lee of a rock, they waited, hoping the storm was only a squall, such as frequently whipped across the open places. The moan increased to a roar, and the dull red slowly dimmed, to disappear in the yellow pall, and the air grew thick and dark. Warren slipped the packs from the burros. Cameron feared the sandstorms had arrived some weeks ahead of their usual season.
The men covered their heads and patiently waited. The long hours dragged, and the storm increased in fury. Cameron and Warren wet scarfs with water from their canteens, and bound them round their faces, and then covered their heads. The steady, hollow bellow of flying sand went on. It flew so thickly that enough sifted down under the shelving rock to weight the blankets and almost bury the men. They were frequently compelled to shake off the sand to keep from being borne to the ground. And it was necessary to keep digging out the packs. The floor of their shelter gradually rose higher and higher. They tried to eat, and seemed to be grinding only sand between their teeth. They lost the count of time. They dared not sleep, for that would have meant being buried alive. They could only crouch close to the leaning rock, shake off the sand, blindly dig out their packs, and every moment gasp and cough and choke to fight suffocation.
The storm finally blew itself out. It left the prospectors heavy and stupid for want of sleep. Their burros had wandered away, or had been buried in the sand. Far as eye could reach the desert had marvelously changed; it was now a rippling sea of sand dunes. Away to the north rose the peak that was their only guiding mark. They headed toward it, carrying a shovel and part of their packs.
At noon the peak vanished in the shimmering glare of the desert. The prospectors pushed on, guided by the sun. In every wash they tried for water. With the forked peach branch in his hands Warren always succeeded in locating water. They dug, but it lay too deep. At length, spent and sore, they fell and slept through that night and part of the next day. Then they succeeded in getting water, and quenched their thirst, and filled the canteens, and cooked a meal.
The burning day found them in an interminably wide plain, where there was no shelter from the fierce sun. The men were exceedingly careful with their water, though there was absolute necessity of drinking a little every hour. Late in the afternoon they came to a cañon that they believed was the lower end of the one in which they had last found water. For hours they traveled toward its head, and, long after night had set, found what they sought. Yielding to exhaustion, they slept, and next day were loath to leave the waterhole. Cool night spurred them on with canteens full and renewed strength.
Morning told Cameron that they had turned back miles into the desert, and it was desert new to him. The red sun, the increasing heat, and especially the variety and large size of the cactus plants warned Cameron that he had descended to a lower level. Mountain peaks loomed on all sides, some near, others distant; and one, a blue spur, splitting the glaring sky far to the north, Cameron thought he recognized as a landmark. The ascent toward it was heartbreaking, not in steepness, but in its league-and-league-long monotonous rise. Cameron knew there was only one hopeâto make the water hold out and never stop to rest. Warren began to weaken. Often he had to halt. The burning white day passed, and likewise the night, with its white stars shining so pitilessly cold and bright.
Cameron measured the water in his canteen by its weight. Evaporation by heat consumed as much as he drank. During one of the rests, when he had wetted his parched mouth and throat, he found opportunity to pour a little water from his canteen into Warrenâs.
At first Cameron had curbed his restless activity to accommodate the pace of his elder comrade. But now he felt that he was losing something of his instinctive and passionate
