We were now in the heart of the “Rockies.” The valley of the river we were following was about a mile wide, and on either side rose high rocky peaks, covered with perpetual snow, among which big-horns could be seen watching us, the intruders into their domains, and daring us, as it were, to scale the glaciers and meet them on their own ground.

We several times met with moose, one of which was shot nearly every day to supply our camp with meat. We were anticipating getting through the pass without difficulty, when we found ourselves at the bottom of a fall a hundred feet in height, with thickly timbered hills on each side, which, rising abruptly from the water’s edge, seemed to offer no footing even for a snow-shoe, much less a practicable trail for dog-sleighs.

Uncle Donald was not to be defeated, however, and at once ordered a regular track, graded round the face of the bluffs, to be formed. By using snow-shoes as shovels, and poles and brush for bridges, we crossed the intervening gullies and reached the edge of the first fall. Going on a mile further, we found the river confined between perpendicular walls of rock, up which there was no climbing. We had to form another path, carrying it over ledges of rock, banks of ice and snow, making bridges from one huge boulder to another with the dark water boiling at our feet ready to engulf any one who might make a false step.

To our joy, the formidable obstacle being surmounted, the good ice was reached at last, when we pushed on, the dogs trotting gaily along, and we following behind.

But ere long another fall barred our progress. Before attempting to surmount it, we halted for dinner.

As I was looking up I espied a big-horn, or mountain goat, and believing that we could get near enough to shoot it, Hugh and I set off with our guns. The animal is about the size of a common sheep, with conical horns, nearly three feet long, and forming a complete circle, but so thick is the wool which covers its head and body that their full length is not seen.

“Sure, you’ll not be gettin’ up after that baste!” I heard Corney say, he having followed us.

“We’ll try,” I answered, and began ascending the steep rocks. The difficulties were greater than we expected, but still we did not like to be defeated. We had been deceived by the clearness of the atmosphere, and after climbing up and up, the goat appeared as far off as ever. Presently he saw us, and off he bounded, springing along places where it would have been madness to follow.

“I tould ye so!” cried Corney from below, for he had still followed us. “Ye must git above one of those gentlemen if you want to shoot him. Now dinner will be cooked, and we had better be after getting down to eat it.” We accordingly descended to where we had left our snow-shoes.
