The pole-star was Roy’s guide. At night he laid his course by it; and by the sun during the day, making constant allowance, of course, for the sun’s rate of travelling through the sky, and taking advantage of all prominent landmarks on the way.

Time sped on; many weary miles were travelled, but no sign of Fort Enterprise was to be seen. Day after day, week after week, month after month they wandered, and still found themselves in the heart of an unknown wilderness. Occasionally they observed signs of Indians, and carefully kept out of sight at such times, as you may easily believe.

At last there came a day when hard frost set in. It was the first touch of another winter. Roy and Nelly did not betray their feelings to each other, but their hearts sank as they thought of what lay before them. The frost was short-lived, however; towards noon the air became delightfully warm, and their spirits revived.

On reaching the summit of an eminence, up which they had toiled for several hours, they beheld a small lake, in which the silvery clouds were clearly reflected. The day was calm; the sun unusually brilliant; the autumnal foliage most gorgeous in colour. It was like a scene in fairy-land!

“Splendid!” exclaimed Roy, sitting down beside his sister on the trunk of a fallen tree.

“Oh! how beautiful,” cried Nelly.

“It’s so like silver,” said Roy.

“Silver Lake,” murmured Nelly.

Roy seemed to think the name appropriate, for he echoed the words, “Yes, Silver Lake.” And there brother and sister sat, for a long time, on the fallen tree, in silent admiration of the scene.
