All night he ran, on and on in the darkness, stopping only to listen tremblingly to the echo of his own hoofs and to sniff suspiciously at the crouching shadows of innocent bushes. By morning he had left the Bar L outfit many miles behind, and when the red sun rolled up over the edge of the prairie he saw that he was alone in a field that stretched unbroken to the circling sky-line.
Not until noon did the runaway black scent water. Half mad with thirst he dashed to the edge of a muddy little stream and sucked down a great draught. As he raised his head he saw standing poised above him on the opposite bank, with ears laid menacingly flat and nostrils aquiver in nervous palpitation, a buckskin-colored stallion.
Snorting from fright the black wheeled and ran. He heard behind him a shrill neigh of challenge and in a moment the thunder of many hoofs. Looking back he saw fully a score of horses, the buckskin stallion in the van, charging after him. That was enough. Filling his great lungs with air he leaped into such a burst of speed that his pursuers soon tired of the hopeless chase. Finding that he was no longer followed the black grew curious. Galloping in a circle he gradually approached the band. The horses had settled down to the cropping of buffalo grass, only the buckskin stallion, who had taken a position on a little knoll, remaining on guard.
The surprising thing about this band was that each and every member seemed riderless. Not until he had taken long up-wind sniffs was the thoroughbred convinced of this fact. When certain on this point he cantered toward the band, sniffing inquiringly. Again the buckskin stallion charged, ears back, eyes gleaming wickedly and snorting defiantly. This time the black stood his ground until the buckskin's teeth snapped savagely within a few inches of his throat. Just in time did he rear and swerve. Twice more—for the paddock-raised black was slow to understand such behavior—the buckskin charged. Then the black was roused into aggressiveness.
There ensued such a battle as would have brought delight to the brute soul of a Nero. With fore-feet and teeth the two stallions engaged, circling madly about on their hind legs, tearing up great clods of turf, biting and striking as opportunity offered. At last, by a quick, desperate rush, the buckskin caught the thoroughbred fairly by the throat. Here the affair would have ended had not the black stallion, rearing suddenly on his muscle-ridged haunches and lifting his opponent's forequarters clear of the ground, showered on his enemy such a rain of blows from his iron-shod feet that the wild buckskin dropped to the ground, dazed and vanquished.
Standing over him, with all the fierce pride of a victorious gladiator showing in every curve of his glistening body, the black thoroughbred trumpeted out a stentorian call of defiance and command. The band, that had watched the struggle from a discreet distance, now came galloping in, whinnying in friendly fashion.
Black Eagle had won his first fight. He had won the leadership. By right of might he was now chief of this free company of plains rangers. It was for him to lead whither he chose, to pick the place and hour of grazing, the time for watering, and his to guard his companions from all dangers.
As for the buckskin stallion, there remained for him the choice of humbly following the new leader or of limping off alone to try to raise a new band. Being a worthy descendant of the chargers which the men of Cortez rode so fearlessly into the wilds of the New World he chose the latter course, and, having regained his senses, galloped stiffly toward the north, his bruised head lowered in defeat.
Some months later Arizona stockmen began to hear tales of a great band of wild horses, led by a magnificent black stallion which was fleeter than a scared coyote. There came reports of much mischief. Cattle were stampeded by day, calves trampled to death, and steers scattered far and wide over the prairie. By night bunches of tethered cow ponies disappeared. The exasperated cowboys could only tell that suddenly out of the darkness had swept down on their quiet camps an avalanche of wild horses. And generally they caught glimpses of a great black branded stallion who led the marauders at such a pace that he seemed almost to fly through the air.
This stallion came to be known as Black Eagle, and to be thoroughly feared and hated from one end of the cattle country to the other. The Bar L ranch appeared to be the heaviest loser. Time after time were its picketed mares run off, again and again were the Bar L herds scattered by the dash of this mysterious band. Was it that Black Eagle could take revenge? Cattlemen have queer notions. They put a price on his head. It was worth six months wages to any cowboy who might kill or capture Black Eagle.
