After all, we ate two grouse, instead of one, that evening, burying them under the fire, and this time letting them roast long enough so that the meat parted easily from the bones.
[CHAPTER V]
"My grandfather told me that this is one way that it was done," said Pitamakan, as taking a flake of obsidian in the palm of his left hand, he tapped it with an angular stone held in his right hand. "The other way was to heat the ice-rock in the fire, and then with a grass stem place a very small drop of water on the part to be chipped off."
We had been out after flints, and finding none, had brought back the pieces of obsidian that we had placed at the foot of the tree. Earlier in the morning, on visiting the snares, we had found a rabbit in each. They hung now in a tree near by, and it was good to see them there; the rabbit remaining from our first catch had been broiled for our breakfast.
Following my partner's example, I, too, tried to work a piece of the obsidian into an arrow-point. The result was that we spoiled much of the none too plentiful material. It would not chip where we wanted it to, and if we hit it too hard a blow it splintered.
Deciding now to try the fire-and-water method, we made for the purpose a pair of pincers of a green willow fork, and melted a handful of snow in a saucer-shaped fragment of rock. I was to do the heating of the obsidian and Pitamakan was to do the flaking. He chose a piece about an inch and a half long, a quarter of an inch thick, and nearly triangular in shape. One edge was as sharp as a razor; the other two were almost square-faced.
According to his directions, I took the fragment in the pincers by the sharp edge, so as to leave the rest free to be worked upon. Gradually exposing it to the heat, I held it for a moment over some coals freshly raked from the fire, and then held it before him, while with the end of a pine needle he laid a tiny drop of water near the lower corner, about a quarter of an inch back from the squared edge. There was a faint hiss of steam, but no apparent change in the surface of the rock. We tried it again, dropping the water in the same place. Pip! A small scale half the size of the little finger nail snapped off and left a little trough in the square edge. We both gave cries of delight; it seemed that we had hit on the right way to do the work.
A little more experimenting showed that the piece should be held slanting downward in the direction in which the flaking was to be done, for the cold water caused the rock to scale in the direction in which the drop ran. In the course of two hours the rough piece of obsidian was chipped down to a small arrow-point—one that Pitamakan's grandfather would have scorned, no doubt, but a real treasure to us.
We worked all that day making the points; when evening came we had five that were really serviceable. At sundown, the weather having cleared, we went to look at the rabbit-snares. As neither had been sprung, we moved them to a fresh place. This last storm had added a good deal to the depth of the snow; it was so much now above our knees that walking in it was hard work.
