There came a morning when the sun shone angry and red through a dull, smoky haze.
"We're in for sandstorms," said Cameron.
They had scarcely covered a mile when a desert-wide, moaning, yellow wall of flying sand swooped down upon them. Seeking shelter in the 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.
The 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 let 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 canyon 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 hear, 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 hope--to 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 Warren's.
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 zeal to get out of the desert. The thought of water came to occupy his mind. He began to imagine that his last little store of water did not appreciably diminish. He knew he was not quite right in his mind regarding water; nevertheless, he felt this to be more of fact than fancy, and he began to ponder.
When next they rested he pretended to be in a kind of stupor; but he covertly watched Warren. The man appeared far gone, yet he had cunning. He cautiously took up Cameron's canteen and poured water into it from his own.
This troubled Cameron. The old irritation at not being able to thwart Warren returned to him. Cameron reflected, and concluded that he had been unwise not to expect this very thing. Then, as his comrade dropped into weary rest, he lifted both canteens. If there were any water in Warren's, it was only very little. Both men had been enduring the terrible desert thirst, concealing it, each giving his water to the other, and the sacrifice had been useless.
Instead of ministering to the parched throats of one or both, the water had evaporated. When Cameron made sure of this, he took one more drink, the last, and poured the little water left into Warren's canteen. He threw his own away.
Soon afterward Warren discovered the loss.
"Where's your canteen?" he asked.
"The heat was getting my water, so I drank what was left."
"My son!" said Warren.
The day opened for them in a red and green hell of rock and cactus.
Like a flame the sun scorched and peeled their faces. Warren went blind from the glare, and Cameron had to lead him. At last Warren plunged down, exhausted, in the shade of a ledge.
