But the visitors had not waited for him. With one impulse they had ridden straight into the horse corral, had thrown off saddles and bridles from their steaming mounts, and, every man for himself, had chosen afresh from the ranch herd. Passing out in single-file through the gate, they came upon Grey; but still they did not stop. The one word "rustler" was sufficient password, and not five minutes from the time they arrived they were again on the way, headed straight southwest for their long ride to the river.
Hour after hour they forged ahead. The mustangs had long since puffed themselves into their second wind, and, falling instinctively into their steady swinging lope, they moved ahead like machines. The country grew more and more rolling, even hilly. From between the tufts of buffalo grass now and then protruded the white face of a rock. Over one such, all but concealed in the darkness, Grover's horse stumbled, and with a groan, the rancher beneath, fell flat to earth. By a seeming miracle the man arose, but the horse did not, and an examination showed the jagged edge of a fractured bone protruding through the hide at the shoulder. There was but one thing to do. A revolver spoke its message of relief, a hastily-cast lot fell to McFadden, and without a word he faced his own mount back the way they had come, assisted Grover to a place behind him, turned to wish the others good luck, and found himself already too late. Where a minute ago they had been standing there was now but vacancy. The night and the rolling ground had swallowed the avengers up as completely as though they had never existed; and the Scotchman rode slowly back.
It was yet dark, but the eastern sky was reddening, when they reached the chain of bluffs bordering the great river. They had made their plans before, so that now without hesitating they split as though upon the edge of a mighty wedge, half to the right, half to the left, each division separating again into its individual members, until the whole, like two giant hands whereof the cowboys, half a mile apart from each other, were the fingers, moved forward until the end finger all but touched the river itself.
Still there was no pause. The details had been worked out to a nicety. They had bent far to the south, miles farther than any man aiming at the Wyoming border would have gone, and now, having arrived at the barrier, they wheeled north again. It was getting daylight, and cowboy Pete,—in our simile the left little finger,—first to catch sight of the surface of the stream, waved in triumph to the nearest rider on his right.
"We've got him, sure!" he yelled. "She's open in spots"; and though the others could not hear, they understood the meaning, and the message went on down the line.
On, on, more swiftly now, at a stiff gallop, for it was day, the riders advanced. As they moved, first one rider and then another would disappear, as a depression in the uneven country temporarily swallowed them up—but only to reappear again over a prominent rise, still galloping on. They watched each other closely now, searching the surrounding country. They were nearing a region where they might expect action at any moment,—the remains of a camp-fire, a clue to him they sought,—for it was on a line directly west of the Big B ranch.
And they were not to be disappointed. Observing closely, Stetson, who was nearest to Pete, saw the latter suddenly draw up his horse and come to a full stop. At last the end had arrived—at last; and the rancher turned to motion to his right. Only a moment the action took, but when he shifted back he saw a sight which, stolid gambler as he was, sent a thrill through his nerves, a mumbling curse to his lips. Coming toward him, crazy-scared, bounding like an antelope, mane flying, stirrups flapping, was the pony Pete had ridden, but now riderless. Of the cowboy himself there was not a sign. Stetson had not heard a sound or caught a motion. Nevertheless, he understood. Somewhere near, just to the west, lay death, death in ambush; but he did not hesitate. Whatever his faults, the man was no coward. A revolver in either hand, the reins in his teeth, he spurred straight for the river.
It took him but a minute to cover the distance—a minute until, almost by the rivers bank, he saw ahead on the brown earth the sprawling form of a dead man. With a jerk he drew up alongside, and, the muzzles of big revolvers following his eye, sent swiftly about him a sweeping glance. Of a sudden, three hundred yards out, seemingly from the surface of the river itself, he caught a tiny rising puff of smoke, heard simultaneously a sound he knew so well,—the dull spattering impact of a bullet,—realized that the pony beneath him was sinking, felt the shock as his own body came to earth, and heard just over his head the singing passage of a rifle-ball.
Unconscious profanity flowed from the rancher's lips in a stream; but meanwhile his brain worked swiftly, and, freeing himself, he crawled back hand over hand until a wave in the ground covered the river from view; then springing to his feet he ran toward the others, approaching now as fast as spurs would bring them, waving, shouting a warning as he went. Within a minute they were all together listening to his story. Within another, the rifles from off their saddles in their hands, the ponies left in charge of lank Bob Hoyt, the eight others now remaining moved back as Stetson had come: at first upright, then, crawling, hand over hand until, peeping over the intervening ridge, they saw lying before them the mingled ice patches and open running water of the low-lying Missouri. Beside them at their left, very near, was the body of Pete; but after a first glance and an added invective no man for the present gave attention. He was dead, dead in his tracks, and their affair was not with such, but with the quick.
At first they could see nothing which explained the mystery of death, only the forbidding face of the great river; then gradually to one after another there appeared tell-tale marks which linked together into clues.
