Three days more and our young friends bade farewell to Silver Lake.

Short though their stay had been, it had proved very pleasant, for it was full of energetic labour and active preparation, besides a great deal of amusement, so that quite a home feeling had been aroused in their minds, and their regret at leaving was considerable.

But after the first few miles of their journey had been accomplished, the feeling of sadness with which they set out wore away, and hopeful anticipations of being home again in a few weeks rendered them cheerful, and enabled them to proceed with vigour. The weather at starting was fine, too, so that the night encampments in the snow were comparatively agreeable, and the progress made during the first few days was satisfactory.

After this, however, the good fortune of our adventurers seemed to desert them. First of all one of Nelly’s snow-shoes broke down. This necessitated a halt of half a day, in order to have it repaired. Then one of Roy’s snow-shoes gave way, which caused another halt. After this a heavy snow-storm set in, rendering the walking very difficult, as they sank, snow-shoes and all, nearly to the knees at each step. A storm of wind which arose about the same time, effectually stopped their farther advance, and obliged them to take to the shelter of a dense part of the woods and encamp.

During three days and three nights the hurricane raged, and the snow was blown up in the air and whirled about like the foam of the roaring sea; but our wanderers did not feel its effects much, for they had chosen a very sheltered spot at the foot of a large pine, which grew in a hollow, where a cliff on one side and a bluff of wood on the other rendered the blast powerless. Its fierce howling could be heard, however, if not felt; and as the brother and sister lay at the bottom of their hole in the snow, with their toes to the comfortable fire, they chatted much more cheerily than might have been expected in the midst of such a scene, and gazed upward from time to time with comparative indifference at the dark clouds and snow-drifts that were rushing madly overhead.

On the fourth day the gale subsided almost as quickly as it had arisen, and Roy announced that it was his intention to start. In a few minutes everything was packed up and ready.

“I say, Nell,” said Roy, just as they were about to leave the camp, “don’t the sled look smaller than it used to?”

“So it does, Roy; but I suppose it’s because we have eaten so much during the last three days.”

Roy shook his head, and looked carefully round the hole they were about to quit.

“Don’t know, lass; it seems to me as if somethin’ was a-wantin’. Did ye pack your own bundle very tight?”

“Yes; I think I did it tighter than usual, but I’m not very sure.”

“Hum—that’s it, no doubt—we’ve packed the sled tighter, and eaten it down. Well, let’s off now.”

So saying, Roy threw the lines of the sledge over his shoulder and led the way, followed by his sister, whose only burden was a light blanket, fastened as a bundle to her shoulders, and a small tin can, which hung at her belt.

The country through which they passed that day was almost destitute of wood, being a series of undulating plains, with clumps of willows and stunted trees scattered over it like islets in the sea. The land lay in a succession of ridges, or steppes, which descended from the elevated region they were leaving, and many parts of these ridges terminated abruptly in sheer precipices from forty to sixty feet high.

The sun shone with dazzling brilliancy, insomuch that the travellers’ eyes became slightly affected by snow-blindness. This temporary blindness is very common in these regions, and ranges from the point of slight dazzlement to that of total blindness; fortunately it is curable by the removal of the cause—the bright light of the sun on pure snow. Esquimaux use “goggles” or spectacles made of wood, with a narrow slit in them as a preventive of snow-blindness.

At first neither Roy nor Nelly felt much inconvenience, but towards evening they could not see as distinctly as usual. One consequence of this was, that they approached a precipice without seeing it. The snow on its crest was so like to the plain of snow extending far below, that it might have deceived one whose eyesight was not in any degree impaired.

The first intimation they had of their danger was the giving way of the snow that projected over the edge of the precipice. Roy fell over headlong, dragging the sledge with him. Nelly, who was a few feet behind him, stood on the extreme edge of the precipice, with the points of her snow-shoes projecting over it. Roy uttered a cry as he fell, and his sister stopped short. A shock of terror blanched her cheek and caused her heart to stand still. She could not move or cry for a few seconds, then she uttered a loud shriek and shrank backwards.

There chanced to be a stout bush or tree growing on the face of the cliff, not ten feet below the spot where the snow-wreath had broken off. Roy caught at this convulsively, and held on. Fortunately the line on his shoulder broke, and the............
