Joe looked at him with a new thought in his eye. “Do you think so?” he said, meditatively. “Why not?” asked Harry in reply, and they continued their search. Yet they found nothing more of value among the igloos or on the tundra. It was after they had given up the search and were on their way back along the low bluff that they made a further discovery. “Harluk told about part of the village that lived in what he called a ‘kitekook.’ What sort of an igloo is that?” “That’s so,” replied Joe; “I had forgotten. Why, ‘kitekook’ is the Point Hope word for cave. We haven’t seen any caves yet. They would be in the bluff, seems to me.” For a long time they searched the bluff without finding anything. The disintegrating forces of frost and thaw each spring change the face of all Arctic cliffs. Crumbled by the frost and torn off by the water, the warm weather often brings the fronts down in little landslides. The streams gully through them and cut them away so that the face of nature often changes greatly in a single year. The low bluffs along the inlet showed many marks of this violence. By and by Joe, scrambling along the débris at the foot of the bluff, gave a shout to Harry, farther on. “Here’s a wolf’s den, or a cave, or something,” he said. “Come and see it.” The wolf’s den was a hole in the bluff, half smothered in the débris which had fallen and obscured it. There was hardly room to crawl in, but Joe managed it, while Harry waited outside in some excitement. In a moment Joe called out:— “Here,” he said in a smothered voice; “take this.” A splendid slab of whalebone was passed up through the hole. After a time Joe followed it, much besmeared with dirt, but with a radiant face. “I think we’ve made a find, this time,” he said excitedly. “That is one of the ‘kitekooks,’ and it is chock-a-block with the finest bone you ever saw.” The slab which he had passed out was, indeed, a beauty, and was worth many dollars. They proceeded with the hunt with great enthusiasm and found several other “kitekooks” well stored with bone. Joe’s eyes snapped with excitement. “There’s fifty thousand dollars’ worth of splendid bone stowed right in this cliff,” he said, “and it has been waiting for us for twenty-five years. The people who came here that summer after cleaned up what was in the other igloos, but they never found this. Probably there had been a landslide that spring and blocked the caves. The Eskimos could not be hired to come here, and only they knew about it. It’s a bonanza! Hurrah! this will pay for the loss of the Bowhead, twice over.”
