So when Roger had packed the little heliograph instrument in as small compass as possible, in order that it might not be ungainly in the saddle, and gone to the edge of the Canyon to look over, the scene struck him with loneliness. In precisely the same place, two months before, he had stood and made up his mind to risk the peril of that single-handed journey, and his courage began to revive as he remembered how well it had resulted. Down below him he could see Bright Angel Creek, and far away, the peak to which he had signaled, all redolent of the interest of the summer now fast waning. Even the trail upon which he set out to return was full of the memories of his frontiersman friend, who had lightened the way with anecdote and information on his first journey there.
But while Roger was inly conscious of a feeling of isolation in being thus cut off from all the Survey parties, and looked forward to his ride to Needles with little anticipation, that sense was not shared by Duke, who, having twice before with Roger traversed the high Kaibab plateau, remembered well the succulent long bunch-grass, the fragrant lupine and the toothsome wild oats. For the Kaibab plateau, lying high and therefore being moister than the surrounding territory, is a veritable garden. The gently declining ravines, instead of being filled with boulders at the bottom, are decked with flowers and their bases are avenues of smooth, rich lawn; on the banks rise spruces and pines, with the white trunks and pale foliage of the quivering aspen; and on the table-land above in wild profusion grow every sort of herb and plant and flower.
The desert lies to the north, the inaccessible Canyon to the south, an alkali waste to the westward, and the desolate cactus land to the east, but the Kaibab plateau, 8,000 feet above the sea, is a sylvan paradise. Yet there is no running water, and travel over it must be well within reach of trails. Here alone, in this vast arid tract, it rains frequently, but the rains form no streams, for the whole plateau is pitted with cups or depressions ten to twenty feet across, into which the water runs, and through which by some underground passages it disappears only to swell in some invisible manner the swollen torrent of the Colorado, 6,000 feet below.
Through this plateau Roger rode slowly, enjoying its peacefulness the while. No great hurry consumed him, his present work was done, and until he reached Prescott, he was his own master. Duke, moreover, had fared ill in the hard riding of the past few weeks, and so it was by very easy stages that the boy crossed the Kaibab, and indeed, loafed one whole week in the wonderful De La Motte Park, in the midst of the plateau, to give his horse a rest and to let him fill out his bones a little on the succulent grasses. A most beautiful country to enter—and a hard one to leave. No artificial maze is more confusing, for enticing as the ravines are, they are all exactly alike, no landmarks exist by which a direction may be followed, and the valleys themselves wind and double like a frightened hare.
Roger, however, had crossed this forest the first time with the frontiersman, who knew the trails like a book, and he had learned the general lie of the country from him. Besides, the lad had imbibed enough woodcraft since his appointment on the Survey to enable him to follow a trail, no matter how faint or tortuous, a thing which even the Mormon herders who follow the mazes of the wood with a keenness equal to that of the Indians, and with more intelligence, admit is a difficult thing to do.
But idleness was in no sense a characteristic of Roger's make-up, and he was glad when he reached Stewart's Canyon, where the main trail took a direct road northwards to round the Dragon and the Little Dragon and to skirt the Virgin Range still further to the northward. But as the trail descended into the valley and the altitude became less, it was seen that Paradise was left behind. Instead of pines and aspens, the ferocious and forbidding cactus took its place. The yuccas or Spanish bayonets, the prickly pear, the gaunt Sahaura and the spiny devil, together with other truculent barbarians of the vegetable kingdom convinced the boy that he had left behind all the attractive part of his trip.
To the west, Roger quickened his pace and passed over the Shewitz plateau, crossing stretches of lava, black and recent-looking, as though they had been erupted but a few years before. Then, coming to the famous geological break in the rocks known as the Hurricane Fault, he turned sharply to the south through the plain uninteresting territory of Eastern Nevada and California and reached the Needles again with little trouble to himself or Duke. By this time Roger felt quite at home in and about the Canyon, and he was conscious of boyish pride when the proprietor of El Garces, the big hotel at the Needles, welcomed him as an old traveler.
Changing at Prescott Junction, it was not long before Roger found himself in Prescott, a thriving and flourishing town of the Southwestern type. There Roger found a large packet of mail, letters from home, notes from former school friends to whom he had written at divers times throughout his trip, and which had been sent to Washington, his field address not being known. But the letter that was first opened bore no stamp, being franked with the seal of the United States Geological Survey.
As before, there was inclosed with the letter of instructions a personal letter from Mitchon, to the effect that favorable reports had been received and implying that his next party probably would be the last before his start on the Alaskan trip. The last few words made Roger almost leap with delight, for it was evidence to him that if he continued as well as he had begun, he would be accepted by Rivers, which throughout had been the goal of his ambition.
The letter of direction, moreover, was fairly pleasing, though couched in the usual dry official terms. It was to the effect that he should join the topographical party under the leadership of Mr. Gates, present post-office address being Aragon, County Presidio, Texas, and that the party was engaged in mapping the Shafter quadrangle. Borrowing a large atlas, the boy promptly proceeded to look up Aragon and Shafter, and found, to his delight, that it was near the boundary line of Mexico.
