How long he thus literally fought against the elements it was impossible for him so much as to conjecture.
He knew his strength was spending rapidly; and when it seemed as if he could not take another step, he stumbled, and fell against a mound of sand.
It had been built by the "dancing giants" when some obstruction had been found in the path of the storm; and as Dick fell prostrate at the foot of this slight elevation, there instantly came a sense of deepest relief.
The sand was no longer thrown against him by the blast; the wind had ceased to buffet him; he was in comparative quiet, and for an instant he failed to understand the reason.
Then he realized that this mound, which had thrown him from his feet, was affording a shelter against the tempest, which was now coming from one direction instead of in a circle as heretofore; and a fervent prayer of thanksgiving went up from his heart, for he believed his life had been saved that he might aid his father.
After recovering in a measure from the exhaustion consequent upon his battle with the elements, he proceeded with infinite care to brush the particles of sand from his face; and this done, his relief was yet greater.
Overhead the air was full of darkness; the wind still screamed as it whirled aloft the spiral columns of dust; the wave-like drift of the sand surged on either side; but for the moment he was safe.
He had been told that such tempests were of but short duration, and yet it seemed to him as if already half a day had been spent in this fight for life.
Then he said to himself that he could remain where he was in safety until the wind had subsided; but even as the words were formed in his mind he was conscious of a weight upon his limbs as if something was bearing him down, and for the first time he realized that he was being rapidly buried alive.
To remain where he was ten minutes longer must be fatal; and perhaps even that length of time would not be allowed him, for if the wind so shifted as to cut off the top of the mound, then he would be overwhelmed as if in a landslide.
