“Boys,” he said, “we’ll get on again.”

They went on, and the memory of that afternoon long remained with them. They were grimed with black dust and ashes, and the ranks of charred trunks cast only thin strips of shade, while a scorching sun poured down an almost intolerable heat into the deep valley. The ground was ankle-deep in dust and charcoal, and, as they floundered through it, feathery ash rose in clouds. Their clothing grew crusted with it, and it worked through and irritated their heated skin; while every now and then one of them was compelled to stop and splutter. Their throats, as Grenfell remarked, certainly felt very much like ash-heaps. None of them had drunk anything since supper the night before, and then only a very little water that tasted alkaline.

Still, except for the loose deposit that made walking difficult, the ground was comparatively clear, and they pushed on, making a detour only now and then around a fallen tree, or waiting for Grenfell, who lagged behind and limped, until the slanting rays beat pitilessly into their faces and their aching eyes were dazzled by the burning glow. Then Grenfell sat down rather frequently.

“We’re going northwest,” said Weston once, while they waited for him. “You said that was how you headed the day before you struck the lake.”

“Yes,” said Grenfell, with an air of trying to recall something. “It was summer, and at sunset the light was in our eyes. There was a very rugged strip on the range—not unlike that one yonder. Still, I can’t be sure.”

Nothing more was said. It was quite clear that Grenfell’s memory was not to be trusted, and they were in no mood for talking. They went on a little more slowly, but Grenfell lagged again, and it was a vast relief to all of them when the glare that hurt their eyes died out suddenly as the red sun dipped behind a wall of rock. Half an hour later the heat of the brûlée seemed to dissipate, and a wondrous invigorating coolness crept in with the dusk, when they made their camp and picketed the jaded horse. It did not seem worth while to light a fire, as they had no water to use for tea; and, after eating a little grindstone bread and salt pork cooked the previous day, they lay down rolled in their blankets.

CHAPTER XXII

GRENFELL GOES ON

Weston, tired as he was, did not sleep well that night. Although they had a pack-horse he had carried two blankets and a bag of flour, and when a man has marched from sunrise until dusk under a heavy burden, his shoulders, as a rule, ache distressfully. In addition to this discomfort, Grenfell’s manner throughout that day’s march had roused an unsettling sense of expectation in his comrades. The man had limped wearily and continually lagged behind, but he had, in spite of it, resolutely insisted on their pushing on as fast as possible. He had also looked about him with a certain suggestive curiosity every now and then, and though he had once or twice admitted that he could not positively identify anything he saw, his air of restrained eagerness had made its impression on Weston.

A half-moon had sailed up into the eastern sky when the latter wakened and raised himself drowsily on one elbow. All round him the great burned pines towered in black and shadowy columns against the silvery light, and a stillness that was almost oppressive brooded over the valley. No sound of running water came out of it, and there was not a breath of wind. It was cool, however, and Weston drew his dusty blanket higher about his shoulders as he glanced round the camp. Devine lay close by sleeping like a log; but Grenfell was huddled at the foot of a tree, and it became evident to his comrade that he, at least, was wide awake.
