A little beyond this they went into camp, but just before passing into the little park where they were to camp, Hugh stopped his horse and said to Jack: "There's a queer looking antelope; ride on ahead, son, and see if you can't kill it."
As he reached the edge of the little park, Jack stopped in the fringe of timber and looking through, saw a half a dozen antelope scattered about feeding. The head of one of the bucks that was nearest to him had an odd appearance, and even looked as if it had two sets of horns. It was a good-sized animal, and Jack slipped from his horse, and creeping out to the edge of the timber, where he had a clear, open sight, raised his rifle to shoot. The motion caught the buck's eye and he turned about and stood facing Jack, looking at him. Jack drew a careful sight and fired, and the antelope reared up straight on his hind legs and then fell over backward. Jack reloaded, and going back, mounted and rode out to the buck, which he found dead, the ball having passed lengthwise through the body. The curious appearance of the animal's head was explained as soon as he reached it, for this buck actually had four horns; the two usual ones, and, growing from the skin behind each one, at a distance of a couple of inches from the horns, were two other stout, black horns about three inches long and an inch thick. These were not attached to the skull, but were mere outgrowths from the skin and moved about with the skin when it was moved.
Jack had seen nothing like this before, and he was very much surprised at it. While he was preparing the antelope to take into camp, Hugh and the animals came along and passed him, stopping at the edge of the stream not more than a hundred yards from where he was skinning the antelope. Jack stripped the hide from the beast, and, cutting off the skin of the neck low down at the breast and shoulders, placed the carcass across his saddle, and carrying the head in his hand, walked into camp.
The horses were already unpacked and feeding about, dragging their ropes, and Hugh had started his fire and brought the water. It took but a short time to put up the tent, and then to picket the horses.
"I want to tie up the horses for the present, son," said Hugh, "because here in the timber it's pretty easy for us to lose them. They may wander off only a short distance, but if they keep quiet in the brush or timber it may take us a long time to find them. It's different down on the open prairie, where you can see a long way." Each horse, therefore, was tied up, either made fast to a picket pin driven firmly in the ground, or to some stout tuft of sage brush.
After supper Jack brought out his antelope head and asked Hugh about it.
"Yes," said Hugh, "I've seen antelope like this before, but I don't know that I can explain to you why this fellow has these extra horns. I reckon they're something like the horns you'll often see on a doe antelope. Some does—maybe most of them—have no horns at all, but others will have a little knob of horn, perhaps not more than half an inch long, just sort o' capping the little bunch on each side of the head that corresponds with the big bony cores of the buck antelope's head; and others may have right long horns, maybe four or six inches long, with a little sign of a prong on the horn, but I've never seen a doe's horns that were firm on the skull and that had a bony core inside them as a buck's horns always have. The doe's horns always seem to just grow on the skin like these extra horns on this head. I have often seen buck antelope that had little, hard, black bunches looking just like the stuff the horns are made of, growing on the skin of the head somewhere near the horns, but I don't know what it means, no more than I know what it means when a rabbit has a horn or a pair of horns."
"What do you mean, Hugh?" said Jack. "Do rabbits ever have horns? I never heard of anything like that."
"Oh, yes," said Hugh; "sometimes they have horns, but I don't know why, nor do I know what the horns mean. I've had rabbits with horns, both jackrabbits and cottontails, shown to me a good many times."
"What!" said Jack; "real horns, you mean, growing out of the head like an antelope's horns or a cow's horns?"
