The handles are of brass and form part of the end links, to which they are connected by a short link and jam-nuts, by which the length of the chain is adjusted. The tallies are of brass, and have one, two, three or four notches, as they mark ten, twenty, thirty or forty links from either end. The fiftieth link is marked by a rounded tally to distinguish it from the others. In place of the four-pole chain just described, many surveyors prefer a chain two rods or thirty-three feet long, having only fifty links, which are counted by tallies from one end in a single direction. Our surveyors' chains are made of Nos. 8 and 10 refined iron wire, and of Nos. 8, 10, 12 and 15 best steel wire. Iron And Steel Steel chains are often preferred on WIRE account of their greater strength, although they are more costly than those of iron. Engineers' chains differ from surveyors' chains, in that Engineers' a unk including a ring at each end is one foot Chains long, and the wire is of steel and therefore much stronger. They are either fifty or one hundred feet long, and are furnished with swivel handles and tallies like those just described. The wire used for these chains is of steel of the first quality, Nos. 8, 10 and 12. A very light and strong chain is made of No. 12 steel Brazed Steel wire, the links and rings of which are Chains securely brazed. The wire is of a low spring-temper, and the chain, though light, is almost incapable of being broken or stretched in careful use. Our brazed steel chains have been found exceedingly desirable for all kinds of measurement, and for the use of engineers upon railroads and canals they have very generally...
