dans les Alpes_, 1796, III., page 211.)--These windholes were in the cellar of the house of Don Giuseppe Cesi, in the town of Cesi. The cellar acted as a natural refrigerator. The air stream was so strong, that it nearly blew out the torches. In winter the wind rushed into the holes. De Saussure was shown the following Latin verses by the owner:--

"Abditus hic ludit vario discrimine ventus Et faciles miros exhibet aura jocos. Nam si bruma riget, quaecumque objeceris haurit. Evomit aestivo cum calet igne dies,"

Windholes or "Ventarole" on Monte Testaceo, near Rome. (De Saussure, _Voyages dans les Alpes_, 1796, III., page 209.)--There are a number here among heaps of broken pottery. The temperatures seem abnormally low.

Krypta Sorana. (Kircher, _Mundus Subterraneus_, 1664, page 118 and page 239.)--This has been spoken of as a glacière cave, but as there is much doubt in the matter, I quote the passages, on which the reports are based, in the original Latin: "Cryptae sunt naturales, quarum innumerae sunt species, juxta vires naturales iis inditas. Sunt nonnullae medicinali virtute praeditae, quaedam metallicis vaporibus, exhalationibus, aquis scatent, sunt et glaciales, plenae nivibus et crystallo, uti in Monte Sorano me vidisse memini." And further: "Vidi ego in Monte Sorano cryptam veluti glacie incrustatam, ingentibus in fornice hinc inde stiriis dependentibus, e quibus vicini montis accolae pocula aestivo tempore conficiunt, aquae vinoque, quae iis infunduntur, refrigerandis aptissima, extremo rigore in summas bibentium delicias commutato."

Subterranean Ice Sheet, Mount Etna, Sicily. (Lyell, _Principles of Geology, 11th Edition_, chapter XXVI.)--This ice sheet is near the Casa Inglese. Sir Charles Lyell ascertained the fact of its existence in 1828, and in 1858 he found the same mass of ice, of unknown extent and thickness, still unmelted. In the beginning of the winter of 1828, Lyell found the crevices in the interior of the summit of the highest cone of Etna encrusted with thick ice, and in some cases hot vapors actually streaming out between masses of ice and the rugged and steep walls of the crater. Lyell accounts for this ice sheet by the explanation that there must have been a great snow bank in existence at the time of an eruption of the volcano. This deep mass of snow must have been covered at the beginning of the eruption by volcanic sand showered on it, followed by a stream of lava. The sand is a bad conductor of heat and together with the solidified lava, preserved the snow from liquefaction.

Glacière on the Moncodine. (Fugger, _Eishöhlen_, page 13.)--The Moncodine is described as a Dolomite near the Lago di Como. The cave lies up the Val Sasina, two hours from Cortenuova, at an altitude of 1675 meters. The entrance faces north, and is 2.5 meters high and 1.5 meters wide. The average diameter of the cave is 16 meters. The floor is solid ice, which has been sometimes cut for use in the hotels on the Lago di Como and even been sent to Milan.

La Ghiacciaia del Mondole. (Fugger, _Eishöhlen_, page 8.)--The Mondole is a mountain 2375 meters high, near Mondovi, south of Turin. The cave lies on the eastern slope, at an altitude of about 2000 meters. It is hard to get at. The entrance is to the east, and is 2 meters wide and 1.5 meters high. A passageway some 25 meters long leads to a large chamber where there is plenty of ice. In hot summers ice is brought from the cave to Mondovi. _Ghiacciaia_ means freezing cavern in Italian.

La Ghiacciaia del Val Séguret. (Fugger, _Eishöhlen_, page 8.)--It lies near Susa at the base of chalk cliffs, at an altitude of about 1500 meters. The cave is said to be about 40 meters deep, 50 meters wide and 50 meters high. Bonetti in May, 1874, found many icicles and ice cones.

La Borna de la Glace. (Chanoine Carrel, _Bibliothèque Universelle de Genève_, 1841, vol. XXXIV., page 196.)--It lies in the Duchy of Aosta, commune of La Salle, on the northern slope of the hills near Chabauday, in a spot called Plan Agex. The altitude is 1602 meters. The entrance opens to the east and is 60 centimeters wide and 80 centimeters high. One can descend for 4 meters. There are two branches in the rear of the entrance. Chanoine Carrel found an ice pillar 1 meter high in the western branch. He recorded these temperatures on the 15th of July, 1841: Outside +15°. Entrance +2.9°. East branch +0.9°. West branch +0.5°.

Windholes in the Italian Alps. (Fugger, _Eishöhlen_, pages 94-97.)--A number of these seem to have abnormally low temperatures. Some are in the mountains around Chiavenna, and are sometimes, by building small huts over them, utilized as refrigerators. Some are reported in the neighborhood of the Lago di Como near Dongo, near Menaggio, and in the villa Pliniana near Curino; in the neighborhood of the Lake of Lugano at the base of Monte Caprino, near Melide, near Mendrisio and near Sertellino; and in the Val Maggia near Cevio.

The Glacière de Font d'Urle, or Fondurle, Dauphiné. (Héricart de Thury, _Annales des Mines_, vol. XXXIII., page 157; G. F. Browne, _Ice Caves_, etc., page 212; E. A. Martel, _Mémoires de la Société de Spéléologie_, vol. I., page 37; L. Villard, _Spélunca_, 1896, vol. II., page 39.)--It lies on the Foire de Font d'Urle, 16 kilometers north of Dié, 48 kilometers east of Valence, and 80 kilometers south of Grenoble. The glacière consists of two large pits, lying east and west, and with underground communication. From this tunnel a long low archway leads to a broad slope of chaotic blocks of stone, which is 60 meters long and 42 meters in greatest width. The ice begins half way down this slope, fitfully at first and afterwards in a tolerably continuous sheet. Thury found many icicles hanging from the roof. Browne found four columns of ice, of which the largest was 5.80 meters across the base. On his visit, in the middle of August, the ice was strongly thawing. Both explorers noted the extremely prismatic character of the ice. Browne found a temperature of +0.5°. Martel gives a section and plan of Font d'Urle. Mons. Villard says about this cavern: "A curious thing: I found in this cave, motionless on a piece of rock, entirely surrounded by ice for a distance of several meters, a blind specimen of a coleoptera, _Cytodromus dapsoïdes_."

The Chourun Clot. (E. A. Martel, _Sous Terre_. _Annuaire du Club Alpin Français_, vol. XXIII., 1896, pages 42, 43; _Mémoires de la Société de Spéléologie_, vol. I., page 31.)--In Dauphiné, half way between Agnières and the Pic Costebelle, at an altitude of 1,740 meters. There is first a pit 18 meters long, 4.50 meters wide and 25 meters deep. In the bottom of this is a vertical hole 15 meters deep and from 1 meter to 2 meters in diameter, in which there was much ice on the 31st of July, 1896. Then the pit changes to a sloping gallery which terminates in a little hall, full of ice, at a depth of 70 meters. Martel gives a cut and section of this glacière.

The Glacière du Trou de Glas. (E. A. Martel, _La Géographie_, 1900, vol. I., page 52.)--In the range of the Grande Chartreuse.

The Chourun Martin. (E. A. Martel, _La Géographie_, 1900, vol. I., page 53.)--In the range of the Dévoluy, Hautes-Alpes; altitude 1,580 meters. An extremely deep pit, which on July 31st, 1899, was much blocked up with snow.

The Chourun de la Parza. (E. A. Martel, _La Géographie_, 1900, vol. I., page 54.)--In the range of the Dévoluy, Hautes-Alpes; altitude 1,725 meters. A fine pit, 25 meters in diameter, and 74 meters in depth. Filled with snow or rather névé, in which are deep holes.

The Glacière de l'Haut-d'Aviernoz. Described in Part I., page 2. (C. Dunant, _Le Parmelan et ses Lapiaz_, page 26; Browne, _Ice Caves_, etc., page 157.)--Mons. Dunant calls this glacière l'Haut d'Aviernoz; Mr. Browne calls it the Glacière du Grand Anu. By a plumb line held from the edge of the larger pit, Browne found that the ice floor was about 35 meters from the surface, which would give a level for the ice floor closely identical to the one I found. In July, 1864, he recorded a temperature of +1.1°.

The Glacière de l'Enfer. (G. F. Browne, _Good Words_, November, 1866; T. G. Bonney, _The Alpine Regions_, 1868, pages 95, 96; C. Dunant, _Le Parmelan et ses Lapiaz_, page 25.)--On Mont Parmelan. A pit cave with a steep slope of broken rock leading to a rock portal in the face of a low cliff. This opens into a roughly circular hall about 22 meters in diameter and 3 meters to 4 meters in height. A chink between the rock and the ice permitted Mr. Browne to scramble down three or four meters to where a tunnel entered the ice mass. Throwing a log of wood down this tunnel, a crash was heard and then a splash of water, and then a strange gulping sound. "The tunnel obviously led to a subglacial reservoir and this was probably covered by a thin crust of ice; the log in falling had broken this and then disturbed the water below, which then commenced bubbling up and down through the hole, and making a gulping noise, just as it does sometimes when oscillating up and down in a pipe."

Mons. C. Dunant of the _Club Alpin Français_ describes a visit to the Glacière de l'Enfer. He mentions also a legend of a witch from a neighboring village who would get the ice from these caves and bring it down in the shape of hail on the crops of the peasants who were inhospitable to her.

The Glacière de Chapuis. Described in Part I., page 5. (Browne, _Ice Caves_, etc., page 182, and _Good Words_, November, 1866.)--Mr. Browne calls it the Glacière de Chappet-Sur-Villaz. Mr. Browne and Professor T. G. Bonney found several flies in the Glacière de Chapuis. Three of them were specimens of _Stenophylax_, the largest being probably, but not certainly, _S. hieroglyphicus_ of Stephens. Two smaller caddis flies were either _S. testaceus_ of Pictet or some closely allied species. One other insect was an ichneumon of the genus _Paniscus_, of an unidentified species. It differed from all its congeners in the marking of the throat, resembling in this respect some species of _Ophion_. Mr. Browne thinks that the case flies may have been washed into the cave somehow or other in the larva form, and come to maturity on the ice where they had lodged. But this explanation will not hold in the case of the ichneumon, which is a parasitic genus on larvæ of terrestrial insects.

The Glacière de Le Brezon. (Pictet, _Bibliothèque Universelle de Genève_, 1822, vol. XX., page 270, and Thury, _Bibliothèque Universelle de Genève_, 1861, vol. X., pages 139 and 152.)--It lies southeast of Bonneville near the foot of Mount Lechaud, at an altitude of 1276 meters. The cave is 9.7 meters long, about 8 meters wide and the greatest height is about 4 meters. The entrance is small and is at the base of a cliff, in some places of which cold air currents issue. The ice lies on the floor. Some of it is probably winter snow.

The Glacière de Brisons.--Described in Part I., page 1.

The Grand Cave de Montarquis. Described in Part I., page 70. (Thury, _Bibliothèque Universelle de Genève_, vol. X., pages 135-153.)--Professor Thury describes two visits to this cave. On the 16th of August, 1859, he found no ice stalactites or stalagmites. On the 19th of January, 1861, he did not find a single drop of water in the cave, but many stalactites and stalagmites of beautiful clear ice, one of which resembled porcelain more than any other substance. In August, Thury found an air current streaming into the cave at the rear, but this did not, however, disturb the air of the interior, for in one part it was in perfect equilibrium: along the line of the draughts the ice was more melted than elsewhere in the cave. In January, the current was reversed and poured into the fissure, with the temperature varying between -1.5° and -2.5°. He observed the following temperatures at the Grand Cave:--

TIME. OUTSIDE. INSIDE. 16th August, 1859 +8.6° +2.5° 19th January, 1861 1.25 P. M. +2.6° -4.° " " " 2.12 " +2.1° -4.° " " " 3.50 " -1.1° -4.°

The Petite Cave de Montarquis. Mentioned in Part I., page 71. (Thury, _Bibliothèque Universelle de Genève_, 1861, vol. X., page 150. Also quotes Morin.)--At the end of a crooked fissure 10 meters deep, a passage 6 meters long, leads into a cave 8 meters high and 5 meters in diameter. In August, 1828, Morin found an ice stalagmite of 5 meters in height in the middle of the cave.

Cave Containing Ice on the Southern Shore of Lake Geneva.--Reported; no information.

The Glacière and Neigière d'Arc-Sous-Cicon. (Browne, _Ice Caves_, etc., page 118.)--These lie close together in the Jura about twenty kilometers from Pontarlier. The little glacière is formed by a number of fissures in the rock, disconnected slits in the surface opening into larger chambers where the ice lies. The neigière is a deep pit, with a collection of snow at the bottom, much sheltered by overhanging rocks and trees. A huge fallen rock covers a large part of the sloping bottom of the pit, which forms a small cave in the shape of a round soldier's tent, with walls of rock and floor of ice.

The Glacière de la Genollière. Described in Part I., page 48. (Browne, _Ice Caves_, etc., page 1.)--Mr. Browne observed in 1864 a temperature of +1.1°, and two days later of +0.8°. He also found a number of flies running rapidly over the ice and stones. He was told in England, from the specimen he brought away, that it was the _Stenophylax hieroglyphicus_ of Stephens or something very like that fly.

The Glacière de Saint-Georges. Described in Part I., page 62. (Thury, _Bibliothèque Universelle de Genève_, 1861, vol. X.)--Professor Thury obtained the following temperatures at the Glacière de Saint-Georges:--

Professor Thury's winter excursions caused him to accept as proved that part of the mountaineers' belief, which holds that there is no ice formed in caves in winter. One of the main grounds for his opinion was the series of observations he made in the Glacière de Saint-Georges. He found no ice forming there in winter and the natives said it did not because the cavern was not cold enough. So he placed large dishes filled with water in the cave and found that they froze solid during the night, which he had been assured was impossible. Thury also found violent movements of the air at Saint-Georges in January, 1858. A candle burned steadily for some time, but at 7.16 P. M. it began to flicker and soon inclined downwards through an angle of about 45°; and in the entrance, the flame assumed an almost horizontal position. At 8 P. M., the current of air nearly disappeared. Thury thought that this violent and temporary disturbance of equilibrium was due to the fact that as the heavier air outside tended to pass into the cave, the less cold air within tended to pass out; and the narrow entrance confining the struggle to a small area, the weaker current was able for a while to hold its own.

The Glacière du Pré de Saint-Livres. Described in Part I., page 65. (Browne, _Ice Caves_, page 40.)--Mr. Browne found, in 1864, a temperature of 0°.

The Petite Glacière du Pré de Saint-Livres. (Browne, _Ice Caves_, page 46.)--This is near the last cave at a slightly higher altitude. There is first a small pit, then a little cave, in which there is an ice slope. This passes under a low arch in the rock wall, and leads down into another small cave. Mr. Browne descended this ice stream, which was itself practically a fissure column and spread into the fan shape at the base. The lower cave was 22 meters long and 11 meters wide, and contained an ice floor and several fissure columns.

The Glacière de Naye, above Montreux, Switzerland. (E. A. Martel, _Les Abimes_, page 397; _Spélunca_, 1895, vol. I., pages 107, 108; _Mémoires de la Société de Spéléologie_, vol. III., pages 246-254.)--This is called a _glacier souterrain_. It was discovered in 1893 by Professor Dutoit. There are fifty-four caves known among the Rochers de Naye, and only this one contains ice. It is a long narrow cave with two entrances and widest towards the base, which opens over a precipice. The altitude is high, the upper entrance being at an altitude of 1820 meters, and the lower of 1750 meters. The place is both a passage cave and a windhole. The snow falls into the upper entrance, and slides down, becoming ice in the lower portion. There are other connecting passages and hollows where the cold air cannot get in, and there ice does not form. Mons. Martel thinks that the ice formed during the winter is preserved by the draughts--due to the difference in level of the two openings--causing an evaporation and chill sufficient for the purpose.

The Creux Bourquin. (E. A. Martel, _Les Abimes_, page 397.)--At Mauberget, near Grandson. This is a rock gorge 25 meters deep. At the bottom, on the 9th of July, 1893, was a mass of ice 38 meters long and 8 meters wide.

The Glacière de Monthézy. (Browne, _Ice Caves_, page 97.)--This lies to the west of Neufchâtel, between the Val de Travers and the Val de Brévine, on the path between the villages of Couvet and Le Brévine, at an altitude of 1100 meters. The cave is nearly oval in shape, with a length of 34 meters and a width of 29 meters. The roof is from 1 meter to 3 meters high. There are three pits, about 20 meters deep, on different sides of the cave. The descent is made through the largest pit. On the 6th of July, 1864, Mr. Browne found the floor of the cave covered with ice, and icicles and columns in some places; he also saw a clump of cowslips (_primula elatior_) overhanging the snow at the bottom of the pit through which he descended.

Pertius Freiss. (T. G. Bonney, _Nature_, vol. XI., page 327.)--It lies on the way to the Pic d'Arzinol, near Evolène, in the Val d'Hérens. A slip or subsidence of part of a cliff has opened two joints in the rock, in both of which fissures Professor Bonney found ice on July 23d.

The Schafloch. Described in Part I., page 21. (Körber, _Jahrbuch des Schweizer Alpen Club_, 1885, vol. XX., pages 316, 343.)--Herr Körber gives some of the dimensions as follows: Entrance 14 meters wide and 4.70 meters high. Length of cave 206.8 meters: average width 20 meters and greatest width 23.5 meters. Height from 5 meters to 7 meters. Length of ice slope 29 meters and breadth 12.5 meters; for 16 meters the slope has an inclination of 32°. Körber made the following observations in the Schafloch:--

The Rev. G. F. Browne, in 1864, found a temperature of +0.5°.

The Eisloch of Unterfluh. (Baltzer, _Jahrbuch des Schweizer Alpen Club_, 1892-93, pages 358-362.)--Twenty minutes from Unterfluh near Meiringen. A long narrow rock crack, some 30 meters deep and running some distance underground.

Windholes and Milkhouses of Seelisberg.--Described in Part I., page 45.

Windholes on the Spitzfluh. (Fugger, _Eishöhlen_, page 92.)--These are situated between Oltingen and Zeylingen, Canton Bâle: they generally contain ice till the end of July.

Windholes on the Blummatt. (Fugger, _Eishöhlen_, page 93.)--On the northwestern slope of the Stanzerberg. Ice sometimes lies over in these windholes.

Windholes near Bozen. (Fugger, _Eishöhlen_, page 97.)--On the Mendel ranges in Eppan, southwest of Bozen, among porphyry rocks. There are strong wind-streams. Ice is said to remain till late in the summer.

Grotto on Monte Tofana, Dolomites. (T. G. Bonney, _Nature_, vol. XI., page 328.)--This is probably a rudimentary glacière.

Holes with Ice near Lienz. (Fugger, _Eishöhlen_, page 97.)--One hour and a half distant near Aineth, is a small cave containing ice, and further up the valley towards Huben, are several windholes.

Eishöhle am Birnhorn. (Fugger, _Eishöhlen_, page 131.)--Near Leogang in the Pinzgau. Altitude 2150 meters. There are two entrances, from which a slope 10 meters long, set at an angle of 25°, leads to an ice floor 12 meters long and 3 meters high. Then comes a small ice slope, and a little horizontal floor at the back. Explored by Fugger.

Glacières on the Eiskogel. (Fugger, _Eishöhlen_, page 19.)--The Eiskogel is in the Tennengebirge, a mountain mass lying east of Pass Lueg. At an altitude of about 1900 meters, are two small caves, about 30 meters to 40 meters apart. They are some 25 meters in length and get smaller towards the bottom.

Holes with Ice in the Tennengebirge, between the Schallwand and the Tauernkogel. (Fugger, _Eishöhlen_, page 20.)--In this gorge are some small holes at an altitude of about 2000 meters, which are said to contain ice in summer.

The Seeofen. (A. Posselt-Csorich, _Zeitschrift des Deutschen und Oesterreichischen Alpen Verein_, 1880, page 270.) On the Hean Krail in the Tennengebirge, at an altitude of about 1900 meters. The entrance faces southwest, and is 6 meters high and 4.5 meters wide. The cave is 25 meters long, and 8 meters wide. The floor of the cave is 13 meters below the entrance.

The Posselthöhle. (A. Posselt-Csorich, _Zeitschrift des Deutschen und Osterreichischen Alpen Verein_, 1880, page 273.)--Named after its discoverer. It lies on the Hochkogel in the Tennengebirge, at an altitude of about 1900 meters. The entrance faces southwest, and is about 8 meters high and 8 meters wide. From the entrance the cave first rises, then sinks again below the level of the entrance, where the ice begins. The cave is about 20 meters wide. About 180 meters were explored, to a point where a perpendicular ice wall, 6 meters high, barred the way. About 125 meters from the entrance, there was an ice cone about 7 meters high.

The Gamsloch or Diebshöhle. (Fugger, _Eishöhlen_, page 14.)--It lies on the Breithorn of the Steinernes Meer, near the Riemannhauss, at an altitude of about 2180 meters. The entrance faces south. There is first a small, then a larger chamber. The latter is some 40 meters long, by 5 meters or 6 meters wide. The ice is in the large chamber.

Eishöhle am Seilerer. (Fugger, _Eishöhlen_, page 15.)--On the eastern side of the Seilerer arête on the Ewigen Schneeberg, west of Bischofshofen, at an altitude of about 2400 meters, is a small glacière cave.

Cave in the Hagengebirge, West of Pass Lueg. (Fugger, _Eishöhlen_, page 15.)--It lies about 2 kilometers east of Kalbersberg, at an altitude of about 2000 meters. A snow slope, with an ice floor at the bottom, leads into a long cave, about which little is known.

The Nixloch. Described in Part I., page 57. (Fugger, _Eishöhlen_, page 98.)--Professor Fugger gathered some valuable data in connection with the Nixloch. In August, 1879, he found the air current entering downwards; on September 14th, 1879, there was no current either way. On Christmas day, 1878, on the contrary, the draughts were reversed, pouring out of the hole with a temperature of +7.4°: the outside air then being -7.4°. At this time the known lower opening was in existence.

The Kolowratshöhle. Described in Part I., page 18. (Fugger, _Beobachtungen_, etc., page 7.)--This cavern has been more carefully studied than any other glacière cave. Some of its dimensions are given by Professor Fugger as follows: From the entrance to the ice floor, 26.6 meters; surface covered by ice as measured on a plane, 2940 square meters; approximate cubical measure of entire cave, 92,000 cubic meters. The height of the entrance is 7 meters, with a width at the base of 2.7 meters, and at the top of 6.6 meters.

On the entrance slope occurred the only fatal accident I know of in glacières. In 1866, the Bavarian minister Freiherr von Lerchenfeld tried to descend; a wooden handrail which had been erected over the snow broke under his weight; von Lerchenfeld fell to the bottom of the cave and died a few days after from the injuries he received.

Of the Kolowratshöhle, we have numerous thermometric observations by Professor Fugger, of which I select a few.

The Schellenberger Eisgrotte. (Fugger, _Beobachtungen in den Eishöhlen des Untersberges_, page 80.)--On the southeast slope of the Untersberg near Salzburg, at an altitude of 1580 meters. The path leads past the Kienbergalp over the Mitterkaser and the Sandkaser. In front of the entrance is a sort of rock dam, 30 meters long and 5 meters or 6 meters higher than the entrance. Masses of snow fill the space between the two. The entrance is about 20 meters wide and from 2 meters to 3 meters high. A snow slope of 25 meters in length, set at an angle of 25°, leads to the ice floor. The cave is 54 meters long, from 13 meters to 22 meters broad and from 4 meters to 10 meters high. The cave has been repeatedly examined by Fugger, who has always found most snow and ice in the beginning of the hot weather, after which it gradually dwindles away.

Of the Schellenberger Eisgrotte, we have the following thermometric observations by Professor Fugger:--

The Wasserloch. (Fugger, _Eishöhlen_, page 21.)--On the south slope of the Höllengebirge, near the Spitzalpe. Altitude about 1350 meters. At the bottom of a gorge is a snow heap and a small cave. The snow becomes ice in the cave.

Cave on the Zinkenkogl near Aussee. (Fugger, _Eishöhlen_, page 21.)--Altitude about 1800 meters. A snow slope leads to an ice floor 18 meters long and 4 meters wide.

Cave on the Kasberg. (Fugger, _Eishöhlen_, page 22.)--South of Grünau near Gmunden. Altitude about 1500 meters. Small cave 12 meters long, 4 meters wide.

The Geldloch or Seelücken on the Oetscher. (Schmidl, _Die Höhlen des Ötscher and Die Oesterreichischen Höhlen_; Cranmer and Sieger, _Globus_, 1899, pages 313-318, and 333-335.)--The second known notice of a glacière cave is the account of a visit to the Oetscher Caves in 1591. After lying in manuscript for two and a half centuries, it was published by Dr. A. Schmidl in 1857, in _Die Höhlen des Ötscher_, pages 21-36. According to the account, which is naive, but evidently truthful, Kaiser Rudolf II. ordered Reichard Strein, owner of the Herrschaff Friedeck, to investigate the Ötscher and especially its caves. He did so, with the title of _Kaiserlicher Commissarius_, and accompanied by the _Bannerherr_ Christoph Schallenberger, Hans Gasser, and eleven porters. On September the 16th, 1591, they visited the Seelücken, where they found a lake in the front of the cave, and where the party had great difficulties in climbing round on to the ice.

The Seelücken on the Oetscher is situated at an altitude of 1470 meters. It opens nearly due south. The ice floor is about 20 meters below the entrance and is about 38 meters long and 24 meters wide; at the rear, it rises for some 15 meters as an ice wall at an angle of about 60°, and then forms a second ice floor about 45 meters long by 19 meters wide. The front part of the ice is sometimes, about July, covered with water. The cave continues further back, in two branches, and Professors Cranmer and Sieger consider that it is a large windhole, in which draughts are infrequent, on account of its length and because the openings are near the same level. There are also several up and down curves and in these cold air remains and acts something like a cork in stopping draughts.

On the 13th of September there were no draughts, and the temperatures between 11 A. M. and 12 M. were:--

Outside air +7.1° Inside near entrance +1.5° A little further in +1.1° At the lowest point near ice +0.8°

On the 31st of October, 1897, there was a draught, which followed the curves of the cavern, and which flowed out at the southern end. The temperatures were:--

Outside air +3.7° Inside near entrance +1.3° At the lowest point near ice +0.8° On the second, higher ice floor +1.0° In the main passage behind ice +1.4°

Cave on the Kühfotzen near Warscheneck. (Fugger, _Eishöhlen_, page 25.)--A small cave containing ice.

Eiskeller on the Rax. (Fugger, _Eishöhlen_, page 25; Cranmer, _Eishöhlen_, etc., page 61.)--Altitude about 1660 meters. A doline with a small cave at the bottom, in which melting snow was found on the 19th of September, 1896.

The Tablerloch. (Cranmer, _Eishöhlen_, etc., pages 19-60.)--On the Dürren-Wand in the mountains south of Vienna, 2 hours distant from Miesenbach R. R. station. Altitude about 1000 meters. Entrance 7 meters wide, 3.5 meters high. Slope 30° from entrance. Lowest point 22 meters below entrance. Extreme length of cave 50 meters, width 23 meters, height 15 meters. Professor Cranmer found fresh ice beginning to form on the 12th of November, 1893; on the 1st of December, 1894; and on the 20th of October, 1895. He found it melting away on the 3d of June, 1894; on the 1st of June, 1895; and on the 31st of May, 1896. The rates at which the ice formed or melted, however, were not always the same in different parts of the cave. The greatest amount of ice observed seems to have been in March and April. In the summer months no perceptible movements of air seem to have been noticed. This was also sometimes the case in the winter months, during which, however, movements of air were at other times plainly perceptible.

The Gipsloch. (Cranmer, _Eishöhlen_, etc., page 60.)--A small cave on the Hohen-Wand near Wiener-Neustadt. It is rather a cold cave than a glacière.

Eisloch in the Brandstein on the Hochschwab. (Cranmer, _Eishöhlen_, etc., page 64.)--Altitude about 1600 meters. A moderately large cave. On the 21st of August, 1895, there was an ice floor 10 meters long and 5 meters broad. Temperature in rear of cave, -0.2°.

Caves on the Beilstein. (Krauss, _Höhlenkunde_, 1894, pages 207-219; Cranmer, _Eishöhlen_, etc., page 63.)--These lie about 4 hours on foot from Gams in Steiermark, at an altitude of 1260 meters, in a place where the mountain is much broken up by fissures and snow basins. The large cave has two openings, from which steep snow slopes descend. The cave is 60 meters long, 15 meters to 18 meters broad, and about 7 meters high. Clefts in the rock in two places lead to two lower, small ice chambers. In the neighborhood of the large cave are two small ones. Prof. Cranmer found fresh ice in the Beilsteinhöhle on the 20th of August, 1895. Two days before, fresh snow had fallen on the neighboring mountain peaks.

Eishöhle on the Brandstein. (Cranmer, _Eishöhlen_, etc., page 62.)--A small cleft cave near the Langriedleralm near Gams in Steiermark. On the 20th of August, 1895, it contained some ice.

The Frauenmauerhöhle.--Described in Part I., page 37.

The Bärenloch near Eisenerz. (Fugger, _Eishöhlen_, page 28.)--In the neighborhood of the Frauenmauerhöhle. Altitude 1600 meters. A steep snow slope leads to an ice floor 13 meters long.

Caves in the Stein Alps. (Fugger, _Eishöhlen_, page 29.)--The plateau of Velica Planina lies, at an altitude of 1600 meters, 9 kilometers north of Stein in the Duchy of Krain. There are three caves containing ice on the plateau. The first is a big one and is called V. Kofcih. The second is called Mala Veternica. The third and biggest is called Velika Veternica; its length is about 100 meters and its breadth 30 meters.

Glacière Caves on the Nanos Mountain. (Fugger, _Eishöhlen_, page 34.)--In the southwestern Krain, 5 kilometers from Präwald. There are four caves containing ice reported on the Nanos mountain. Two of them are big. The altitude of one of these is 1300 meters, of the other 1350 meters.

At Divacca -2° C. In the Kacna Jama at 40 meters -1.1° C. " " " " " 100 meters +1.2° C. " " " " " 210 meters +2.1° C.

Sanct Canzian, Karst. (E. A. Martel, _Les Abimes_, page 564, note.)--During the winter of 1889-1890, Herr Marinitsch found stalactites of ice as far as the seventeenth cascade of the Recca; 1000 meters from the third entrance of the river. The temperature of the Recca was then at 0°; during the summer, the temperature of the water rises to 27° (?).

The Grosses Eisloch of Paradana. (Fugger, _Eishöhlen_, page 36.)--On the high plateau of the forest of Tarnowa, east of Görz. A large pit cave, 30 meters to 40 meters deep. Professor Fugger says of it: "The flora in the basin-like depression has the character of high mountain vegetation, with every step it resembles more this flora as it exists in the neighborhood of glaciers, until finally in the deepest point of the basin all vegetation stops."

The Kleines Eisloch of Paradana. (Fugger, _Eishöhlen_, page 37.)--A small pit glacière, 500 meters distant from the Grosses Eisloch of Paradana.

Suchy Brezen. (Fugger, _Eishöhlen_, page 37.)--A small pit glacière, situated about midway between the Grosses and Kleines Eisloch of Paradana.

Glacière Cave near Lazhna-gora or Latzenberg. (Valvasor, _Die Ehre des Herzogthumes Crain_, vol. I., pages 242, 243; Hacquet, _Oryctographia Carniolica_, 1778, III., page 159.)--In the neighborhood of Vishnagora in the Krain. The entrance is under a church. It is a large cave, 40 meters long and 20 meters high, where the ice all melts by the end of the summer. Valvasor gives the following account of this cave in 1689, which seems the first printed notice of a glacière in German:--

"Near to Lazchenberg up by the church of St. Nicholas, where a _Thabor_ stands, one finds a big hole, which sinks into the stony rocks. Through this one descends deep with torches: there opens then underneath as big a cavity as the biggest church could be, and the same is extremely high, in the form of a cupola. One sees there different teeth, formed and hardened from the water turned to stone. Further down one arrives to a deep gully: into which, however, I have not been. On the other side one must again ascend, and then one comes again to a cupola: in which cupola ice stands up like an organ from the earth.

"There also one sees icicles of pure ice of different sizes and heights, of which many are one or two _klafters_ high and as thick as a man; but many only two or three spans high or higher, and as thick as an arm, and some also thinner. This ice is formed from the drops of falling water; and indeed in summer; for in winter there is no ice therein. Over such ice one must then ascend, as there are then said to be separate holes and grottoes. But no one has been any further."

Glacière on the Dini Verh. (Petruzzi in Haidinger's _Berichte_, etc., vol. VII., page 67.)--Near Tomischle in the Krain. Small glacière.

Eiskeller near Rosseck. (Petruzzi in Haidinger's _Berichte_, etc., vol. VII., page 64.)--On the Pograca Mountain in the Krain, northeast of the Hornwald, near the Meierhof Rosseck. Small glacière cave.

Gorge near Rosseck. (Valvasor, _Die Ehre des Herzogthumes Crain_, vol. I., page 243 and page 517 ; Petruzzi in Haidinger's _Berichte_, etc., vol. VII., page 64.)--Behind the ruined castle of Rosseck, on the Pograca Mountain in the Krain, is a gorge, at whose bottom are four little holes containing ice most of the year.

Valvasor wrote of this cave in 1689: "Near Rosseck immediately back of the castle there opens a mighty cavern entirely in stony rock, and yawns in the shape of a cauldron down into the earth. Above as wide as a good rifle shot, but below quite narrow. And there underneath there are many holes where the ice remains through the whole summer. From such ice have Duke Frederick Graf and Duke von Gallenberg daily made use in summer to cool their wine. Six years ago I descended there in the month of August, and found ice enough in all the holes."

In the same volume Freiherr Valvasor elaborates his remarks about this cave and that at Latzenberg, repeating in the main the observations in the paragraph just given. He says: "There hang also long icicles which are quite pleasant to look at. * * * This ice breaks all too easily and quickly. * * * Contrarywise, however, this ice lasts much longer in the sun and the heat than other ice. * * * Some might think it would eventually turn into stone: this, however, does not happen: for it remains only in summer and disappears in winter: as I can say for certain, as I have been in myself in the winter as well as in the summer time. * * * For as in the summer the floor is quite covered with ice: it makes walking so dangerous and bad that one cannot take a step without climbing irons; but in the winter time one goes safely and well. * * *"

Freiherr Valvasor was evidently an accurate observer, and, if for his word "winter" we substitute "autumn," his account will be much more nearly correct than might have been expected two centuries ago.

The Kuntschner Eishöhle. (Petruzzi in Haidinger's _Berichte_, etc., vol. VII., pages 65, 66.)--This is known also as the Töplitzer, Unterwarmberger or Ainödter Grotto. It lies 2 kilometers from Kuntschen, and 12 kilometers from Töplitz near Neustädtel, in the Krain. Altitude about 630 meters. Petruzzi says: "Of all so far noticed ice grottoes it is the most wonderful and splendid." In August and September, 1849, the temperatures near the ice were about two degrees above freezing. On the 16th of August, there were many long ice stalagmites and stalactites; on the 29th of September they had diminished materially. Petruzzi says also: "One leaves the abundant vegetation of the Alpine summer flora, and through bushes and dwarf underbrush, through bare and half moss covered rocks and débris, through rotten and twisted tree stems, one comes to the hall of eternal winter, where the microscopic mosses of the north surround the thousand year old stalactites, hanging from the dripping vault, with an always passing, always freshly forming, tender sulphur colored down." Dr. Schwalbe has also examined this cave.

II., 1896, pages 72-74.)--This glacière is on the south side of Siljak, near the village Muzinac. A passage 60 meters long leads to a hall about 10 meters in height. Dr. Boué found snow here in August, the thermometer standing below freezing point. The people in the neighborhood told Dr. Boué that the snow is formed in June and disappears in September and that it is sometimes carried to Nisch. He also heard of similar cavities on the Bannat Mountain. Dr. Cvijic observed in the hall a temperature of +0.4° C.

Cave of Skerizora. (Karl F. Peters, _Sitzungsbericht der K. K. Akademie der Wissenchaften_, Wien, vol. XLIII., 1861, page 437; Bielz, _Siebenbürgen_, 1885, page 37.)--This is one of the greatest glacière caves known. It lies in the Bihar Mountains, three hours from the village of Ober-Girda, which can be reached from Gyula Fehérvar, via Topánfalva. It is a pit cave, in limestone, at an altitude of 1127 meters. The pit is about 57 meters broad, and 45 meters deep, with exceedingly steep walls. The entrance is in the northeast wall and is about 10 meters high. This leads into a nearly circular hall 47 meters in diameter and about 20 meters high. The floor is ice. In the southeast corner is a hole over 75 meters deep. In the northwest wall is an opening 14 meters wide, which forms the beginning of a sort of gallery 54 meters long and which at its further end is 24 meters wide and 8 meters high. This is also covered with a flooring of ice, which in some places can only be descended by step cutting. This passage is also richly adorned with ice stalactites and stalagmites. At its end is another also nearly circular hall, 21 meters in diameter and about 22 meters high. This is called the '_Beszerika_' or church. In one place there is a magnificent collection of ice stalagmites called the "Altar." Peters found in dirt on the sides of the cave remains of bats not very different from those now living in the vicinity. He thinks the bats may have come there before the cave became a glacière; or else that they may even now sometimes get into the first hall and there perish from cold. This makes it uncertain, therefore, whether the remains can be considered as of the past or the present.

Eishöhle bei Roth.--Described in Part I., page 35.

Mines on the Eisenberg. (Fugger, _Eishöhlen_, page 59.)--These lie near Blankenburg in the Thüringer Wald and have been known to contain ice.

(Behrens, _Hercynia Curiosa_, pages 68, 70.)--These lie near Questenberg in the Southern Harz Mountains, at an altitude of about 300 meters. The Grosses Loch is described as a sort of small pit some 8 meters deep, in one side of which opens a small fissure some 10 meters long. Ice has been found in this in April; Schwalbe found none there in July. The Kleines Loch was another small cold cave near the Ziegenloch, but it has been filled up. Behrens says that the dampness at the cave at Questenberg is precipitated as snow.

Professor Pleischl, in May, 1834, found ice under the rocks a little distance from the surface. The surface of the rocks was then warm. On the 21st of January, 1838, Professor Pleischl found snow on the outside of the rocks, but no ice underneath. He was assured by the people of the district that the hotter the summer, the more ice is found.

Glacière on the Zinkenstein. (Pleischl, in Poggendorff's _Annalen der Physik und Chemie_, vol. LIV., 1841, page 299).--The Zinkenstein is one of the highest points of the Vierzehnberge, in the Leitmeritz Kreis. There is a deep cleft in basalt, where ice has been found in summer.

Dóbsina Jegbarlang. Described in Part I., page 13. (Pelech; _The Valley of Stracena and the Dobschau Ice Cavern_; Schwalbe, _Über Eishöhlen und Eislöcher_, page 31.)--Pelech gives the following measurements: The Grosser Saal is 120 meters long, 35 meters to 60 meters wide, and 10 meters to 11 meters high, with a surface area of 4644 square meters. The ice mass is estimated as 125,000 cubic meters in volume. The length of the Korridor is 200 meters; the left wing being 80 meters, and the right wing 120 meters long. The cave was first entered on July 15th, 1870, by Herr Eugene Ruffiny, of Dóbsina, and some friends. He had happened to fire a gun in front of it, and hearing a continuous muffled rolling echo within, determined to explore it.

Dr. Schwalbe quotes the following series of observations in Dóbsina during the year 1881:

DEEPEST POINT FROM KORRIDOR ENTRANCE. GROSSER SAAL. OF KORRIDOR. TO KLEINEN SAAL.

January -2.2° -4.2° -2.2° -0.6° February -1.2° -3.4° -1.9° -0.3° March -1.4° -2.1° -0.9° -0.2° April -0.25° -1.25° -0.7° +0.3° May +0.7° +0.9° -0.5° +0.5° June +1.0° +1.5° -0.5° +0.5° July +1.8° +2.1° +0.2° +1.1° August +3.4° +3.8° +0.24° +0.80 September +2.00 +2.3° -0.3° -0.15° October -0.2° +0.2° -0.5° -0.2° November -1.3° -1.9° -0.6° -0.3° December -2.2° -3.2° -0.65° -1.75° ------ ------ ------ ------ Year +0.04° -0.44° -0.69° -0.02°

The Philadelphia _Evening Bulletin_, March, 1st, 1899, printed the following note about Dóbsina: "In this cave, some sixteen years ago, a couple named Kolcsey elected to pass the week immediately following their marriage. They took with them a plentiful supply of rugs, blankets and warm clothing, but notwithstanding all precautions, their experience was not of a sufficiently pleasant nature to tempt imitators."

Lednica of Szilize. (M. Bel, _Philosophical Transactions_, London, 1739, vol. XLI., page 41 _et seq._; Townson, _Travels in Hungary_, 1797; Terlanday, _Petermann's Mittheilungen_, 1893, page 283.)--It lies 1.5 kilometers from the village of Szilize, near Rosenau, in Gomör County, in the Carpathians, at an altitude of 460 meters. A pit about 35 meters deep, 75 meters long, and 48 meters wide opens in the ground, and at the southern end, in the perpendicular wall, is the cave. The entrance is 22 meters wide, 15 meters high, and faces north. A slope 4 meters long sinks with an angle of 35° to the floor of the cave, which is nearly circular in form, with a diameter of about 10 meters. On the east side of the cave there seems to be a hole in the ice some 10 meters deep.

In 1739, there was published in London a curious letter in Latin from Matthias Bel, a Hungarian _savant_, about the cavern of Szilize. He says: "The nature of the cave has this of remarkable, that, when outside the winter freezes strongest, inside the air is balmy: but it is cold, even icy, when the sun shines warmest. As soon as the snow melts and spring begins, the inner roof of the cave, where the midday sun strikes the outside, begins to sweat clear water, which drops down here and there; through the power of the inner cold it turns to transparent ice and forms icicles, which in thickness equal large barrels and take wonderful shapes. What as water drops from the icicles to the sandy floor, freezes up, even quicker, than one would think.

"The icy nature of the cave lasts through the whole summer, and what is most remarkable, it increases with the increasing heat of the sun. In the beginning of the spring the soft winter's warmth begins to give way soon thereafter, and when spring is more advanced, the cold sets in, and in such a manner, that the warmer does the (outside) air grow, the more does the cave cool off. And when the summer has begun and the dog days glow, everything within goes into icy winter. Then do the drops of water pouring from the roof of the cave change into ice, and with such rapidity that where to-day delicate icicles are visible, to-morrow masses and lumps, which fall to the ground, appear. Here and there, where the water drips down the walls of the cave, one sees wonderful incrustations, like an artificial carpeting. The rest of the water remains hanging on the ice, according to the warmth of the day. For when for a longer time it is warmer, the ice of the stalactites, of the walls and of the floor increases; but when the ruling heat, as sometimes happens, is diminished through north winds or rainstorm, the waters freeze more slowly, the ice drips more fully and begins to form little brooklets. When however the temperature gets warmer, the icy nature of the cave begins once more. Some have observed, that the nature of the grotto receives the changes of temperature ahead, like a barometer. For, when a warmer temperature sets in outside, the waters change into ice, several hours before the heat sets in, while the opposite takes place, when by day the temperature is colder; for then even by the warmest sky the ice begins to melt noticeably.

"When the dog days have passed and the summer has already changed into fall, the cave with its own nature follows the conditions of the external air. In the early months and while the nights are growing colder, the ice diminishes visibly; then when the air cools off more and more and when the brooks and side are rigid with frost, it begins to melt as though there was a fire built underneath, until, when winter reigns, it is entirely dry in the cave, without a sign of ice being left behind. Then gentle warmth spreads into the entire cave, and this icy grave becomes a safety resort for insects and other small animals, which bear the winter with difficulty. But besides swarms of flies and gnats, troops of bats and scores of owls, hares and foxes take up their abode here, until with the beginning of spring, the cave once more assumes its icy appearance."

These assertions of Bel are the most inaccurate ones made about glacières. Yet, strange to say, they have colored the literature of the subject down to our own times; and have been repeated many times, sometimes with, sometimes without, the hares and foxes; the latest repetition seeming to occur in 1883.

Basins or Troughs Retaining Ice. (Dittmar, _Ueber die Eismülden im Östlichen Siberien_; Middendorff, _Zusatz_; _Bulletin de la classe physico-mathématique de l'Académie Impériale des Sciences de St. Pétersbourg_, 1853, vol. XI., pages 305-316.)--These troughs are nearly akin to gorges and gullies, but their water supply seems to come from a cause which is not usually present in gorges. Their principal observer, M. de Dittmar, thought that a cold and snowy winter would add materially to the supply of ice, but he also thought that a necessity to the existence of the ice in these troughs was an abundant water supply from a spring, whose temperature should be so high as not to freeze in winter. The cold is supplied by the winter temperatures. Some of the most important are reported--

In the Turachtach Valley.

Near Kapitanskji Sasiek.

In the valley of the River Belvi.

In the valley of the River Antscha.

In the Kintschen Valley.

In the neighborhood of Kolymsk.

In the Werchojanski Mountains.

In the Stanowáj Mountains.

KONDOOZ.

Cave of Yeermallik. (Burslem, _A peep into Toorkisthan_, 1846, chaps. X., XI.)--In the valley of the Doaub, northwest of Kabul. The entrance is half way up a hill, and is about 15 meters wide and 15 meters high. This is a large cave, with many ramifications and galleries. In the centre of a hall far within, Captain Burslem found a mass of clear ice, smooth and polished as a mirror, and in the form of a beehive, with its dome-shaped top just touching the long icicles which depended from the jagged surface of the rock. A small aperture led into the interior of this cone, whose walls were about 60 centimeters thick and which was divided into several compartments. Some distance from the entrance of this cave there is a perpendicular drop of 5 meters. A short distance beyond this, in one of the halls, were hundreds of skeletons of men, women and children, in a perfectly undisturbed state, also the prints of a naked human foot and the distinct marks of the pointed heel of an Afghan boot. The moollah, who was acting as guide, said the skeletons were the remains of seven hundred men of the Huzareh tribe who took refuge in the cave with their wives and children during the invasion of Genghis Khan, and who defended themselves so stoutly, that after trying in vain to smoke them out, the invader built them in with huge natural blocks of stone, and left them to die of hunger. Some of the Afghans said that the cave was inhabited by Sheitan, a possibility denied by the moollah who guided Captain Burslem, on the philosophical plea that the cave was too cold for such an inhabitant.

HIMÁLAYA.

Glacière Cave of Amarnath. (Miss Mary Coxe of Philadelphia showed me a copy of a letter of Dr. Wilhelmine Eger describing a visit to this cave.)--It lies three days' journey from Pailgam in Kashmere, on the borders of Little Tibet. The altitude is evidently high as one crosses snow fields to get to it. A small path zigzagging up a grassy slope leads to the cave and is a stiff climb from the valley. The cave opens on the side of a mountain and has a large, almost square mouth at least as big as the floor area within. The floor of the cave is the continuation of the grass slope and slants upwards and backwards to the back wall, the only case of the kind so far reported. This cave is most curiously connected with religion. Dr. Eger says that there are two small blocks of ice in it which never melt. From time immemorial these blocks of ice have been sacred to the Hindoos who worship them--as re-incarnations--under the names of Shiva and Ganesh. Dr. Eger saw offerings of rice and flowers on them. Thousands of pilgrims come every year at the end of July or beginning of August from all parts of India. Thousands of miles have been traversed and hundreds of lives laid down through this journey. Every year people die either before reaching the cave or after. The trip from Pailgam in Kashmere takes three days up and two days down, if one returns by a shorter route where the way is unsafe because of avalanches. So many have perished there that the pass is called "The Way of Death." This must be taken by one class of pilgrims, _Sardhas_ or Holy Men, to complete the sacred circuit, but the Hindoos say any one dying on the pass will go straight to heaven.

Icicles Formed by Radiation. (General Sir Richard Strachey, _Geographical Journal_, 1900, vol. XV., page 168.)--On the Balch pass of the Balch range in Tibet, General Strachey, in 1848, saw icicles of which he says: "On the rocks exposed to the south were very curious incrustations of ice, icicles indeed, but standing out horizontally like fingers towards the wind. I was not able to understand how they were caused, nor can I tell why they were confined to particular spots. The thermometer stood at 41°[F.], and though the dew point at the time would probably have been below 32°[F.], and the cold produced by evaporation sufficient therefore to freeze water, yet it is evident that no condensation could ever take place simultaneously with the evaporation. * * * It has since occurred to me that these icicles were formed by radiation. I found, subsequently, in a somewhat similar position, that a thermometer suspended vertically, and simply exposed to the sky in front of it, was depressed as much as 20° F. below the true temperature of the surrounding air. This result was, of course, due to the radiation through the extremely dry and rarefied atmosphere at the great elevation at which the thermometer was exposed. As radiation takes place freely from a surface of ice, the growth of such icicles as those described might be due to the condensation of vapour brought up by the southerly day winds that so constantly blow over these passes, and its accumulation in the form of ice on the exposed extremity of the icicle, the temperature of which might thus have been greatly reduced."

INDIA.

Ice Formed by Radiation. (T. A. Wise, _Nature_, vol. V., page 189; R. H. Scott, _Elementary Meteorology_, Third Ed., pages 61, 62.)--Mr. Bunford Samuel called my attention to the mode of manufacturing ice by radiation in India. It is as follows:--

"A very practical use of nocturnal radiation has been made from time immemorial in India in the preparation of ice, and on such a scale that about 10 tons of ice can be procured in a single night from twenty beds of the dimensions about to be given, when the temperature of the air is 15° or 20° [F.] above the freezing point. * * * The locality referred to is the immediate neighborhood of Calcutta. A rectangular piece of ground is marked out, lying east and west, and measuring 120 by 20 feet. This is excavated to the depth of two feet and filled with rice straw rather loosely laid, to within six inches of the surface of the ground. The ice is formed in shallow dishes of porous earthenware, and the amount of water placed in each is regulated by the amount of ice expected.

"In the cold weather, when the temperature of the air at the ice fields is under 50°, ice is formed in the dishes. The freezing is most active with N. N. W. airs, as these are driest; it ceases entirely with southerly or easterly airs, even though their temperature may be lower than that of the N. N. W. wind.

"No ice is formed if the wind is sufficiently strong to be called a breeze, for the air is not left long enough at rest, above the bed, for its temperature to fall sufficiently, by the action of radiation.

"The rice straw, being kept loose and perfectly dry, cuts off the access of heat from the surface of the ground below it, and, when the sun goes down, the straw being a powerful radiator, the temperature of the air in contact with the dishes is reduced some 20° below that prevailing some two or three feet above them. The rapid evaporation of the water into the dry air above creates also an active demand for heat to be rendered latent in the formation of steam, and the result of all these agencies is the formation of ice, under favorable circumstances, on the extensive scale above mentioned."

KOREA.

Glacière Cave on the Han Gang.--Messrs. J. Edward Farnum and George L. Farnum, of Philadelphia, inform me that they saw a small cave containing ice on the banks of one of the Korean rivers. It is about 75 kilometers from Seoul, nearly northeast, near the ferry where the old road leading from Seoul towards northern Korea crosses the Han Gang, the river which passes by Seoul. The entrance is small; perhaps 2 meters wide. The cave is not thoroughly explored. Ice lies near the entrance, and as far back as the Messrs. Farnum could see.

Glacière Lava Cave near Shoji. (_Evening Telegraph, Philadelphia, January 2d, 1896._)--The cave is about 12 kilometers from Shoji, and is in lava. First there is a pit in the forest, some 5 meters wide by 15 meters deep. The cave opens into this. It seems to be some 400 meters long and from 2 meters to 12 meters high. There is an ice floor in places, also many ice stalagmites. At the furthest point reached there is a strong air current, which extinguishes torches and so far has prevented further exploration. Ice from the cave has been cut by the country people for sale at Kofu, which is not far distant.
