A straight stick, also of hard, rough-grained wood, about 8 or 10 inches in length, about the size they usually make their arrows or larger, is provided. Both ends of this are rounded, but one end is made smooth, the other is left slightly rough. The dried pith of some kind of reed, or more probably of the yucca, some fibers of the same loosely prepared like hackled flax, some powdered charcoal, I think formed by charring the yucca, and a piece of hard thick leather similar to sole leather, completes the outfit, which is carried in a leather bag made for the purpose. The first described piece of wood is placed upon the knees of the operator with a quantity of the fibrous substance beneath it which has been powdered with charcoal dust; some of the latter is put into one of the holes and the rough end of the stick inserted, the other end is put into an indentation of the leather placed under the chin, so that a gentle pressure may be exerted. The spindle is then rapidly revolved by rolling it one way and the other between the hands. The friction thus produced by the rubbing of the roughened surfaces ignites the fine coal dust, which, dropping as sparks of fire through the orifice at the bottom of the hole, falls into the dry fibrous preparation, thus igniting that, then by the breath blowing upon it a flame is produced and communicated to some fine dry wood and a fire is soon obtained. The whole operation occupies but a few minutes. [Illustration: Fig. 16. Fire-making Set. (Cat. No. 15396. U. S. N. M. Natives of Talamanca, Costa Rica. Collected by Prof. W. M. Gabb.)] One of the rudest fire-making appliances in the Museum was collected by Prof. W. M. Gabb, at Talamanca, Costa Rica. The hearth is a rude billet of charred, black wood, resembling mahogany. It has central holes, with no gutter usually, though sometimes a shallow notch is cut on both sides of the fire-hole. The drill is a light branch, rather crooked, but dressed down roughly with a knife. Another hearth is of partly decayed, worm-eaten wood; with this a hard wood drill can be used, the hearth wasting away instead of the drill (fig. 16.) The absence of any fire slot, that is, the use of the central fire-hole, is worthy of notice in this locality. I have only observed its use in various parts of the Eskimo area, from East Greenland to Kadiak; outside of this range I have not noticed it anywhere else among the present tribes of the world. From descriptions given it seems to have been practiced by the Caranchua Indians, a recently extinct tribe in Texas and Mexico. (See below.)
