A misfortune soon after this befell Dick Varley, which well-nigh caused him to give way to despair. For some time past he had been approaching the eastern slopes of the Rocky Mountains—those ragged, jagged, mighty hills, which run through the whole continent from north to south in a continuous chain, and form, as it were, the backbone of America. One morning, as he threw the buffalo robe off his shoulders and sat up, he was horrified to find the whole earth covered with a mantle of snow. We say he was horrified, for this rendered it absolutely impossible any further to trace his companions either by scent or sight.

For some time he sat musing bitterly on his sad fate, while his dog came and laid his head sympathisingly on his arm.

“Ah! pup,” he said, “I know ye’d help me if ye could! But it’s all up now; there’s no chance of findin’ them—none.”

To this Crusoe replied by a low whine. He knew full well that something distressed his master, but he hadn’t yet ascertained what it was. As something had to be done, Dick put the buffalo robe on his steed, and, mounting, said, as he was in the habit of doing each morning, “Lead on, pup.”

Crusoe put his nose to the ground and ran forward a few paces, then he returned and ran about snuffing and scraping up the snow. At last he looked up, and uttered a long melancholy howl.

“Ah! I knowed it,” said Dick, pushing forward. “Come on, pup, you’ll have to follow now. Any way we must go on.”

The snow that had fallen was not deep enough to offer the slightest obstruction to their advance. It was, indeed, only one of those occasional showers common to that part of the country in the late autumn, which season had now crept upon Dick almost before he was aware of it, and he fully expected that it would melt away in a few days. In this hope he kept steadily advancing, until he found himself in the midst of those rocky fastnesses which divide the waters that flow into the Atlantic from those that flow into the Pacific Ocean. Still the slight crust of snow lay on the ground, and he had no means of knowing whether he was going in the right direction or not.

Game was abundant, and there was no lack of wood now, so that his night bivouac was not so cold or dreary as might have been expected.

Travelling, however, had become difficult, and even dangerous, owing to the rugged nature of the ground over which he proceeded. The scenery had completely changed in its character. Dick no longer coursed over the free, open plains, but he passed through beautiful valleys filled with luxuriant trees, and hemmed in by stupendous mountains, whose rugged sides rose upward until the snow-clad peaks pierced the clouds.

There was something awful in these dark solitudes, quite overwhelming to a youth of Dick’s temperament; his heart began to sink lower and lower every day, and the utter impossibility of making up his mind what to do became at length agonising. To have turned and gone back the hundreds of miles over which he had travelled would have caused him some anxiety under any circumstances, but to do so while Joe and Henri were either wandering about there or in the power of the savages, was, he felt, out of the question. Yet, in which way should he go? Whatever course he took might lead him further and further away from them.
