[chap. Another group of revolving tools and machines beginswith the drill. The simplest mode of twirling the boring-stick between the hands is to be seen in fire-making (). In this clumsy way rude tribes know how to boreholes through hard stone by patiently twirling a reed orstick with sharp sand and water. This primitive tool wasimproved both for making fire and boring holes, by winding. Fig. 63.—Hebrides women grlndinjj with the quern or hand-mill (after Pennant). round the stick a thong or cord, which by being pulledbackward and forward worked the drill, as the ancient ship-wrights boring their timbers are described in the Odyssey(ix. 384). The ingenious plan of using a bow with its stringto drive the drill, so that one man can manage it, was alreadyknown in the old Egyptian workshops, but the still moreperfect Archimedean diill is modern.

To those who haveonly seen the lathe in its improved modern forms this maynot be clear, but it is seen by looking at the old-fashionedpole-lathe with which the turner used to shape his woodenbowls and chair-legs, which were made to revolve by a cordpulled up and down, on somewhat the same principle as theHomeric drill.
