As for the man, he looked down upon the girl delightedly. His pulse beat fast. He put his arm about her and together they entered the cave. There was a marriage but no ceremony. Just as robins mate when they have met or as the buck and doe, so faithful man and wife became these two. Darkness fell, the fire at the cave entrance flashed up fiercely and Ab and Lightfoot were "at home." CHAPTER XXII. THE HONEYMOON. The sun shone brilliantly, birds were singing and the balsam firs gave forth their morning incense as Ab and Lightfoot issued from their cave. They had eaten heartily, and came out buoyant and delighted with the world which was theirs. The chattering of the waterfowl along the river reached their ears faintly, the leaves were moved by a gentle breeze, there was a hum of insects in the air and the very pulse of living could be felt. Ab carried his new weapon proudly, hungering for the love and admiration of this girl of his, and eager to show her its powers and to exhibit his own skill. At his back hung his quiver of mammoth bone. His bow, unstrung, was in his hand. In front of the cave was a bare area of many yards in extent, then came a few scattering trees and, at a distance of perhaps two hundred yards, the forest began. Across the open space of ground, with its great mass of branches crushed together not far from the cave's mouth, had fallen one of the gigantic conifers' of the time, and was there gradually decaying, its huge limbs and bole, disintegrating, and dry as punk, affording, close at hand, a vast fuel supply, the exceptional value of which Ab had recognized when making his selection of a home. Near the edge of the little clearing made by nature, Ab seated himself upon a log, and drawing Lightfoot down to a seat beside him, began enthusiastically to make clear the marvels of the weapon he had devised and which he and Old Mok had developed into something startling in its possibilities.
