[The tenacity of any fabric may be readily ascertaineda very simple apparatus. The two ends of the fabrickeing secured by clamps, the latter may be separated bya screw, placed in connection with a dynamometer or aModified application of that instrument. The degree of^tension induced by the fabric becomes thus indicated111 lbs. by the dynamometrical adaptation; and on the screwkeing urged to the breaking point, that may be alsodetermined with considerable precision. The value ofthis for such purposes as those indicated in the text isVci 7 evident.—It. E.]

Kiv. 10 ^' SC0YC ry of those auriferous deposits, which havetile TT 8Uel1 Tas * ' m P or * ance the metallic exploitations oftied • r °^ Was resu lt of accident. The miners, occu-PWo 111 accustomed searches, and who went to ex-
den . rcru °tc territories with a view of discovering newijeli e Slt3 ^ ere > ney er supposed that the soil, which was°ved to be so sterile, enclosod within its bowels more
of the precious metals than they had ever dared to hopefor, allowing even for the utmost good fortune; and thatnot only was that soil which they were quitting auriferous,but that the extraction of the metal from it would presentless difficulties than the excavations of a single quarry.I 11 the year 1774 certain repairs, effected in one of thedepartments of the mine of Klutchefsk, were the occasionof a bed of auriferous sand being discovered, one portion ofwhich was first submitted to the operation of washing in1775. This was the first operation of the kind that wasever effected in the Ural. Thirty years elapsed withoutthis preliminary attempt leading the Ural miners anyfurther in the course they had opened. Some researchesalso took place in the commencement of the presentcentury, about the years 1804, 1807, 1810, without,however, any decisive results. In 1821 the first depositof auriferous sand in the department of Goro-Blagodatwas discovered, and in 1823 a commission, nominated bythe Emperor Alexander , directed the investigation, anddrew up the regulations for working it. Erom that epochthis important branch of mining industry lias been con-stantly in a condition of progress.

[The manufacture of arms carried on at this and otherestablishments in this empire is one of great extent andimportance. Progressive improvements have been madein the quality of these weapons; and they are now of anexcellent description, so far as regards their practicalutility. The arms produced at Birmingham presentpoints of superior workmanship and finish; but it doesnot appear that for direct use they are preferable to thoseof Russian manufacture. The immense resources of ironore possessed by Russia supply the raw material in inex-haustible quantities, and the use of wood or charcoal insmelting renders the product of good quality.—R. E.]
