The layman will scarcely think (hat dowels—the little round wooden pins used by the furniture and car- riage trade and a few other industries—would require the output of several 'arge factories; but such is the case. The demand for dowels runs into the millions. The modern finished dowel is a round hardwood pin, of various sizes of mathematical accuracy of diameter, with rounded or pointed ends, and is usually made with a series of parallel grooves to permit the escape of air and surplus glue in the joint made by its use. For years dowels have been turned from square stock sawed out lor the purpose. According to the American Lumberman, a new dowel-making institu- tion recently put in operation resorts to a new process of making, which provides for the utilization of what would otherwise be waste material left in the woods afier the logs are taken out or at best used for firewood. Comparatively straight grained sections of bodies or branches of maple, birch and beech are sawed into. Sawing the Butts to Length. bolts about two feet in length in the woods, following the logging operations, and transported 10 the factory. The bolts are split to convenient sizes and cross-cut on an ordinary saw table to the length of dowels desired. A machine chopper then reduces the blocks to vertical strips, eliminating the defective and cross-grained wood. These strip -are then fed to an automatic ma- chine of recent invention, which chips off a section of sufficient size to form a dowel and drives the piece of wood through a hollow knife-edged die, at the aston- ishing rate of 6,000 pieces an hour. Thus the blank for the dowel is made. These blanks are dumped from the barrels into which the machine drops them into trays, which are slid into a rack, carrying corresponding trays, and then
