The Airedale cocked up one ear on hearing his young master's voice, then, putting his head knowingly on one side, as if he understood every word that had been said, he trotted to the front and splashed through the pools of mud and water, his stump of a tail wagging with evident satisfaction.
Ross was used to all kinds of weather, but a downpour such as this he had never seen before. The rain fell steadily and relentlessly, with never a pause between. The night was too dark to see clearly, as the sheets of water were swept before the wind, but their force was terrific. Several times the boy had to turn his back to the driving storm and gasp, in order to get his breath.
"Where are you going, old boy?" again queried Ross.
The terrier paused, shook himself so that the drops flew in all directions, looked up in his master's face, gave a short sharp bark and trotted on.
Ross leaned down, patted the dog, and followed. By some instinct of his own, the terrier was keeping to a submerged road, though how he managed to remain on it was beyond the lad's comprehension, for the night was as dark as a wolf's throat and the path was under water half the time.
Suddenly the dog stopped and looked back as though for guidance. Before them was a swirl of water. In the darkness it was impossible to say how deep the wash-out might be, or how wide. Ross hesitated. His father had warned him against foolhardiness, and here he was facing the crossing of a swift current of unknown depth on a pitch-black night. Should he venture?
Rex barked, a short excited "yap" of urgency.
"I'll go as far as I can wade, anyhow," said Ross in response; "maybe it isn't so deep after all. I'm not particularly anxious to have to swim."
The terrier watched his master, and as soon as the boy started to cross the wash-out in the road-bed, the dog plunged in. The current swept him down rapidly, but Rex was a powerful swimmer and the lad had little fear for him. It took all his own strength to keep him from being swept off his feet, but the break in the road was not more than six yards across, and the boy was soon safe on the other side. He whistled shrilly and a moment or two later, Rex came bounding up and jumped on his master with clumsy delight. Then, with another cock of his head, as though to make sure of himself, he took up his position in front of the lad and trotted ahead.
How it rained! The water had gone down Ross's neck and inside his shoes, so that they sloshed and gurgled with each step. Little rills of water trickled coldly down his back and legs. The wind was dropping, so that the rain drove less in slanting sheets, but it seemed to pelt down all the more heavily for that. Even in the darkness, Ross could see the plops, where the drops fell, standing up from the surface of the flooded water like so many spiny warts. It was lonely, even with Rex for company, so dark and so wet was the night, and Ross was glad when the glow of a fire in the distance told him that he was approaching an encampment, probably, he thought, that of another group of settlers who had been driven from their flooded houses and were shivering, homeless, in the night.
