The silversmith's handbook : containing full instructions for the alloying and working of silver, including the different modes of refining and melting the metal; its solders; the preparation of imitation . use some years on the Continent previous to itsintroduction into England. The old method ofmaking wire was upon the anvil, by means of thehammer; and those who manipulated in this artwere termed wiresmiths at that period. The bestform of draw-plate consists of a piece of steelabout nine or ten inches long, one and a quarterto one and a half inch broad, and about half aninch thick, each containing a number of conicalholes of various sizes, becoming smaller in suc-cession until the last hole in the plate is reached,when another plate, corresponding in size, havingsmaller graduated holes, is employed, and the wiredrawn through it; and so on, until the proper sizehas been obtained. The drawing of stout pieces of wire is effectedvery readily by means of the draw-benph (Fig. 24),and the thinner pieces, by the application of draw-tongs (Fig. 25), held in the hands of the operator, FINE WIRE-DRAWIJNCx. »»5 and made to do service by swinging the body-backwards.

When the end of the wirehas finally passed through the draw-plate, thewhole coil is carefully removed from the drum(which is made slightly conical in form for facili-
