That night he slept in the crotch of a tree. He selected a small one, which, though less comfortable, was safer from the approach of Nagoola than a larger tree would have been. This also had he learned from Nadara. Had he paused to consider, he would have discovered that all he knew that was worth while he had had from the savage little girl whom he, from the high pinnacle of his erudition, regarded with such pity. But Waldo had not as yet learned enough to realize how very little he knew. In the morning he continued his flight, gathering his breakfast from tree and shrub as he fled. Here again was he wholly indebted to Nadara, for without her training he would have been restricted to a couple of fruits, whereas now he had a great variety of fruits, roots, berries, and nuts to choose from in safety. The stream that he had been following had now become a narrow, rushing, mountain torrent. It leaped suddenly over little precipices in wild and picturesque waterfalls; it rioted in foaming cascades; and ever it led Waldo farther into high and rugged country. The climbing was difficult and oftentimes dangerous. Waldo was surprised at the steeps he negotiated--perilous ascents from which he would have shrunk in palsied fear a few weeks earlier. Waldo was coming on. Another fact which struck him with amazement at the same time that it filled him with rejoicing, was that he no longer coughed. It was quite beyond belief, too, since never in his life had he been so exposed to cold and wet and discomfort. At home, he realized, he would long since have curled up and died had he been subjected to one-tenth the exposure that he had undergone since the great wave had lifted him bodily from the deck of the steamer to land him unceremoniously in the midst of this new life of hardships and terrors. Toward noon Waldo began to travel with less haste. He had seen or heard no evidence of pursuit. At times he stopped to look back along the trail he had passed, but though he could see the little valley below him for a considerable distance he discovered nothing to arouse alarm. Presently he realized that he was very lonely. A dozen times in as many minutes he thought of observations he would have been glad to make had there been some one with him to hear. There were queries, too, relative to this new country that he should have liked very much to propound, and it flashed upon him that in all the world there was only one whom he knew who could give him correct answers to these queries. He wondered what the girl had thought when he did not follow her into the village, and set upon Flatfoot and Korth. At the thought he found himself flushing in a most unaccountable manner. What would the girl think! Would she guess the truth? Well, what difference if she did? What was her opinion to a cultured gentleman such as Waldo Emerson Smith-Jones? But yet he found his mind constantly reverting to this unhappy speculation; it was most annoying.
