The wild fawns are able to run well a few days after they are born. They then accompany the mother everywhere. Sometimes she joins a band of others; more often she stays alone with her fawn, and perhaps one of the young of the previous year, until the rut begins. Of all game the prongbuck seems to me the most excitable during the rut. The males run the does much as do the bucks of the mule and whitetail deer. If there are no does present, I have sometimes watched a buck run to and fro by himself. The first time I saw this I was greatly interested, and could form no idea of what the buck was doing. He was by a creek bed in a slight depression or shallow valley, and was grazing uneasily. After a little while he suddenly started and ran just as hard as he could, off in a straight direction, nearly away from me. I thought that somehow or other he had discovered my presence; but he suddenly wheeled and came back to the original place, still running at his utmost speed. Then he halted, moved about with the white hairs on his rump outspread, and again dashed off at full speed, halted, wheeled, and came back. Two or three times he did this, and let me get very close to him before he discovered me. I was too much interested in what he was doing to desire to shoot him.
In September, sometimes not earlier than October, the big bucks begin to gather the does into harems. Each buck is then constantly on the watch to protect his harem from outsiders, and steal another doe if he can get a chance. I have seen a comparatively young buck who had appropriated a doe, hustle her hastily out of the country as soon as he saw another antelope in the neighborhood; while, on the other hand, a big buck, already with a good herd of does, will do his best to appropriate any other that comes in sight. The bucks fight fearlessly but harmlessly among themselves, locking their horns and then pushing as hard as they can.
Although their horns are not very formidable weapons, they are bold little creatures, and if given a chance will stand at bay before either hound or coyote. A doe will fight most gallantly for her fawn, and is an overmatch for a single coyote, but of course she can do but little against a large wolf. The wolves are occasionally very destructive to the herds. The cougar, however, which is a much worse foe than the wolf to deer and mountain sheep, can but rarely molest the prongbuck, owing to the nature of the latter’s haunts. Eagles, on occasion, take the fawns, as they do those of deer.
I have always been fond of the chase of the prongbuck. While I lived on my ranch on the Little Missouri it was, next to the mule-deer, the game which I most often followed, and on the long wagon strips which I occasionally took from my ranch to the Black Hills, to the Big Horn Mountains, or into eastern Montana, prongbuck venison was our usual fresh meat, save when we could kill prairie-chickens and ducks with our rifles, which was not always feasible. In my mind the prongbuck is always associated with the open prairies during the spring, summer, or early fall. It has happened that I have generally pursued the bighorn in bitter weather; and when we laid in our stock of winter meat, mule-deer was our usual game. Though I have shot prongbuck in winter, I never liked to do so, as I felt the animals were then having a sufficiently hard struggle for existence anyhow. But in the spring the meat of the prongbuck was better than that of any other game, and, moreover, there was not the least danger of mistaking the sexes, and killing a doe accidentally, and accordingly I rarely killed anything but pronghorns at that season. In those days we never got any fresh meat, whether on the ranch or while on the round-up or on a wagon trip, unless we shot it, and salt pork became a most monotonous diet after a time.
Occasionally I killed the prongbuck in a day’s hunt from my ranch. If I started with the intention of prongbuck hunting, I always went on horseback; but twice I killed them on foot when I happened to run across them by accident while looking for mule-deer. I shall always remember one of these occasions. I was alone in the Elkhorn ranch-house at the time, my foreman and the only cow-puncher who was not on the round-up having driven to Medora, some forty miles away, in order to bring down the foreman’s wife and sister, who were going to spend the summer with him. It was the fourth day of his absence. I expected him in the evening and wanted to have fresh meat, and so after dinner I shouldered my rifle and strolled off through the hills. It was too early in the day to expect to see anything, and my intention was simply to walk out until I was five or six miles from the ranch, and then work carefully home through a likely country toward sunset, as by this arrangement I would be in a good game region at the very time that the animals were likely to stir abroad. It was a glaring, late-spring day, and in the hot sun of mid-afternoon I had no idea that anything would be moving, and was not keeping a very sharp lookout. After an hour or two’s steady tramping I came into a long, narrow valley, bare of trees and brushwood, and strolled along it, following a cattle trail that led up the middle. The hills rose steeply into a ridge crest on each side, sheer clay shoulders breaking the mat of buffalo-grass which elsewhere covered the sides of the valley as well as the bottom. It was very hot and still, and I was paying but little attention to my surroundings, when my eye caught a sudden movement on the ridge crest to my right, and, dropping on one knee as I wheeled around, I saw the head and neck of a prongbuck rising above the crest. The animal was not above a hundred yards off, and stood motionless as it stared at me. At the crack of the rifle the head disappeared; but as I sprang clear of the smoke I saw a cloud of dust rise on the other side of the ridge crest, and felt convinced that the quarry had fallen. I was right. On climbing the ridge crest I found that on the other side it sank abruptly in a low cliff of clay, and at the foot of this, thirty feet under me, the prongbuck lay with its neck broken. After dressing it I shouldered the body entire, thinking that I should like to impress the new-comers by the sight of so tangible a proof of my hunting prowess as whole prongbuck hanging up in the cottonwoods by the house. As it was a well-grown buck the walk home under the hot sun was one of genuine toil.
The spot where I ran across this prongbuck was miles away from the nearest plains, and it was very unusual to see one in such rough country. In fact, the occurrence was wholly exceptional; just as I once saw three bighorn rams, which usually keep to the roughest country, deliberately crossing the river bottom below my ranch, and going for half a mile through the thick cottonwood timber. Occasionally, however, parties of prongbuck came down the creek bottoms to the river. Once I struck a couple of young bucks in the bottom of a creek which led to the Chimney Butte ranch-house, and stalked them without difficulty; for as prongbuck make no effort to hide, if there is good cover even their sharp eyes do not avail them. On another occasion several does and fawns, which we did not molest, spent some time on what we called “the corral bottom,” which was two or three miles above the ranch-house. In the middle of this bottom we had built a corral for better convenience in branding the calves when the round-up came near our ranch—as the bottom on which the ranch-house stood was so thickly wooded as to make it difficult to work cattle thereon. The does and fawns hung around the corral bottom for some little time, and showed themselves very curious and by no means shy.
When I went from the ranch for a day’s prongbuck hunting of set purpose, I always rode a stout horse and started by dawn. The prongbucks are almost the only game that can be hunted as well during the heat of the day as at any other time. They occasionally lie down for two or three hours about noon in some hollow where they cannot be seen, but usually there is no place where they are sure they can escape observation even when resting; and when this is the case they choose a somewhat conspicuous station and trust to their own powers of observation, exactly as they do when feeding. There is therefore no necessity, as with deer, of trying to strike them at dawn or dusk. The reason why I left the ranch before sunrise and often came back long after dark was because I had to ride at least a dozen miles to get out to the ground and a dozen to get back, and if after industrious walking I failed at first to find my game, I would often take the horse again and ride for an hour or two to get into new country. Prongbuck water once a day, often travelling great distances to or from some little pool or spring. Of course, if possible, I liked to leave the horse by such a pool or spring. On the great plains to which I used to make these excursions there was plenty of water in early spring, and it would often run, here and there, in the upper courses of some of the creeks—which, however, usually contained running water only when there had been a cloudburst or freshet. As the season wore on the country became drier and drier. Water would remain only in an occasional deep hole, and few springs were left in which there was so much as a trickle. In a strange country I could not tell where these water-holes were, but in the neighborhood of the ranch I of course knew where I was likely to find them. Often, however, I was disappointed; and more than once after travelling many miles to where I hoped to find water, there would be nothing but sun-cracked mud, and the horse and I would have eighteen hours of thirst in consequence. A ranch horse, however, is accustomed to such incidents, and of course when a man spends half the time riding, it is merely a matter of slight inconvenience to go so long without a drink.
Nevertheless, if I did reach a spring, it turned the expedition into pleasure instead of toil. Even in the hot weather the ride toward the plains over the hills was very lovely. It was beautiful to see the red dawn quicken from the first glimmering gray in the east, and then to watch the crimson bars glint on the tops of the fantastically shaped barren hills when the sun flamed, burning and splendid, above the horizon. In the early morning the level beams threw into sharp relief the strangely carved and channelled cliff walls of the buttes. There was rarely a cloud to dim the serene blue of the sky. By the time the heat had grown heavy I had usually reached the spring or pool, where I unsaddled the horse, watered him, and picketed him out to graze. Then, under the hot sun, I would stride off for the hunting proper. On such occasions I never went to where the prairie was absolutely flat. There were always gently rolling stretches broken by shallow watercourses, slight divides, and even low mounds, sometimes topped with strangely shaped masses of red scoria or with petrified trees. My object, of course, was, either with my unaided eyes or with the help of my glasses, to catch sight of the prongbucks before they saw me. I speedily found, by the way, that if they were too plentiful this was almost impossible. The more abundant deer are in a given locality the more apt one is to run across them, and of course if the country is sufficiently broken, the same is true of prongbucks; but where it is very flat and there are many different bands in sight at the same time, it is practically impossible to keep out of sight of all of them, and as they are also all in sight of one another, if one flees the others are certain to take the alarm. Under such circumstances I have usually found that the only pronghorns I got were obtained by accident, so to speak; that is, by some of them unexpectedly running my way, or by my happening to come across them in some nook where I could not see them, or they me.
Prongbucks are very fast runners indeed, even faster than deer. They vary greatly in speed, however, precisely as is the case with deer; in fact, I think that the average hunter makes altogether too little account of this individual variation among different animals of the same kind. Under the same conditions different deer and antelope vary in speed and wariness, exactly as bears and cougars vary in cunning and ferocity. When in perfect condition a full-grown buck antelope, from its strength and size, is faster and more enduring than an old doe; but a fat buck, before the rut has begun, will often be pulled down by a couple of good greyhounds much more speedily than a flying yearling or two-year-old doe. Under favorable circumstances, when the antelope was jumped near by, I have seen one overhauled and seized by a first-class greyhound; and, on the other hand, I have more than once seen a pronghorn run away from a whole pack of just as good dogs. With a fair start, and on good ground, a thoroughbred horse, even though handicapped by the weight of a rider, will run down an antelope; but this is a feat which should rarely be attempted, because such a race, even when carried to a successful issue, is productive of the utmost distress to the steed.
Ordinary horses will sometimes run down an antelope which is slower than the average. I once had on my ranch an under-sized old Indian pony named White Eye, which, when it was fairly roused, showed a remarkable turn of speed, and had great endurance. One morning on the round-up, when for some reason we did not work the cattle, I actually ran down an antelope in fair chase on this old pony. It was a nursing doe, and I came over the crest of the hill, between forty and fifty yards away from it. As it wheeled to start back, the old cayuse pricked up his ears with great interest, and the moment I gave him a sign was after it like a shot. Whether, being a cow-pony, he started to run it just as if it were a calf or a yearling trying to break out of the herd, or whether he was overcome by dim reminiscences of buffalo-hunting in his Indian youth, I know not. At any rate, after the doe he went, and in a minute or two I found I was drawing up to her. I had a revolver, but of course did not wish to kill her, and so got my rope ready to try to take her alive. She ran frantically, but the old pony, bending level to the ground, kept up his racing lope and closed right in beside her. As I came up she fairly bleated. An expert with the rope would have captured her with the utmost ease; but I missed, sending the coil across her shoulders. She again gave an agonized bleat, or bark, and wheeled around like a shot. The cow-pony stopped almost, but not quite, as fast, and she got a slight start, and it was some little time before I overhauled her again. When I did I repeated the performance, and this time when she wheeled she succeeded in getting on some ground where I could not follow, and I was thrown out.
