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 canon, 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." We accordingly turned back, and on reaching the train found that the mountains were as clearly visible as from where we had first seen them. Near at hand was a rocky height, to the top of which my father and uncle climbed with us, carrying their spy-glasses that they might take a view of the range, and endeavour to discover some opening through which we might hope to make our way. "Others have gone through yonder rocky barrier, and so may we," said my father, sweeping the range from north to south with his telescope. After surveying the mountain for some time, he exclaimed, "I see what looks like a canon where the cliffs appear to rise almost perpendicularly out of the plain. We will direct our course towards it. We shall not reach it to-night, but we will explore it with our carts to-morrow morning, while we leave the waggons in a safe position, so that they may be effectually defended should any Indians venture to attack them, though I have no apprehensions on that score."
