'We must have help. I'll go and get our friends. Ye bide here. Maybe Ailie will come back of herself.'

So saying, Mr. Macrae set off on foot across the prairie at a swift pace, far faster than could have been made by the heavily-loaded cart.

Thus left alone, Hector, in spite of himself, began to feel nervous. Snow, the first of the year, began falling softly and silently.

For some time Hector sat waiting, then the happy thought came to him to set the dogs on Ailie's trail. He took from his pocket a ribbon the child had dropped the day before, and showing it to the clever creatures, told them to 'find Ailie.' They seemed to understand at once what was expected of them, and set out on the vanishing, whitening trail, Hector keeping up with them as best he might.

Soon after this, Mr. Macrae and his party arrived, each man bearing a lantern or torch. They were greatly dismayed to find Hector also missing, and doubly hastened their preparations for the search. Under Mr. Macrae's directions, the party, leaving their horses tied to the trees, until they had first made search on foot, spread out in a long line, ten yards or so separating each man from his neighbour, and proceeded to make a thorough search of the prairie.

It was a weird night, and one such as never before had been seen there—the long line of lights bobbing about as the searchers moved through the darkness.

Meanwhile, Hector's search was being diligently made. Dour and Dandy hesitated once or twice as if puzzled, but in a moment trotted on again, and before very long they led Hector to the coulee. The excited boy fell rather than climbed down, and made straight for a sort of pocket in the bank where he could hear the dogs sniffing.

And there lay Ailie! Curled up like a kitten, and so motionless that, for a moment, Hector's heart stood still with fear. Then a quick move forward in the dim light, and his hand was among the clustered curls, and touching the warm, soft neck.

Ailie was alive! hurt, perhaps, but alive, and in the greatness of his joy the boy sent forth a shout that caused Dour and Dandy above to break forth into an 'exposition of barking' that attracted the attention of several of the searchers, making them wonder if the wise dogs might not have discovered something.

Hector picked up Ailie with the utmost tenderness. The child, aroused from her stupor, gave a little cry of fear, then threw her arms about her brother's neck, and burst into tears.
