As summer advanced, a new working schedule that precluded labor in the middle of the day was inaugurated. The more intense the heat grew, the more intense, it seemed to Roger, grew the weird beauty of the desert. The midnight stars seemed hardly to have blossomed before dawn turned the desert world to a delicate transparent yellow, deepening at the zenith to blue and on the desert floor to orange. As the sun rose, the yellow changed suddenly to scarlet and for a few moments earth and sky quivered in a lambent red fire. When the sun had shot clear of the mountains, details of landscape and contrasts of color were accented. Clear black of peaks, crimson of canyons, purple of rifts in the ranges, bright moss green of cactus dots on the yellow desert floor. And always to the west that far melting loveliness of blue and gold and black that was the River Range. And always the quivering, parching air that burned against the body like a furnace blast.
Ernest felt the heat more than Roger did and lost weight. But though he complained a great deal he stuck to his work manfully.
After Ernest and Gustav had returned from Archer's Springs and the ravages caused by the desert storm had been repaired, Roger started on a hunt into the ranges for more window glass. He dared spend his money for nothing but food.
He outfitted for a three day trip, carrying a blanket, the two-gallon canteen, beans, canned pears and a batch of baking powder biscuits. Dick gave him minute directions as to the location of different mines and of springs, and Roger started off confidently.
There was very little glass left in the Goodloe mines where Roger had located the oil. But Dick knew of mines some ten miles north along the backbone of the ranges and these Roger had as an objective when he left the camp in the yellow dawn.
He reached the Goodloe district by mid-morning. There was no trail to the north but he jogged along all the afternoon by compass and sun, keeping to the top of the ridge whenever possible. During all this time he saw no sign of human habitation. Indeed the only living beings he beheld that day were two buzzards circling meditatively over a distant peak and a lonely coyote skulking against the sky on a neighboring ridge. By six o'clock he was tired beyond expression and he had lost all idea of the number of miles he had covered, so tortuous had been the seemingly direct line of the ridge.
Roger was in no wise discomfitted or discouraged, however. He made his camp in a little sandy draw on the side of the ridge which was full of stunted cedars. He cut up one cedar for his fire and drew on the others for sufficient twigs to cushion his blanket bed, then in spite of the heat he slept the sleep that belongs to the open.
He was on his way at daylight, whistling cheerfully into the vast distances that unrolled about him. Mid-morning came, and then noon. Half the time allotted for the trip had gone, and still there was no sign of deserted mines.
Roger smoked a long pipe after his lunch, chewing impatiently on his pipestem and swearing under his breath from time to time. He was tempted violently to keep on to the north, but remembering Dick's repeated warnings as to the danger of running out of water he finally won his own consent to turning back. He determined, however, to make the return trip on the neighboring range, to the east.
He hoisted his pack and started heavily down into the valley that separated him from the next range. It was a good two miles of tooth and nail climbing and the canyon was filled with afternoon shadows when Roger reached the foot-wall of the east range. The heat was almost intolerable.
