"Couldn't we save that as a last resort?" he ventured. "I think that perhaps I might creep up on that fellow without his seeing me."
"But how?" asked Melton in surprise. "You'd have to be as quick as a coyote and as light as a cat to do it. What's your idea?"
"Why," replied Bert, "I figure that we might go back to the place where we first saw him. You can see from the listless way he looked around that he isn't really on the alert. Then too, he's drinking. If we find that he's facing our way, I'll make a circuit and get back of him. Then at the right second I'll make my dash. He probably won't hear me until I get close to him, and then he'll be so paralyzed, what with the surprise and the drink, that I'll have my hands on his throat before he can make a sound. In the meantime, you keep him covered with your knife, and if he sees me too soon you can let fly."
Melton, a man used to quick decisions, spent only a moment weighing the pros and cons, looking keenly at Bert the while. What he saw seemed to satisfy him.
"It's a plucky stunt," he said, "but you're the lad to do it if any one can. I'd sure like to make that fellow talk before he goes over the great divide. Come along."
Noiselessly, they reached their former point of observation. The sentinel still sat there facing their way. The flask was in his hand and they could see from the way he tilted it that it was nearly empty. His carbine stood with its butt on the ground and the muzzle resting against the stump. Crouching low in the thicket, Melton drew his knife from its sheath, his eye gauging the distance. Bert, who had shed his coat and shoes, with a parting pat from Tom, made a wide circuit to the left, creeping along with his body close to the ground and scarcely daring to breathe. Once a twig cracked beneath his hand and his heart seemed to stop beating. But no sound came from the unsuspecting sentry, and after a moment's pause he went on. Soon he reached a point about a hundred feet in the rear of the Mexican, and behind the shelter of a huge tree rose slowly to his feet.
For forty feet the undergrowth was thick enough to conceal him. But then came the little clearing where for sixty feet no concealment was possible. He did not dare to tiptoe over it, because, if he were seen he could not get under way fast enough to reach his quarry. It must be a lightning dash. Once he had run a hundred yards—three hundred feet—in ten seconds flat. That would give him three seconds or less to cross the clearing. But a bullet could travel faster still. He drew a long breath and then, as lightly and swiftly as a panther, he leaped over the intervening space.
He had covered half the distance when the sentry heard him and sprang to his feet. For the fraction of a second he stood, petrified with surprise and fright. Then he reached for his carbine, but as though realizing that he could not level it in time, he abandoned that idea and snatched at his knife. And just then Bert launched himself on him like a thunderbolt.
Down they went fighting like wildcats. They rolled over and over. Bert's hands were on the rascal's throat and he could not utter a cry. But his knife was out and upraised to strike, when Tom, who with Melton had rushed from the bushes the moment the clash had come, grasped the uplifted hand and wrenched it until the knife fell to the ground. Another instant, and the scoundrel, bound with his own belt and gagged with a portion of the serape torn from his shoulders, was sitting huddled up on the ground, with his back against the stump, while baffled rage and hate glowed from his wicked eyes.
"Good work, my boy, good work," said Melton, as he grasped Bert's hand warmly. "You tackled that fellow like a ton of brick. I never saw a prettier rough house than that was for a minute. Now get your breath back while I try to get this fellow to listen to reason. I know this breed of cattle pretty well and I have a hunch that it won't be long before we understand each other."
