Fig. 7 is practically the same as Figs. 16 and 17, with this difference: the bow and thong are dispensed with and the spindle twirled between the palm of the hands, as formerly practised by the California Indians, the natives of Australia, Caroline Islands, China, Africa and India.
Many of the American Indians made friction fire in this manner. They spun the thin spindle by rolling it between the palms of their hands and as pressure was exerted the hands gradually slid down to the thick lower end of the spindle. To again get the hands to the top of the drill requires practice and skill. Personally the writer cannot claim any success with this method.
