Breakfast that morning was rather a hurried affair, for there was much to be done. The 138supplies had been brought up from the store the night before so there was no need to wait for the place to open, and Anvik proved to be quite handy in striking camp, needing few instructions. He remembered well all that had been told him the previous day.

They got away early. As before, the guide disdained to ride his pony. He trotted along ahead, leading the little animal until some five miles beyond the village when he leaped to the pony’s back, and with a shrill “Yip, yip!” sent it galloping ahead. This made the boys laugh. They did not laugh for long, however. A mile beyond this they swerved from the trail that led up parallel with the border between the United States and the Canadian possessions and struck straight into the wilds.

“Say, where’s the trail?” demanded the perspiring Stacy when the going became so rough that the greater part of the time they were obliged to walk, leaving their ponies to get along as best they might.

“There is no trail. This is the trackless wilderness,” replied Butler. “There is time to go back if you wish to.”

“No, I don’t want to go back.”

Ere that day was ended Chunky almost wished he had gone back while he had the opportunity. Time and time again they were 139 obliged to haul their ponies up the steep sides of rocks by main force. Fortunately, the little animals, used to mountain climbing, were unaffected by dizzy heights or dangerous crossings, and picked their way almost daintily. The boys were perspiring and red of face, but happy. They thoroughly enjoyed this wild traveling. It went beyond anything they had ever experienced.

“I hope you are satisfied,” panted the Professor when at noon they stopped on a little plateau from which gulches fell away on all sides, leaving them, as it were, on a magic island high in the air. “I sincerely hope it is wild enough for you young gentlemen.”

“Not any too much so, Professor,” answered Tad. “I could stand it a lot wilder.”

“At the present rate you will have it that way.”

They built a fire and cooked a light meal, after which all hands lay down for an hour, with the exception of Anvik, who sat bunched in his now familiar brooding position, gazing off into space. As he sat thus, his far-seeing eyes discovered something, but he did not change countenance. He simply sat in dreamy-eyed silence. Perhaps what he saw did not interest him. A column of white smoke had attracted his attention. Promptly on the expiration 140of the hour that the boys had given themselves to sleep, Anvik stepped briskly to them, shaking each one by the shoulder.
