This remark convinced me more than ever that the stranger had some reason for not wishing to have any intercourse with the garrison. I wished him “good-bye,” and he plunging into the forest, I soon rejoined my companions.

We returned with a large supply of venison. My father, to whom I privately communicated the information I had received from the stranger, announced his intention of setting out next morning.

The harness during our stay had been put in good order. My horse, thanks to the remedies applied by the surgeon, had completely recovered, and we purchased another for Dio.

Everything being ready at the time appointed, we recommenced our journey, saluted by the cheers of the garrison. Our course was now towards the north-west, which would lead us across the Laramie plains, over a range of the Rocky Mountains, beyond which my father expected from the report of hunters and trappers to find a fertile region, in which he would be content to establish himself. We had added, I should have said, two light carts, in which we intended to transport the cargoes of the waggons, should we find it impossible to drag them when laden over the heights. As we travelled on I fully expected to fall in with the stranger, but day after day went by and he did not make his appearance. Following the advice given, we halted only to rest our animals. On such occasions we employed the time in hunting, and seldom returned without a supply of either buffalo meat or venison. The Indians we met with appeared disposed to be friendly, or at all events, seeing our large well-armed party, and the vigilant watch we kept, they did not venture to interfere with us. We were approaching the range it was our purpose to cross. We had heard that many of the heights were of great elevation, but that there were passages or cañons between them, through which we might make our way, provided no enemy should appear to impede our progress. We had during the last day caught sight of what appeared a bank of white clouds, their outer edges lighted up by the rays of the sun. During, however, the next couple of days’ journey a light mist hung over the country, which prevented us from seeing objects at a distance. Having no longer the fear of Indians, the Dominie, Dan, and I frequently went ahead, sometimes on horseback and sometimes on foot, for the purpose of killing game or exploring the way. Thus one day, the ground being rugged and the waggons making but slow progress, we had proceeded some distance further than usual when we caught sight, on the top of a rock, of an animal with long horns, which Dan declared was a sheep, and which I thought was a deer.

“Dan is more nearly right, for it is the sheep of these mountains, but in its habits it is very like the chamois of Switzerland,” observed the Dominie; “we have very little chance of getting that fellow, but we may kill others if we are on the watch for them. It is the big-horn, or ‘grosse corne,’ as the French call it, of the Rocky Mountains. It has already seen us, and away it goes to some place where it knows we cannot reach it.”

I may as well say that this wild sheep is of stout build, and has feet stronger and larger than those of the deer. Its light dusky brown colour is similar to the tint of the rocks among which it lives. About its ears and neck and legs it carries a small quantity of wool, the rest of its coat consisting of coarse hair, white on the rump, while the tail is tipped with black. Both the male and female have horns, those of the former being remarkable for their enormous size, while those of the latter somewhat resemble the horns of the ordinary goat. The horns of some of the sheep we afterwards killed measured upwards of two feet six inches in length. The head is provided with cartilaginous processes of great strength, and they with the frontal bone form one strong mass of so solid a nature that the animal can, when making his escape, fling himself on his head from considerable heights without injury.

We watched the big-horn as it bounded away, until it speedily disappeared.

Almost immediately afterwards the mist lifted, and we saw before us a range of mountains with a snow-capped peak, apparently of great elevation, rising beyond them, while at their foot slept a lake of clear water, shining like a polished mirror in the rays of the sun.

“What! shall we have to cross all those mountains?” exclaimed Dan, “we shall be brought to a stand-still, I fear.”

“We shall have to get through them somehow or other, but I hope that a passage may be found up a cañon, between the rocky heights, so that we shall not be compelled to climb over their tops,” answered Mr Tidey. “The sooner, however, we get back to camp and look out for the required pass the better. It may take us some days, and as the season is advancing there is no time to be lost.”
