It will be seen from these references given that the Sioux used the customary Indian method. Later, they may have used the bow to expedite the drill when the wood was intractable. The bow may have been borrowed from more northern tribes, the Algonquians are said to use it;[20] Mr. Thomas C. Battey says that the Sac-Fox Indians (Algonquian stock) used a soft wood drill and a hard wood hearth. “The drill was worked by a bow and the fire caught on the end of the drill and touched to tinder.” Throughout South America the art of fire-making with two sticks of wood is found to be as thoroughly diffused as it is in North America. Many of the tribes still use it; we may say that in all tribes the use of flint and steel was preceded by that of the sticks of wood. The Guanchos, a mixed tribe of herders on the Pampas of Venezuela, practice a peculiar way of fire-getting. They select a pliant rod, place one end against the breast and the other against the block forming the hearth, _held on a line with the breast_. By pressing against the rod it is bent and turned rapidly around like an auger. This impracticable and no doubt very local method is described by Prof. E. B. Tylor.[21] In Brazil, in the Province of Goyaz, the Chavantes, Cayapós, and Angaytés, use the simple fire drill.[22] The Angaytés drill figured looks somewhat like that of the Mokis. It is usually 28^cm. long for the hearth, and for the drill 20^cm. They use the throat skin of the Nandu, _Rhea Americana_, for a tinder sack. The Lenguas of the same province use a strike-a-light consisting of a tinder horn, flint, and steel, which is also figured in the cited report. This set is very interesting, because from it, we can say with certainty where the Lengua got it. The steel is the English “flourish,” and the flint is the oval, old English shape, probably broken somewhat by blows. The Lenguas, being on the line of travel, have adopted the method from English traders. In Rio Janeiro the Indians had an angular recess at the back of their snuff mills for the purpose of making fire by friction.[23] The Ainos of Japan formerly used fire-sticks, and are said even yet to resort to this method when they have no other means of getting fire. They use also flint and steel, adopted from the Japanese. A specimen (No. 22257) is figured and described on page 583 of this paper. The fire-sticks of the Ainos of Yezo (No. 129970, fig. 17) were loaned to the Museum by Prof. F. W. Putnam, who also secured the following letter of Mr. D. P. Penhallow, who collected the sticks:
