"Wake up Paul and Tom and tell 'em the time has come."
In an instant all four were crouching beside the opening, their rifles ready. The extra rifle that Henry had brought in was lying loaded at his feet, and all the while the wolf on the far ridge, moving from place to place, whined and howled incessantly. Despite Henry's knowledge of its source it made his hair rise a little, and a quiver ran along his spine. What then must be its effect upon red men, who were so much more superstitious than white men? They might think it the spirit of some great forgotten warrior that had gone into a wolf which was now giving warning.
Nevertheless he listened with all the power of his hearing for what might happen closer by, and presently he heard a rustling in the grass that was not caused by the wind. A moment later, and the rustling came from a second point and then a third. As he had surmised, Red Eagle had spread out his men until they were advancing like the spokes of a wheel toward a hub, the hub being the mouth of the cavern. And from the far ridge the warning cry of the wolf never ceased to come.
"Do you hear them creeping?" whispered Henry to Ross.
Silent Tom nodded and shoved forward the muzzle of his rifle.
"They'll be on us in a minute," he whispered back.
Paul and Long Jim had heard and they too made ready with their rifles. But all of them relied now on Henry, whose hearing was keenest. The faint, sliding sounds ceased, and he knew that the warriors had stopped to listen for their enemies, hoping to catch them off guard. The howling of the wolf also ceased suddenly, and the wind was again supreme.
At least ten minutes passed in almost intolerable waiting, and then Henry heard the renewal of the faint sliding sounds, coming from many points.
"Be ready," he whispered to his comrades. "When they're near enough they'll all jump up, utter a mighty yell and rush for us."
The rustlings came closer, then they ceased all at once, there was a half minute of breathless silence, and the air was rent by a tremendous war whoop, as twenty warriors, springing up, rushed for the opening. Henry fired straight at the heart of the first man, and snatching up the second rifle sent a bullet through another. The other three fired with deadly aim and all the assailants fell back, save one who, standing on the very edge of the opening, whirled his tomahawk preparatory to letting it go straight at Henry's head. But a moment before it could leave his hand a rifle cracked somewhere and he fell dead, shot through the head, his figure lying directly across the entrance. From the other Indians came a yell of rage and dismay, and then after a groan or two somewhere in the grass, all were gone.
