For the present, however, there were none of these human enemies near, and the host rolled on southward, with its bellowings and its tramplings, unmolested. Neither Indians nor white men approached this stage of the migration. The autumn days were sunny, beneath a sky bathed in dream. The autumn nights were crisp with tonic frost, and in the pink freshness of the dawn a wide-flung mist arose from the countless puffing nostrils and the frost-rimed, streaming manes. Pasturage was abundant, the tempers of the great bulls were bold and pugnacious, and nothing seemed less likely than that any disaster could menace so mighty and invincible a host. Yet Brown Bull was uneasy. From time to time he would lift his red-rimmed nostrils, sniff the air in every direction, and scan the summits of the foothills far on the right, as if the unknown peril which he apprehended was likely to come from that direction.
As day by day passed on without event, the diffused anxiety of the host quite died away. But Brown Bull, with his wider sagacity or more sensitive intuition, seemed to grow only the more apprehensive and the more vigilant. His temper did not improve under the strain, and his little troop of followers was herded with a severity which must have taxed, for the moment, their faith in its beneficence.
The host lived, fought, fed, as it went, halting only for sleep and the hours of rest. In this inexorable southward drift the right flank passed one morning over a steep little knoll, the crest of which chanced to be occupied by Brown Bull and his herd just at the moment when the moving ranks came to a halt for the forenoon siesta. It was such a post of vantage as Brown Bull loved. He stood there sniffing with wide, wet nostrils, and searching the horizon for danger. The search was vain, as ever; but just behind him, and closer in toward the main body of the host, he saw something that made his stretched nerves thrill with anger. An old bull had just been driven out from a neighboring herd, deposed from his lordship and hideously gored by a younger and stronger rival. Staggering from his wounds, and overwhelmed with a sudden terror of isolation, he tried to edge his way into the herd next behind him. He was ejected mercilessly. From herd to herd he staggered, met always by a circle of lowered horns and angry eyes, and so went stumbling back to that lonely doom which, without concern, he had seen meted out to so many of his fellows, but had never thought of as possible to himself. This pitiful sight, of course, was nothing to Brown Bull. It hardly even caught his eye, still less his interest. Had he been capable of formulating his indifferent thoughts upon the matter, they would have taken some such form as: "Serve him right for being licked!" But when at last the wounded outcast was set upon by four big timber wolves and pulled, bellowing, to his knees, that was another affair. Brown Bull could not tolerate the sight of the gray wolves triumphing. With a roar of rage he charged down the knoll. His herd, astonished but obedient, lowered their massive heads and charged at his heels. The wolves snarled venomously, forsook their prize, and vanished. Brown Bull led the charge straight on and over the body of the dying outcast, trampling it into dreadful shapelessness. Then, halting abruptly, he looked about him in surprise. The wolves were gone. His rage passed from him. He led his followers tranquilly back to their place on the knoll, to the accompaniment of puzzled snortings from the neighbor herds.
The herd fell to feeding at once, as if nothing in the least unusual had happened. But Brown Bull, after cropping the sweet, tufted grass for a few minutes, was seized with one of his pangs of apprehension, and raised his head for a fresh survey of the distance. This time he did not resume his feeding, but stood for several minutes shifting his feet uneasily until he had quite satisfied himself that the ponies which he saw emerging from a cleft in the foothills were not a harmless wild troop, but carried each a red rider. He had reached the Indian country, and his place on the flank of the host, as his craft and experience told him, was no longer a safe one.
For a little, Brown Bull stood irresolute, half inclined to lead his followers away from the host and slip back into the wooded foothills whence they had come. Then, either moved by a remembrance of the harsh winter of the north, or drawn by the pull of the host upon his gregarious heart, he lost the impulse. Instead of forsaking the host, he led his herd down the knoll and insinuated it into a gap in the ranks.
Here Brown Bull was undoubtedly a trespasser. But instead of forcing a combat or, rather, a succession of combats, he contented himself with holding his straitened ground firmly rather than provocatively. His towering bulk and savage, resolute bearing made the nearest bulls unwilling to challenge his intrusion. Little by little the herds yielded way, half unconsciously, seeking merely their own convenience. Little by little, also, Brown Bull continued his crafty encroachments, till at length, after perhaps a couple of hours of maneuvering, he had his charges some four or five hundred yards in from the exposed flank and well placed near the front of the march, where the pasturage was still sweet and untrampled.
The Indians, sweeping up on their mad ponies, rode close to the flank of the host and chose their victims at leisure. Killing for meat and not for sport, they selected only young cows in good condition, and were too sparing of their powder to shoot more than they needed. They clung to the host for some hours, throwing the outer fringe of it into confusion, but attracting little attention from the herds beyond their reach. Once in a while some bull, more fiery than his fellows, would charge with blind, uncalculating valor upon these nimble assailants, only to be at once shot down for his hide. But for the most part, none but those herds actually assailed paid much attention to what was going on. They instinctively crowded away from the flying horsemen, the flames and thunder of the guns. But their numbers and the nearness of their companions seemed to give them a stolid sense of security even when the swift death was almost upon them. As for Brown Bull, all this was just what he had expected and made provision against. The assault came nowhere near his own charges, so he treated it as none of his affair.
The Indians withdrew long before nightfall; but the following day brought others, and for a week or more there was never a day without this harassing attack upon one flank or another of the host, or sometimes upon both flanks at once. Again and again, as the outer ranks dwindled, Brown Bull found himself nearing the danger zone, and discreetly on each occasion he worked his herd in a few hundred yards nearer the center.
Then, for a space of some days, the attacks of the Indians ceased, and the wolves and coyotes came back to dog the trail of the diminished host. But Brown Bull was not unduly elated by this respite. He held his followers to their place near the center of the march, and maintained his firm and apprehensive vigilance untiringly. The days were now hot and cloudless, and so dry that the host seemed literally to drink up every brook or pond it passed, and an irritating dust-cloud overhung the rear of the trampling hoofs.
But these few days of peace were but prelude to harsher trial. From somewhere far to the left came now a band of white hunters, who rode around the host and attacked it on both flanks at once. They killed more heedlessly and brutally than the Indians, for the sake of the hides rather than for meat, each man hurriedly marking his own kill and then dashing on to seek more victims. Each night they camped, and in the cool of the morning overtook the slow-moving host on their tireless mustangs. The trail of stripped red carcasses which they left behind them glutted all the wolves, coyotes, and carrion crows for leagues about, and affronted the wholesome daylight of the plains. This visitation lasted for five or six days, and the terror it created spread inwards to the very heart of the host. Gradually the host quickened its march, leaving itself little time for feeding and only enough rest for the vitally essential process of rumination. At last the white marauders, satiated with slaughter, dropped behind, and immediately the host, now shrunken by nearly a third, slackened its pace and seemed to forget its punishment. Phlegmatic and short of memory, the herds were restored to content by a day of heavy rain, which laid the dust, and freshened their hides, and instilled new sweetness into the coarse plains grasses. But Brown Bull's apprehensions redoubled, and he grew lean with watching.
The path of migration—the
