of the musket is the operation of stocking. This is done in the old arsenal-building, which, with the exception of one floor, is wholly devoted to this purpose. The wood from which the stocks are made is the black walnut. This was formerly obtained in Pennsylvania, and was kept on hand in the storehouse in large quantities for the purpose of having it properly seasoned. During the last two years, however, Ohio and Canada have furnished the greater part. The wood is sawn into a rough semblance of the musket-stock before it is sent to the armory. It then passes through seventeen different machines, emerging from the last perfectly formed and finished. A gun-stock is, perhaps, as irregular a shape as the ingenuity of man could devise, and as well calculated to bid defiance to every attempt at applying machinery to the work of fashioning it. The difficulties, however, insurmountable as they would seem, have all been overcome, and every part of the stock is formed, and every perforation, groove, cavity, and socket is cut in it, by machines that do their work with such perfection as to awaken in all who witness the process a feeling of astonishment and delight. The general principle on which this machinery operates may perhaps be made intelligible to the reader by description; but the great charm in these processes consists in the high perfection and finish of the machines, the smoothness, grace, and rapidity of their motions, and in the seemingly miraculous character of the performances which they execute. The entire action of the various machines is regulated and guided by patterns, which are models in iron of the various parts of the stock which it is intended to form. The first machine in the stocking-room cuts the sides of the stock to the proper form for turning. The second saws off the butt-end, and cuts a diagonal line at the breech. The third is armed with two circular saws, which cut the upper part of the stock to the form of the finished arm. An iron pattern of the stock is placed in the machine directly under the stock to be turned, upon which rests a guide-wheel, corresponding in size and shape to the two saws above. The whole is then made to revolve very rapidly, the guide-wheel controlling the action of the cutters, the result being an exact wooden counterpart of the iron pattern. The fourth machine forms the butt of the stock in the same manner. The next simply planes three or four places upon t
