These dams had not been the work of men at all. Rather they were structures laid down by those curious little civil engineers, the beavers. The cottonwood trees had been felled so that the thick branches had lain across the waters, and in their own secret ways the limbs had been matted and caked until no water could pass through. True, the beavers themselves did not emerge for him to converse with. Perhaps they were busy at their under-water occupations, and possibly the trappers who sooner or later penetrate every wilderness had taken them all away. He looked along the bank for further evidence of the beavers' work. Wonderful as the dams were, he found plenty of evidence that the beavers had not always used to advantage the crafty little brains that nature has given them. They had made plenty of mistakes. But these very blunders gave Bruce enough delight almost to pay for the extra work they had occasioned. After all, he considered, human beings in their works are often just as short-sighted. For instance, he found tall trees lying rotting and out of reach, many feet back from the stream. The beavers had evidently felled them in high water, forgetting that the stream dwindled in summer and the trees would be of no use to them. They had been an industrious colony! He found short poles of cottonwood sharpened at the end, as if the little fur bearers had intended them for braces, but which--through some wilderness tragedy--had never been utilized. But Bruce was in a mood to be delighted, these early morning hours. He was on the way to Linda; a dream was about to come true. The whole adventure was of the most thrilling and joyous anticipations. He did not feel the load of his heavy suitcase. It was nothing to his magnificent young strength. And all at once he beheld an amazing change in the appearance of the stream. It had abruptly changed to a stream of melted, shimmering silver. The waters broke on the rocks with opalescent spray; the whole coloring was suggestive of the vivid tints of a Turner landscape. The waters gleamed; they danced and sparkled as they sped about the boulders of the river bed; the leaves shimmered above them. And it was all because the sun had risen at last above the mountain range and was shining down. At first Bruce could hardly believe that just sunlight could effect such a transformation. For no other reason than that he couldn't resist doing so, he left his bag on the road and crept down to the water's edge. He stood very still. It seemed to him that some one had told him, far away and long ago, that if he wished to see miracles he had only to stand very still. Not to move a muscle, so that his vivid shadow would not even waver. It is a trait possessed by all men of the wilderness, but it takes time for city men to learn it. He waited a long time. And all at once the shining surface of a deep pool below him broke with a fountain of glittering spray.
