close to him. But at that time the Milanese certainly had no cause to offend the Greek emperor, with whom they were in alliance; and Giulini has proved, in a very satisfactory manner, that the Milanese erected this image to ridicule the emperor Frederick I., who was their bitterest enemy1. On another image at Milan, cut out in stone, of the thirteenth century, which represents the emperor of Germany on his throne, surrounded by the electors, the latter have small mantles, which are ornamented with triangular patches of fur of the same kindo.

[Since the discovery and settlement of Canada, furs or peltries have mostly been obtained from the northern parts of America, some from the states of Rio de la Plata, a few from Germany, Holland, &c.

The success obtained by the French after their settlement in Canada in 1608, induced the formation of the English Hudson's Bay Company, which was chartered by Charles II. in 1670, with the exclusive privilege of trading with the Indians in the vast territories adjoining Hudson's Bay. But their charter never having been confirmed by parliament, hunting in those regions was still considered as open to all British subjects, and many engaged in it. In 1766, private adventurers began to traffic from Michillimakinac, whose success incited others to follow their example; and independent traders gradually spread over every part of the country, until 1787, when these scattered parties were united into one great body, under the name of the "North-west Company." The rivalry of these associations had the effect of inspiriting and extending the trade, and led to constant and furious disturbances between the two. At length, in 1821, the two concerns united, under the title of the "Hudson's Bay Fur Company," with much advantage to the peace of the fur countries, and perhaps to the permanent interests of the trade. The skins collected by this company are all shipped to London, mostly from their factories of York Fort and Moose Fort in Hudson's Bay; others from Fort Vancouver, on the river Columbia, and from Montreal.

On the part of the United States, the fur trade is chiefly prosecuted by the North American Fur Company, whose principal establishment is at Michillimakinac, where it re1 Giulini, Mem. della Città di Milano, vi. p. 407. 2 Ib., viii. p. 443.

ceives skins from the posts depending on that station and from those on the Mississippi, Missouri and Yellowstone rivers, and the great range of country extending thence to the Rocky Mountains. Of other associations in the United States, the most celebrated are Ashley's Company from St. Louis, and Captain Bonneville's, formed at New York in 1831; which last has pushed its enterprises into tracts between the Rocky Mountains and the coasts of Monterrey and Upper California. Indeed the whole of the districts from the Mississippi to the Pacific, and from the Arctic Sea to the Gulf of Mexico, are now traversed in every direction by the hunter. Almost all the American furs which do not belong to the Hudson's Bay Company find their way to New York, where they are either distributed for home consumption, or exported chiefly to London.

The fur trade is also extensively pursued by the Russians in the north of Asia and the north-west coast of America. Their chief association is the Russian American Company of Moscow; and the principal markets for their furs are the fairs of Kiachta, Novgorod and Leipsic.

London is the principal emporium of the fur trade: the vessels of the Hudson's Bay Company arrive here about September; the public sales are held in March, and are attended by a great many foreign merchants, whose purchases are chiefly sent to the great fairs of Leipsic, whence they are distributed to various parts of the continent.]

STEEL.

STEEL is a carburet of iron, and possesses some remarkable properties, by which it is distinguished from common iron. It is of such a superior degree of hardness, that it is capable of filing the latter; it strikes fire with siliceous stones, and scratches the hardest glass; it is heavier, emits a stronger sound, exhibits on fracture a finer grain, assumes a brighter white lustre when polished, is susceptible of greater elasticity; becomes more slowly magnetic, but retains that power longer; does not so easily acquire rust; in the fire it assumes various strong tints, and when heated is speedily cooled in cold water, but is then harder, more brittle and less pliable. In consequence of these qualities it is fit for many uses to which common iron either cannot be applied, or is less proper.

It is certain that the invention of steel is of very great antiquity. In the Old Testament, however, the mention of it is very doubtful, according to Professor Tychsen, whose remarks on this subject I subjoin in a note below1; but it appears that it was used as early as the time of Homer, and that the Greeks gave to it different names, one of the most common of which was stomoma, though it seems certain that this word did not so much denote steel itself as the steeled part of an instrument, or the operation of steeling. The name chalybs was given to steel from the Chalybes, a people on the southern shore of the Pontus Euxinus, between Colchis and Paphlagonia, who had considerable mines, and in particular iron and steel works: though others, on the contrary, derive the name of the people from the principal article of their commerce. This derivation appears the more probable, as Justin says that a river of Spain, on which there were steel works, was named Chalybs, but at a much later period. Some also have ascribed to the Chalybes the invention of iron, which however is much older.

1 In regard to the hardening of iron and the quenching of it in water, nothing, as far as I know, occurs in the Hebrew text of the Scriptures. The passages where it seems to be mentioned are, Isaiah, chap. xliv. ver. 12.

"The smith bends the iron, works it in a fire of coals, and forms it with the hammer; he labours on it with a strong arm," &c. according to the translation of Michaelis. It may indeed be translated otherwise, but it certainly alludes to the formation of an image of metal. The words, chap. liv. ver. 16, are still more general.

Iron, barzel, often occurs, and in some passages indeed steel may be understood under this name; for example, in Ezekiel, chap. xxvii. ver. 19, ferrum fabrefactum, or, according to Michaelis and others, sabre blades from Usal (Sanaa in Yemen). A pretty clear indication of steel is given in Jeremiah, chap. xv. ver. 12: "Iron from the north," which is described there as the hardest. To the north of Judæa was situated Chalybia, the ancient country of steel. It appears that the Hebrews had no particular name for steel, which they perhaps comprehended under the term barzel, or distinguished it only by the epithet Northern, especially as the later Jews have for it no other name than אסטמאistoma, which however is nothing else than the Greek στόμωμα, and signifies rather steeling or hardening.

Chalamisch is certainly a hard kind of stone; granite or porphyry, according to Michaelis, who treats expressly of it in Supplem. ad Lex. Hebr. N. 740.

But it seems to be less known that adamas also at first denoted steel. This is expressly said by Hesychius, and many epithets derived from adamas are applied to articles made of steel or of iron. Among these may be mentioned the helmet of Hercules, in Hesiod1, and the so-called adamantine chains, gates, and bars of the poets, which in dictionaries are always explained as consisting of precious stones.

It was not till a late period that this word was applied to the most costly of all the precious stones. In this sense it occurs neither in Homer, Hesiod, Herodotus, Orpheus, nor Dioscorides, though the first of these writers often describes various kinds of valuable ornaments. Goguet and others thence conclude that the diamond was not then known. At present I cannot enter into the history of this stone; but I must own, that I consider the knowledge of it to be older, and suspect that it was first introduced under another name, and is mentioned by Orpheus and some others under that of jasper (jaspis). This poet compares his jaspis to rock crystal, and says that it kindles fire in the same manner. That he knew how to use rock crystal as a burning-glass, he expressly tells us himself; but he certainly could not procure a diamond of such a size as to be able to burn with it. From its vitreous nature however he conjectured, and very properly, that it might be employed for that purpose. He calls the jaspis transparent, compares it to glass, and says that it had that sky colour which at present is named color hyalinus. This is probably the reason why Dioscorides and others call some kinds of jasper transparent and sky-coloured. The jaspis in the Revelation of St. John, described as a costly transparent crystalline kind of stone, was perhaps our diamond, which afterwards was everywhere distinguished by that name.

The Romans borrowed from the Greeks the word chalybs; and in consequence of a passage in Pliny, many believe that they gave also to steel the name of acies, from which the Italians made their acciajo, and the French their acier. The word acies, however, denoted properly the steeled or cutting part only of an instrument. From this, in later times, was formed aciarium, for the steel which gave the instrument its sharpness, and also aciare to steel1.

• Lib. xxxiv. sect. 41. p. 666. "Stricturæ vocantur hæ omnes, quod non in aliis metallis a stringenda acie vocabulo imposito. Et fornacum maxima differentia est; nucleus quidem ferri excoquitur in his ad indurandam aciem; aliquæ modo ad densandas incudes, malleorumve rostra." According to my opinion, stricture was the name given to pieces of steel completely manufactured and brought to that state which rendered them fit for commerce. At present steel comes from Biscay in cakes, from other places in bars, and both these formerly were called stricture, because they were employed chiefly for giving sharpness to instruments or tools, that is, for steeling them. In speaking of other metals, Pliny says that the finished productions at the works were not called stricture (this was the case, for example, with copper), though sharpness could be given to instruments with other metals also. The words of Pliny last quoted are read different ways, and still remain obscure. I conjecture that he meant to say that some steel works produced things which were entirely of steel, and that others were employed only in steeling. I shall here remark that the stricture ferri remind us of the strigiles auri: such was the name given to native pieces of gold, which without being smelted were used in commerce. Plin. xxxiii. 3. p. 616.

At present there are two methods of making steel; the first of which is by fusion either from iron-stone or raw iron, and the second by cementation. I have never found in the works of the ancients any traces of steel prepared by cementation; nor am I acquainted with the antiquity of that process, though the ancients, without knowing it, employed it for brass. Spielman says, that Pliny in one part calls it tostio; but this word occurs neither in Pliny nor in any ancient writer. It is however possible that the word torrere may somewhere signify cementation, but I have not yet met with an instance of it.

The preparation however by fusion, as practised by the Chalybes, has been twice described by Aristotle; but as I have already given in another work everything I was able to collect towards an explanation of these passages, I shall not here repeat it. I shall only remark, that the steel of the ancients, in consequence of not being cemented, suffered it
