"Rogers never told us anything about this. It's getting worse every minute. I----" A shower of pebbles and a great cloud of metallic dust swept past, leaving them choking and gasping for breath. The Very Young Man got upon his hands and knees. "I'm going over there," he panted. "It's better." CHAPTER XIV STRANGE EXPERIENCES Led by the Very Young Man, the three crawled a few yards to where a cluster of bowlders promised better shelter. Huddled behind this mass of rock, they found themselves protected in a measure from the violence of the storm. Lying there, they could see yellowish-gray clouds of sand go sweeping by, with occasionally a hail of tiny pebbles, blowing almost horizontal. Overhead, the sky was unchanged. Not a vestige of cloud was visible, only the gray-blue of an immense distance, with the huge gleaming light, like an enormous sun, hung in its center. The Very Young Man put his hand on the Doctor's arm. "It's going down," he said. Hardly were the words out of his mouth before, with even less warning than it began, the gale abruptly ceased. There remained only the pleasantly gentle breeze of a summer afternoon blowing against their faces. And this came from almost an opposite direction to the storm. The three men looked at one another in amazement. "Well, I'll be----" ejaculated the Very Young Man. "What next?" They waited for some time, afraid to venture out from the rocks among which they had taken refuge. Then, deciding that the storm, however unexplainable, was over for the time at least, they climbed to their feet and resumed their journey with bruised knees, but otherwise none the worse for the danger through which they had passed. After walking a short distance, they came up a little incline, and before them, hardly more than a quarter of a mile away, they could see a range of hills. "The scratch must be behind those hills," said the Very Young Man, pointing. "It's a long distance," said the Big Business Man thoughtfully. "We're still growing smaller--look." Their minds had been so occupied that for some time they had forgotten the effect of the drug upon their stature. As they looked about them now they could see the rocks around them still increasing steadily in size, and could feel the ground shifting under their feet when they stood still. "You're right; we're getting smaller," observed the Very Young Man. "How long before we'll stop, do you suppose?" The Doctor drew the Chemist's memoranda from the pouch of his belt. "It says about five or six hours for the first four pellets," he read. The Very Young Man looked at his watch. "Quarter to nine. We've been less than an hour yet. Come on, let's keep going," and he started walking rapidly forward. They walked for a time in silence. The line of hills before them grew visibly in size, and they seemed slowly to be nearing it.
