Chapter 4

I have only time to add a few words about the percussion instruments which the military band permits to connect with the wind. Drums are, with the exception of kettle drums, indeterminate instruments, hardly, in themselves, to be regarded as musical, and yet important factors of musical and especially rhythmic effect. The kettle drum is a caldron, usually of brass or copper, covered with a vellum head bound at the edge round an iron ring, which fits the circle formed by the upper part of the metal body. Screws working on this ring tune the vellum head, or vibrating membrane as we may call it, by tightening or slackening it, so as to obtain any note of the scale within its compass. The tonic and dominant are generally required, but other notes are, in some compositions, used; even octaves have been employed. The use Beethoven made of kettle drums may be regarded among the particular manifestations of his genius. Two kettle drums may be considered among the regular constituents of the orchestra, but this number has been extended; in one remarkable instance, that of Berlioz in his Requiem, to eight pairs. According to Mr. Victor de Pontigny, whose article I am much indebted to (in Sir George Grove's dictionary) upon the drum, the relative diameters, theoretically, for a pair of kettle drums are in the proportion of 30 to 26, bass and tenor; practically the diameter of the drums at the French opera is 29 and 25¼ inches, and of the Crystal Palace band, 28 and 24¼ inches. In cavalry regiments the drums are slung so as to hang on each side of the drummers horse's neck. The best drum sticks are of whalebone, each terminating in a small wooden button covered with sponge. For the bass drum and side drum I must be content to refer to Mr. Victor de Pontigny's article, and also for the tambourine, but the Provencal tambourines I have met with have long, narrow sound bodies, and are strung with a few very coarse strings which the player sounds with a hammer. This instrument is the rhythmic bass and support to the simple galoubet, a cylindrical pipe with two holes in front and one behind, sounded by the same performer. The English pipe and tabor is a similar combination, also with one player, of such a pipe and a small drum-head tambourine. Lastly, to conclude percussion instruments, cymbals are round metal plates, consisting of an alloy of copper and tin--say 80 parts to 20--with sunk hollow centers, from which the Greek name. They are not exactly clashed together to elicit their sound, but rubbed across each other in a sliding fashion. Like the triangle, a steel rod, bent into the form indicated by the name, but open at one corner so as to make it an elastic rod, free at both ends; the object is to add to the orchestral matter luminous crashes, as it were, and dazzling points of light, when extreme brilliancy is required.

In conclusion, I must be allowed to express my obligations to Dr. W.H. Stone and Mr. Victor Mahillon, to Mr. Ebenezer Prout, Mr. Richard Shepherd Rockstro, Mr. Lavoix fils, and Dr. H. Riemann, whose writings concerning wind instruments have materially helped me; to Messrs. Boosey & Co., and to Messrs. Rudall, Carte & Co., for the loan of the instruments used in the illustrations; and also to Mr. D.J. Blaikley and Mr. Henry Carte, for valuable personal aid on the present occasion. Their kindness in reading through my manuscript--Mr. Blaikley throughout--and in offering friendly and generous criticisms; also their presence and assistance by trial of the various instruments, I cannot adequately thank them for, or sufficiently extol.

(In the course of this lecture, Mr. Henry Carte played upon a concert flute, also a B flat and a G flute, an eight-keyed flute, and a recorder. Mr. D.J. Blaikley continued the illustrations upon the oboe, bassoon, clarinet, French horn, slide trumpet, valve tenor horn, cornet à piston, B flat tenor slide trombone, B flat euphonium, B flat contrabass tuba, and B flat contrabass double slide trombone.)

HOW GAS CYLINDERS ARE MADE.

The supply of compressed gas in metal cylinders has now assumed the proportions of an important industry, more especially since it was found possible, by the Brin process, to obtain oxygen direct from the atmosphere. The industry is not exactly a new one, for carbon dioxide and nitrous oxide (the latter for the use of dentists) have been supplied in a compressed state for many years. Now, with the creation of the modern amateur photographer, who can make lantern slides, and the more general adoption of the optical lantern for the purposes of demonstration and amusement, there has arisen a demand for the limelight such as was never experienced before, and as the limelight is dependent upon the two gases, hydrogen and oxygen, for its support, these gases are now supplied in large quantities commercially. At first the gas cylinders were made of wrought iron; they were cumbrous and heavy, and the pressure of the inclosed gas was so low that a receptacle to hold only ten feet was a most unwieldy concern. But times have changed, and a cylinder of about the same size, but half the weight, is now made to hold four times the quantity of gas at the enormous initial pressure of 1,800 pounds on every square inch. This means the pressure which an ordinary locomotive boiler has to withstand multiplied by twelve. The change is due to improved methods of manufacture and to the employment of mild steel of special quality in lieu of the wrought iron previously employed. The cylinders are now made without joint or seam, and the process of manufacture is most interesting. A short time ago we had an opportunity of watching the various necessary operations involved in making these cylinders at the Birmingham works of Messrs. Taunton, Delamard & Co., by whose courtesy we were enabled to make notes of the process.

Beginning with the raw material, we were shown a disk of metal like that shown in Fig. 1, and measuring thirty inches in diameter and three-quarters of an inch in thickness. From such a "blank" a cylinder destined to hold 100 feet of compressed gas can be constructed, and the first operation is to heat the "blank" in a furnace, and afterward to stamp it into the cup-like form shown in Fig. 2. To all intents and purposes this represents the end of a finished cylinder, but it is far too bulky to form the end of one of the size indicated; indeed, it in reality contains enough metal to make the entire vessel. By a series of operations it is now heated and drawn out longer and longer, while its thickness diminishes and its diameter grows less. These operations are carried out by means of a number of hydraulic rams, which regularly decrease in size. Fig. 3 roughly represents one of these rams with the plunger ready to descend and force its way into the partially formed red hot gas cylinder, C, and further into the well, W. The plunger may be compared to a finger and the cylinder to a glove, while the well may represent a hole into which both are thrust in order to reduce the thickness of the glove. With huge tongs the cylinder, fresh from the furnace, is placed in position, but just before the plunger presses into the red hot cup, one of the workmen empties into the latter a little water, so as to partially cool the bottom and prevent its being thrust out by the powerful plunger. Oil is also used plentifully, so that as the plunger works slowly down the red hot mass, it is surrounded by smoky flames. It presently forces the cylinder into the well, and when the end of the stroke is reached, a stop piece is inserted through an opening in the upper part of the well, so as to arrest the edge of the cylinder while the reverse action of drawing out the plunger is proceeded with. Directly the finger is drawn out of the glove--in other words, immediately the plunger is raised out of the cylinder--the latter drops down below with a heavy thud, still in a red hot condition.

This operation of hot drawing is repeated again and again in rams of diminishing size until the cylinder assumes the diameter and length required. This hot drawing leaves the surface of the metal marked with longitudinal lines, not unlike the glacier scratches on a rock, albeit they are straighter and more regular. But the next operation not only obliterates these markings, and gives the metal a smooth surface like that of polished silver, but it also confers upon the material a homogeneity which it did not before possess, and without which it would never bear the pressure which it is destined to withstand when finished. This operation consists in a final application of the hydraulic ram while the metal remains perfectly cold, instead of red hot, as in the previous cases.

As the result of these various hydraulic operations, we have a perfectly formed cylinder closed at one end, and we now follow it into another department of the works, when its open end is once more brought in a furnace to a red heat. The object of this is to make the metal soft while the shoulder and neck of the vessel are formed. To accomplish this, the heated open end of the cylinder is laid horizontally upon a kind of semicircular cradle, and is held there by tongs handled by two men. Another workman places over the open end a die of the form shown in Fig. 4, and while the cylinder is slowly turned round in its cradle, two sledge hammers are brought down with frequent blows upon the die, closing in the end of the cylinder, but leaving a central hole as shown in Fig. 5. Further operations reduce the opening still more until it is closed altogether, and a projection is formed as shown at Fig. 6. This projection is now bored through, and the cylinder is ready for testing.

The cylinder is submitted to a water test, the liquid being forced in until the gauge shows a pressure of two tons to the square inch. Cylinders have been known to give way under this ordeal, but without any dangerous consequences. The metal simply rips up, making a report at the moment of fracture as loud as a gun. The wonderful strength of the metal employed may be gauged by the circumstance that the walls of the cylinder designed to hold 100 feet of gas are only five-sixteenths of an inch in thickness.

During the manufacture of the cylinder, as we have already indicated, much oil is used, and, so far as steel can be saturated with that fluid--in the popular sense--the metal is in that state. It is essential that this oil should be completely got rid of, and this is carefully done before the cylinder is charged with gas. Previous to such charging, the vessel has to be fitted with its valve. Of these valves there are three kinds, known respectively as the Brin, the Birmingham, and the Manchester. Each has its admirers, but we cannot here discuss their individual merits.

The charging of the cylinder is brought about by a powerful pump having three cylinders so arranged that the compressed contents of the first cylinder are still further compressed in the second, and still more highly in the third. The filling of a 100 ft. cylinder occupies about half an hour.--_Photographic News_.

HISTORICAL DEVELOPMENT OF THE HORSESHOE.

BY DISTRICT VETERINARIAN ZIPPELIUS, OF WURTZBURG.

_Translated by S.E. Weber, V.S.[1]_

[Footnote 1: From _Theirarztliche Mittheilungen_, organ des Vereins badischer Theirarzte, Karlsruhe, No. IV., April, 1891.--_Veterinary Archives._]

Kind, gentle steed, nobly standing, Four shoes will I put on your feet, Firm and good, that you'll be fleet, That is Donar's hammer saying.

To the woods and homeward go, Always on the straight road thro', Far from what is bad, still fleeing, That is Donar's hammer saying.

Should wounds and pain become distressing, Blood to blood shall flow, Bone to bone shall grow, That is Donar's hammer saying.

Carry the rider, true little steed, Onward to all good luck bringing; Carry him thence and back with speed, That is Donar's hammer saying.

--_Old Meresburger Song_.

The horse appeared comparatively late in the group of domestic animals. In searching the monuments of the ancients, which have furnished the foundation for our present culture, that is, of the littoral inhabitants of the Mediterranean, and of the people of Mesopotamia, we find in Egypt the first traces of the horse. But even here it appears late, on the monuments of the first ruling patricians of human origin.[2] Especially during the period of Memphis (I-X Dynasty), then under the rules of Thebes (XI-XVI Dynasty), there is no trace of the horse.

[Footnote 2: Until the time Menes, with whom historical times begin, ruled in Egypt among visionary heroes or mythological gods.]

It is first in the transition period, from the late rule of Thebes (XVII-XX Dynasty) to the so-called period of Sut (XXI-XXX Dynasty) that there appears, in the wall pictures of the Pharaohs' tombs, representations of the horse. The oldest, now known, picture of the horse is found on the walls of the tombs of Seti I. (1458-1507 B.C.) under whose reign the Israelite wandered from Egypt. The horses of the mortuary pictures are very well drawn, and have an unmistakable oriental type. There has therefore undoubtedly existed in Egypt high culture, for over 4,000 years, without representation of the horse, which was the next animal domesticated after the cat.

From this time on we find the horse frequently represented both by the vainglorious despots of Mesopotamia and on the so-called Etruscan vases, which appeared after the influence of Greek art, when, on almost every urn, horses in lively action and in various forms of bodily development, almost always of an oriental type, are to be recognized. But neither here, nor in Homer, nor in the many later representations of the horse on the Roman triumphal arches, etc., are to be found horses whose hoofs have any trace of protection. Records, which describe to us the misfortunes of armies, whose horses had run their feet sore, we find on the contrary at a very early time, as in Diodorus, regarding the cavalry of Alexander the Great, in Xenophon, regarding the retreat of the ten thousand, in Polybius, regarding the cavalry of Hannibal in Etruria, etc. It is also known that the cavalry of the linguist King of Pontus, Mithridates the Great, at times and specially at the siege of Cyzicus were delayed, in order to let the hoofs of the horses grow.

On the contrary it seems strange that of the Huns alone, whose horsemen swept over whole continents from the Asiatic highlands like a thunderstorm, such trouble had not become known either through the numerous authors of the eastern and western Roman empire or from Gallia.

Horseshoeing, very likely, was invented by different nations at about the same period during the migration of the nations, and the various kinds of new inventions were brought together in Germany only, after each had acquired a national stamp according to climate and usefulness.

In this way come from the south the thin, plate-like horseshoes, with staved rim, covering the whole hoof; from the Mongolian tribes of middle Asia the "Stolleneisen" (calk shoe); while to our northern ancestors, and indeed the Normans, must be ascribed with great probability the invention of the "Griffeneisen" (gripe shoe), especially for the protection of the toes.

All varieties of the horseshoe of southern Europe are easily distinguished from the Roman so-called "Kureisen" (cure shoe), of which several have been unearthed at various excavations and are preserved at the Romo-Germanic Museum in Mentz (Mainz), Germany. The shoes, Figs. 1 and 2, each represent thin iron plates, covering the whole hoof, which in some cases have an opening in the middle, of several centimeters in diameter.

These plates, apparently set forth to suit oriental and occidental body conformation, are either directly provided with loops or have around the outer margin a brim several centimeters high, in which rings are fastened. Through the loops or rings small ropes were drawn, and in this way the shoe was fastened to the crown of the hoof and to the pastern. Sufficient securing of the toe was wanting in all these shoes, and, on account of this, the movement of the animal with the same must have been very clumsy, and we can see from this that the ropes must have made the crown of the hoof and pastern sore in a short time. One of these shoes[3] evidently was the object of improvement, to prevent the animal from slipping as well as from friction, and we therefore find on it three iron cubes 1½ centimeters high, which were fastened corresponding to our toes and calks of to-day, and offer a very early ready proof, from our climatic and mountainous conditions, which later occur, principally in southern Germany, that this style of horseshoeing was not caused by error, but by a well founded local and national interest or want.

[Footnote 3: Not illustrated.]

Aside from the so-called "Kureisen" (cure shoe) for diseased hoofs, we find very little from the Romans on horseshoeing or hoof protection, and therefore we must observe special precautions with all their literature on the subject. It is because of this that I excuse Prof. Sittl's communication in the preface of Winckelmann's "Geschichte der Kunst in Alterthum" (History of Ancient Art), which contains a notice that Fabretti, in some raised work in Plazzo Matti, of a representation of a hunt by the Emperor Gallienus (Bartoli Admirand Ant. Tab. 24), showed that at that time horseshoes fastened by nails, the same as to-day, were used (Fabretti de Column. Traj. C. 7 pag. 225; Conf. Montlanc. Antiq. Explic. T. 4, pag. 79). This statement proves itself erroneous, because he was not aware that the foot of the horse was repaired by an inexperienced sculptor.

How then did out of this Roman cure shoe develop the horseshoeing of southern Europe?

It was to be expected, with the Roman horseshoe, that the mode of fastening became unsatisfactory and necessitated a remedy or change. An attempt of this kind has been preserved in the so-called "Asiatischen Koppeneisensole" (Asiatic cap-iron-sole) (Fig. 3), which the Hon. Mr. Lydtin at Karlsruhe had made according to a model of the Circassian Horse Tribe Shaloks, and also according to the reverse of Lycian coins (called Triguetra).

This horseshoe plate, likely originating in the twelfth century, covers the whole surface of the sole, like the Roman shoes, with the exception of the wall region, which contains a rim 1 centimeter high, and above this rises at one side toward the heel three beak-like projections, about 4 centimeters high and 1 centimeter wide at the base, being pointed above and turned down, which were fastened in the wall of the hoof, in the form of a hook.

This mode of fastening evidently was also insufficient, and so the fastening of the shoe by nails was adopted. These iron plates used for shoes were too thin to allow nails with sunken heads to be used, so only nails with blades and cubical shaped heads were applicable. These nail heads, 6 to 8 in number, which left the toe and the back part of the heel free, served at the same time to secure the horse from slipping, which the smooth plates, covering the whole hoof surface, without doubt facilitated.

Shoes of this kind, after the old Roman style, with a very strong rim bent upward, likely proved very comfortable for the purpose of protection, in the Sierras of the Pyrenean peninsula, where they seem to have been in use for a long time; for in the twelfth century we find in Spain the whole form of the Roman shoe, only fastened by nails (Figs. 4 and 5). At first the shoe seems to have been cut off at the heel end, but as apparently after being on for some time, bruises were noticed, the shoe was made longer at the heel, and this part was turned up so as to prevent them from becoming loose too soon, as both the Spanish horseshoes of this period show, and the acquisition was even later transferred to England (Fig. 7).

The shoe containing a groove (Fig. 6), which we shall see later, made its appearance in Germany in the fifteenth century. From this time, according to our present knowledge, ceases the period of the Roman horseshoe. Its influence, however, lasted a great deal longer, and has even remained until our present day.

Its successor became partly the Arabo-Turkomanic and partly the Southwest European horseshoe.

For the descendants of the Numidian light cavalry, the Roman and old Spanish horseshoe was evidently too heavy for their sandy, roadless deserts, so they made it thinner and omitted the bent-up rim, because it prevented the quick movement of the horse. For the protection of the nail heads the outer margin of the shoe was staved, so as to form a small rim on the outer surface of the shoe, thus preventing the nail heads from being worn and the shoe lost too soon.

A horseshoe of that kind is shown by Fig. 8, which was used in North Africa in the twelfth century, and became the model for all forms of horseshoes of the Mahometan tribes. Even now quite similar shoes (Fig. 9) are made south and east from the Caspian Sea, at the Amu-Darja, in Samarkand, etc., which were probably introduced under Tamerlane, the conqueror of nearly the whole of Asia Minor in the fourteenth century.

The so-called "Sarmatische" (Sarmatian) horseshoe (Figs. 10 and 11), of South Russia, shows in its form, at the same time, traces of the last named shoe, however, greatly influenced by the Mongolian shoe, the "Goldenen Horde," which at the turn of the sixteenth to the seventeenth century played havoc at the Volga and the Aral. The unusual width of the toe, and especially the lightness of the iron, reminds us of the Turkomanic horseshoe, whereas, on the contrary, the large bean-shaped holes, as well as the calks, were furnished through Mongolian influence.

The Sarmatian tribes were principally horsemen, and it is not surprising, therefore, that the coat of arms of the former kingdom of Poland in the second and third quadrate shows a silver rider in armor on a silver running horse shod with golden shoes, and that at present about 1,000 families in 25 lineages of the Polish Counts Jastrzembiec Bolesezy, the so-called "Polnische Hufeisen Adel" (Polish Horseshoe Nobility), at the same time also carried the horseshoe on their coats of arms. The silver horseshoe in a blue field appears here as a symbol of the "Herbestpfardes" (autumnal horse), to which, after the christianization of Poland, was added the golden cross. The noblemen participating in the murder of the holy Stanislaus in 1084 had to carry the horseshoe reversed on their escutcheon.

From the African and Turkomanic horseshoe, through the turning up of the toes and heels, originated later the Turkish, Grecian and Montenegrin horseshoe of the present as shown by Fig. 12.

By the Moorish invasion in Spain, the Spanish-Gothic horseshoeing was also modified, through which the shoe became smooth, staved at the margin, very broad in the toe, and turned up at toe and heel, and at a later period the old open Spanish national horseshoe (Fig. 13) was developed. As we thus see, we can in no way deny the Arabian-Turkish origin of this shoe.
