THE MAORI MODE OF DRILLING.—In the last issue of the N.Z. Journal of Science and Technology, Mr. Eldon Best, of the Dominion Museum, contributes an article on the methods of drilling used by the Maoris. The type of drill formerly used by them was the cord drill, which was used in ancient days in India and is still employed in making the sacred fire. The pump drill and bow drill were unknown to the Maori in pre-European times. The European form of pump drill was introduced by the early European settlers. Had the Maori known the pump drill in former times, it would have been the free-bar drill used by the nations of the western Pacific. The pierced-bar form was not known in that region in ancient times, but was introduced by early European visitors and residents. Mr. Best gives three photographs showing the present use of the drill for piercing blocks of stone.
