“Where is the caribou migration in here?” asked John.

“It won’t pass here at all,” replied their leader. “They tell me that the caribou are north of the Porcupine, toward the Arctic, and that they work south along toward the latter part of August. There are a few sheep in here, but mountain-sheep is a hard meat to kill. There is mighty little hope for us to get anything unless we can catch some fish as we go along—and unless we continue to eat rabbits, and maybe some ptarmigan. I shouldn’t wonder if the ptarmigan would grow much scantier when we get down out of the mountains farther.

“Jesse,” he continued, “there’ll be no harm in your taking your gun and going over to see if you can get us some young geese or some young ducks before we start out, over at the edge of Loon Lake. We’ve got to have all the food-supplies we can possibly get hold of, because we don’t know what is ahead. Hurry up, now, for pretty soon we must call ourselves rested and be on our way. Our canoe is waiting for us, already launched, and it won’t take long to get the loads aboard.”

Jesse complied with his uncle’s instructions, and, taking his light shot-gun, disappeared in the fringe of willows which lay between the camp and the marshy borders of the lake out of which they had made their last portage on the Rocky Mountain summit. It was not long before they began to hear the reports of his gun, and so proficient had he by this time become in its use that when he returned in the course of three-quarters of an hour he had a young goose and a half-dozen mallard ducks to add to the larder.

“Fine!” said Uncle Dick. “Throw them in the boat, son, and we’ll be getting ready.

“Rob, go on with your diary; and, John, be sure that you keep up your maps. There isn’t a single report of any kind in print or in manuscript, so far as I know, which tells the truth about this summit of the Rockies. We are just as much explorers as if we were the first to cross. The Klondikers left no records.

“And now take one last look around you, for I question if you will ever be in a more remote corner of the world in all your lives. This is the most northerly pass of the Rockies. Yonder above us, at the end of what they call the Black Mountain range, lie the last foot-hills between here and the Arctic. Off in that direction the Little Bell finds its head—no man knows where, so far as I can tell. Westward in general lies our course now, and we’ve got to make five hundred miles between McPherson and the mouth of the Porcupine River, and make it in jig time too, if we want to catch an up-bound boat on the Yukon this fall.”

“Well,” said Rob, “I suppose if we had to we could play Robinson Crusoe here at least as well as those poor Klondikers did who came to grief here twenty years ago. But as for me, I want to get home on time—not only because we have to go to school and because our parents are waiting for us, but because we set out to make our round trip within certain dates, and we ought to do so if that is a possible thing.”

“That’s the talk!” said Uncle Dick. “Come ahead then, boys. Now we are alone—let us see how we can travel.”
