They passed through the gates of the foot-hills, following the stream up among them. The outstretching fences and the widely trodden dust were no more. Now and then they rose again into view of the fields and houses down in the plain below. But as the sum of the miles and hours grew, they were glad to see the road less worn with travel, and the traces of men passing from sight. The ploughed and planted country, that quilt of many-colored harvests which they had watched yesterday, lay in another world from this where they rode now. No hand but nature’s had sown these crops of yellow flowers, these willow thickets and tall cottonwoods. Somewhere in a passage of red rocks the last sign of wagon wheels was lost, and after this the trail became a wild mountain trail. But it was still the warm air of the plains, bearing the sage-brush odor and not the pine, that they breathed; nor did any forest yet cloak the shapes of the tawny hills among which they were ascending. Twice the steepness loosened the pack ropes, and he jumped down to tighten them, lest the horses should get sore backs. And twice the stream that they followed went into deep canyons, so that for a while they parted from it. When they came back to its margin for the second time, he bade her notice how its water had become at last wholly clear. To her it had seemed clear enough all along, even in the plain above the town. But now she saw that it flowed lustrously with flashes; and she knew the soil had changed to mountain soil. Lower down, the water had carried the slightest cloud of alkali, and this had dulled the keen edge of its transparence. Full solitude was around them now, so that their words grew scarce, and when they spoke it was with low voices. They began to pass nooks and points favorable for camping, with wood and water at hand, and pasture for the horses. More than once as they reached such places, she thought he must surely stop; but still he rode on in advance of her (for the trail was narrow) until, when she was not thinking of it, he drew rein and pointed. “What?” she asked timidly. “The pines,” he answered. She looked, and saw the island, and the water folding it with ripples and with smooth spaces. The sun was throwing upon the pine boughs a light of deepening red gold, and the shadow of the fishing rock lay over a little bay of quiet water and sandy shore. In this forerunning glow of the sunset, the pasture spread like emerald; for the dry touch of summer had not yet come near it. He pointed upward to the high mountains which they had approached, and showed her where the stream led into their first unfoldings. “To-morrow we shall be among them,” said he. “Then,” she murmured to him, “to-night is here?” He nodded for answer, and she gazed at the island and understood why he had not stopped before; nothing they had passed had been so lovely as this place.
