Part 17

=Climate and Acclimatization.=--In view of the rapid growth of West Indian and South American commerce and the considerable emigration to Cuba and neighboring islands, which our present relations with them will probably bring about, the following extracts from an editorial in the London Lancet are of interest: "The American nation has entered upon a new and, in a sense, imperial policy, which may be regarded as forming an epoch in its history. This brings it face to face with the problem of colonization and acclimatization--a problem which we have had to confront long ago and toward the solution of which we have ever since been slowly fighting our way by following on the lines of the best practical measures of hygiene known to us. 'The white man's burden' has proved a tragical one in its drain on the life of the young manhood of this country, notwithstanding the very large measure of success which has attended our sanitary efforts in this direction. The Americans, having taken up their burden, will, no doubt, like the practical people they are, set about their task in a practical way. The four principal factors in the production of climate, according to Buchan, are distance from the equator, height above the sea, distance from the sea, and prevailing winds. The equatorial region has the most equable climate; tropical regions have much greater variations of temperature than those near the equator, and have a hot and cold or dry and rainy season. The isothermal lines of mean temperature do not supply a graduated measure of the effects of temperature on animal life. So far as climate is concerned, no single meteorological influence appears, however, to equal the effect of temperature upon health, and its range is of more importance than its mean. The European under a tropical climate suffers from anæmia, diseases of the digestive system, especially of the liver, from malaria, dysentery, typhoid fever, and yellow fever. It is not at all easy to say, however, how much of the excess of mortality of Europeans in tropical and subtropical countries is simply attributable to climatic heat _per se_, and is consequently inevitable and not the effect of malaria, or how much of it is the direct consequence of habits of life and of the neglect of sanitary laws and of personal hygiene. As Arnould rightly said, the _habitudes alimentaires_ of the Anglo-Saxon constitute one of the stumbling-blocks to health, but by far the most important is malaria, compared with which the rest are relatively insignificant. Mr. Chamberlain was right when he said the other day that 'the man who shall successfully grapple with this foe to humanity and shall find a cure for malarial fever and shall make the tropics livable for the white man, will do more for the world and more for the British Empire than the man who adds a new province to the wide dominions of the Queen.'"

"=Picture Telegraphy.="--The following account of the new so-called picture telegraphy is from the New York Electrical World and Engineer: "The apparatus consists of a receiver and transmitter, similar in appearance and in mechanism. The picture to be transmitted is drawn on a heavy piece of metal foil, the lines of the drawing being made with an insulating ink. The foil is then secured on the circumference of a horizontal cylinder on the transmitter, the cylinder being of about the size of a typewriter rubber roller. There is a similar cylinder on the receiver, on whose surface is clamped the paper upon which the drawing is to be reproduced; over this is superposed carbon paper, which is covered in turn by a sheet of thin paper. A stylus actuated by an electro-magnet is adjusted close to the surface of the latter, and each time a current is passed through the electro-magnet the stylus is forcibly pressed against the moving surface of the cylinder, and a corresponding mark is made on the two sheets in contact with the carbon paper; the outer sheet serves merely to offer a smooth surface to the stylus and to enable the operator to see that the picture is being properly reproduced. The transmitting cylinder passes under a similar stylus, which latter closes the circuit between the receiving and transmitting ends when it rests upon the foil, and opens the circuit when it passes over the lines drawn with insulating ink, in the latter case actuating the stylus magnet at the receiving end, which leaves a mark on the paper of the receiving cylinder in the form of a line corresponding to the width of the insulation over which the transmitting stylus is passing. The stylus at each end of the line is simultaneously advanced at the end of each revolution of the cylinders by a screw of small pitch. From the description it will be seen that if the surface of the foil on the transmitting cylinder were entirely insulated the receiving stylus would merely draw a number of parallel lines on the paper corresponding to the turns of the screw, and separated a distance corresponding to the pitch of the screw and the angle through which it is turned at each operation. Four different rates of advance may be given to the stylus, corresponding to as many different angles of advance that may, by appropriate mechanism, be given to the screw. The two cylinders have synchronous motion, so that all the marks or lines on the receiving cylinder correspond to widths of insulating ink traced over on the transmitting cylinder. Synchronism is obtained as follows: Connected with both receiver and transmitter is an electric motor which, at the end of every revolution of the cylinder, raises a weight, which acts on a clock train when falling and thus gives motion to the cylinder. At the end of each revolution of the transmitting cylinder a contact is made which locks for an instant the receiving cylinder when it arrives in a position corresponding to a similar position of the transmitting cylinder. Thus it will be seen that each cylinder begins its revolution from identical positions and at the same instant, and as the clockwork of both receiver and transmitter are duplicates, approximate synchronism is maintained during a revolution. Owing to the use of carbon paper, the lines made by the receiver are of considerable width, with the consequence that the resulting picture does not have the appearance of being made up of parallel lines, as in the case of reproductions by the original Caselli picture telegraph, of which the system described is a modification. The Hummell apparatus appears to be entirely practicable, the simplicity of its synchronizing mechanism giving it a great advantage over former types of Caselli picture telegraphs. The apparatus has been worked duplex with success. In one instance, a few days ago, a picture was sent from New York to St. Louis while one was being received from the same place in New York, the latter picture in addition being received simultaneously at Boston."

=The Charges on Country Checks: an Economic Mistake.=--An article in the May issue of the Yale Review, discussing the recent adoption by the New York banks of a rule imposing a "collection charge" on all country checks handled, takes the view that the new rule is a mistake. After reviewing the history and present position of the Bank of England; calling attention to the fact that although it is a private enterprise its position is used as a governor, so to speak, of English finance; the similarity to it in position and power for good or evil of the association of banks known as the New York Clearing House is pointed out; the review goes on to say: "In the associated banks of New York, as in the Bank of England, is kept a very large part of the reserve on which the great financial transactions of a whole country are based. The system of 'reserve cities' for holding large deposit accounts of country banks, in which New York is by far the most important center, is but the recognition in the national banking law of this great fact of a central reserve, and the power of utilizing such deposits, indirectly extended by the law which allows and encourages country banks to hold a large part of their legal reserve in the form of deposits in New York, probably constitutes a much more valuable privilege than the rights of note issue enjoyed by the Bank of England. In extraordinary emergencies the parallel is even closer. Just as the Bank of England is encouraged to expect a modification of the restrictions on its right of note issue, as a means of extending its effective currency reserve in times of panic, so the New York banks, by their system of clearing-house loan certificates, are encouraged and expected to evade those provisions of our national banking laws which restrict their power of issuing notes to meet an emergency.... The exercise of this function of holding a reserve for clearing the business of the country is attended with some expense, as well as with much profit. One of the most vexatious of these expenses has been the cost of collecting country checks.... Under these circumstances they have adopted a rule imposing such charges on country checks as to compel a large part of the remittances to be made in the form of bank drafts on New York city, rather than individual checks on country banks supposed to have accounts with some New York bank. This rule will save the New York banks something like two million dollars annually. It will not prevent any solvent man from making remittances, for if he has a deposit in his local bank and his local bank has a deposit in New York he can buy a draft to send as a remittance, which will pass through the New York Clearing House without question or expense. Yet, in spite of these plausible arguments, we believe the action of the New York banks to be a mistake of very serious magnitude, an inconvenience to the public, a probable loss to deposit banking in the long run, and, worst of all, a serious blow to the cause of sound currency throughout the country. It seems to us, in short, a case where narrower duties and economics have been allowed to crowd broader ones out of sight." The review then goes on to show how great an amount of inconvenience and loss of time in the aggregate the new rule is going to cause, and finally says: "In a popular government the greatest safeguard against soft money--we may fairly say the _only_ real safeguard--is to prevent the growth of a demand for soft money. And of all the means of prevention at our command the most effective is the encouragement of the habit of paying by checks. The habit of paying by check is very general in all large business centers, and has been rapidly extending into the smaller centers, and the most serious public danger in the action of the New York banks is that it seems likely to deal a severe blow to such progress."

=La Nature's Second Scientific Excursion.=--A second scientific excursion to an interesting district of France is planned, by M. Henri de Parville, of _La Nature_, to start from Bayonne August 25th. It will spend about two weeks, following the chain of the Pyrenees from the ocean to the Mediterranean. Among objects of interest enumerated are the scenery at Biarritz, Pau, Cauterets, and Bigorre; fine architecture at Toulouse, Carcassonne, Elne, etc.; glacial phenomena and thermal waters along the whole mountain chain; manufactories, including iron works at Bouchain, woolen mills at Bigorre, cigarette factories at Perpignan, and the Arago Maritime Laboratory and the sanitarium at Banyuls. The excursion will be "personally conducted" by the eminent anthropologist and archæologist, M. E. Cartaillac. The excursion last year, to the Central Plateau and the Tarn, was an eminent success. The programme of the present one seems equally attractive. M. de Parville and his associates deserve great credit for their sagacity and enterprise in inaugurating these excursions, which now promise to become annual. We can conceive nothing more profitable and conducive to real pleasure in a vacation than the tour in the company of men having a common interest in the pursuit of knowledge of Nature and art, through such magnificent regions as that of the Pyrenees or through a country so full of natural wonders and novelties as that of last year's excursion. And it will be an incalculable advantage to be under the guidance of so eminent a student and one so familiar with the remarkable features and the antiquities of southern France as M. Cartaillac.

=The American Association Meeting.=--The forty-eighth annual meeting of the American Association for the Advancement of Science will be held at Columbus, Ohio, August 19th to 26th. The association headquarters will be in University Hall, of the Ohio State University, and the headquarters of the council will be at the Chittenden Hotel. The president of the meeting will be Prof. Edward Orton, of the Ohio State University. The vice-presidents or chairmen of sections will be: Mathematics and astronomy, Alexander Macfarlane; physics, Elihu Thomson; chemistry, F. P. Venable; mechanics and engineering, Storm Bull; geology and geography, J. F. Whiteaves; zoölogy, S. H. Gage; botany, Charles R. Barnes; anthropology, Thomas Wilson; social and economic science, Marcus Benjamin. The Permanent Secretary is L. O. Howard, Cosmos Club, Washington; General Secretary, Frederick Bedell, Cornell University; Secretary of the Council, Charles Baskerville, Chapel Hill, N. C.; Treasurer, R. S. Woodward, Columbia University, New York. The address of retiring President Putnam will be delivered Monday evening, August 21st. Saturday, August 26th, will be devoted to excursions to Fort Ancient and elsewhere. Receptions and shorter excursions will be provided at hours that will not conflict with the appointments of the association.

=The Desire for Notoriety a Cause of Crime.=--Under the title _Luccheni Redivivus_ the London Lancet gives some interesting psychological data which have been obtained since the imprisonment of Luccheni, the assassin of the Austrian Empress. Twice since his trial and conviction he has attempted suicide. Within the last few days (May 13th) his moral condition has undergone a change confirmatory in a significant degree of the diagnosis which found vanity or megalomania at the root of his crime. The cantonal juge d'instruction in an attempt to ascertain if possible his associates in the crime, visited him in his cell and approached the subject with what seemed to himself due dexterity and caution. At once the previously downcast and abject creature brightened up, his eyes sparkling with gratified self-importance. "_I giornali riparlano di me?_" (So the journals are talking of me again) he exclaimed interrogatively. The judge disclosed the object of his visit. Luccheni thereupon dallied with his interlocutor, smiling at his reminiscences of the crime, assuming airs of reticence, even indulging in self-contradiction to tease if not torment his judicial antagonist. It was learned, however, that in the preliminaries leading up to the assassination he really had accomplices; beyond this nothing new was elicited from him. The point of chief importance, however, to be observed in this account is the large part which vanity and a desire for the widespread public attention which such crimes bring about plays in reconciling the criminal to his fate, and even leading to the commission of the crime in cases where the mental balance is very unstable. Hence this class of criminals should always be tried and punished with as little publicity as possible, not only because this policy deprives the individual of a show, with himself as the center, but also because every such public trial is liable to lead to the commission of similar crimes by other mentally unsound degenerates, who are sure to attend such spectacles whenever it is possible.

=Bounties and Free Trade.=--Much discussion is going on in England over the question of bounties and the propriety of putting a tariff on those imported articles which, owing to bounties or other form of government aid at their place of manufacture, can be sold "too cheaply." The following paragraphs are taken from an article in the London Spectator: "In our opinion there can be no question between the policy of free and open market and the policy of only allowing goods to be sold here 'at the natural price of the world's market.' We hold that the maintenance of an open and unhindered market is essential to our welfare; ... that is the real principle involved, and that is the ground on which this question of bounties must be fought out. It is not Cobdenism or free trade that is involved, but that which underlies them both--the great principle of the free and open market.... We attach such immense importance to the open market because we believe not only that our internal prosperity is essentially bound up with the right, not merely of consumers, but of producers, to buy as cheaply as they can and where and how they will, but that the empire itself rests upon the preservation of a free and open market. Mr. Morley never spoke a truer word than when he insisted that Cobden and Bright and the old free traders were empire builders. That they were so and that our empire could not possibly have grown up except with the help of free trade and a market always open must be clear to all whose eyes are not blinded by that evil and foolish spirit of commercial jealousy under which a man, in order to injure his neighbor, wounds himself. Free trade made our empire possible and created what the world before had never seen, overwhelming commercial power wielded without jealousy or narrowness and based on wide and liberal ideas. How long would our colonies have tolerated the connection with us had we been forever worrying them with tariffs and excluding this or that product because it was unnaturally cheap?... As it is, we bid all men welcome in our markets and none are aggrieved.... Foreign powers may hate us for our wealth and prosperity, but not one of them would care to spoil their best market. How would the commerce of France, or Germany, or Russia get on if England were ruined and the English market destroyed? The principle of maintaining a free and open market, coupled with our moral and physical energy, and our liberal aims and aspirations have given us a great and splendid empire. Are we to risk its destruction because the sugar refiners grumble, and because the words of Cobden on another subject may possibly be interpreted to show that he would not, were he alive, have voted against the imposition of countervailing duties?"

=Forest and Animal Life of the Catskills.=--The interior region of the Catskill Mountains surrounding Kaaterskill Junction is assigned, by Dr. E. A. Means in a paper of the United States National Museum, to the Canadian faunal region, with a slight mixture of the Alleghanian in the farming lands on the banks of Schoharie Creek. A few mammals of the Upper Austral zones, however, such as the New England cottontail, the deer mouse, and the gray fox, appear to have extended their ranges into the locality by following up the clearings. Though the region is now again well wooded, only the barest tags and remnants yet remain of the splendid forests that once covered the area. All is second growth except in the rockiest gulches, whence the lumber can not be extracted, and about the rocky summits of a few mountains of the East Jewett ranges. While the original forests seem to have been of conifers, the woods are now very thoroughly mixed, and the succession of trees according to altitudes, with its strongly marked division lines, is no longer seen. Specimens of fifty-eight species of trees and shrubs have been collected and placed in the National Museum. Only ten species of mollusks, one crustacean (the common crawfish), probably a dozen fishes (the author identifies eight and mentions others), eight batrachians, two snakes, and a turtle have been found. Of mammals, thirty-five species are described as known to occur at the present time, and eight as of doubtful occurrence now.

=Geology of Block Island.=--In a study of the geology and natural history of Block Island, of which Arthur Hollick gives a summary in the Annals of the New York Academy of Sciences, the most important problem was whether the Amboy clay series was represented in the island. Of fifteen species of fossil leaves and fruit capable of identification, represented by about twenty-five specimens, at least nine were typical of the Amboy flora. Observations on dip and strike of strata tended to emphasize the fact of contortion of glacial action, the dip in all cases being toward the north, indicating that the strata had been pushed southward in a series of overthrust folds by the advancing ice front. The flora may be divided physiographically into that of the hills, the peat bogs and pond holes, the salt marshes, the sand dunes, and the salt water. Trees are rare, and such vegetation as is dependent on forestal conditions is absent. The bulk of the surface is that of a typical morainal region, with rounded hills and corresponding depressions, many of the depressions being occupied by swamps or ponds, often without any visible outlet. Running streams are few and insignificant, and permanent springs occur only in a limited number of localities. The soil is bowlder till and gravel, with sand in the dunes and beaches, and there are no outcrops of rock. The flora is morainal in its general character, except in the peat bogs and on the limited sand dunes and sea-beach areas, and has its nearest analogue in that of Montauk Point. "In fact, if we could imagine Montauk Point to be despoiled of its few remaining trees and converted into an island it would bear a striking resemblance, geologically and botanically, to Block Island." Considering the geological features of Long Island, Block Island, Martha's Vineyard, and Nantucket, and comparing their floras, we find that all except Block Island have some of the plain region remaining with them, on which a characteristic flora finds a home. Block Island has lost all its plain region and accompanying flora, and is now merely an isolated portion of the terminal moraine, with small areas of modern sand beach and dune formations, affording a home only for such species as can exist under such conditions. The island appears to have been extensively wooded before it was settled, and large stumps, together with roots and branches, are found in some of the peat bogs. The scarcity of animal life on the island is sure at once to attract the attention of the observer from the mainland. Tree-living birds are absent, but robins, bank swallows, red-winged blackbirds, and meadow larks occur with some frequency. Among mollusks, the periwinkle of the Old World, an importation or migration, is the most abundant. Frogs and spotted turtles are plentiful, and a few small striped snakes were seen by Mr. Hollick. The archæology of the island is being studied by persons specially interested in the subject.
