In the short interval of almost perfect darkness which preceded the moonlight, and taking advantage of one of the frequent squalls of wind which howl down the narrow gorges of the mountains, these two determined men, with footsteps noiseless as the panther's, crawled to the edge of the little plateau of some hundred yards' square, where the five Indians in charge of the animals were seated round the fire, perfectly unconscious of the vicinity of danger. Several clumps of cedar bushes dotted the small prairie, and amongst these the well-hobbled mules and horses were feeding. These animals, accustomed to the presence of whites, would not notice the two hunters as they crept from clump to clump nearer to the fire, and also served, even if the Indians should be on the watch, to conceal their movements from them.

This the two men at once perceived; but old Killbuck knew that if he passed within sight or smell of his mule, he would be received with a hinny of recognition, which would at once alarm the enemy. He therefore first ascertained where his own animal was feeding, which luckily was at the farther side of the prairie, and would not interfere with his proceedings.

Threading their way amongst the feeding mules, they approached a clump of bushes about forty yards from the spot where the unconscious savages were seated smoking round the fire; and here they awaited, scarcely drawing breath the while, the moment when the moon rose above the mountain into the clear cold sky, and gave them light sufficient to make sure their work of bloody retribution. Not a pulsation in the hearts of these stern determined men beat higher than its wont; not the tremour of a nerve disturbed their frame. With lips compressed, they stood with ready rifles, the pistols loosened in their belts, and scalp-knives handy to their gripe. The lurid glow of the coming moon already shot into the sky above the ridge, which stood out in bolder relief against the light; and the luminary herself was just peering over the mountain, illuminating its pine-clad summit, and throwing its beams on an opposite peak, when Killbuck touched his companion's arm, and whispered, "Wait for the full light, boy."

At this moment, however, unseen by the trapper, the old and grizzled mule had gradually approached, as it fed along the plateau; and, when within a few paces of their retreat, a gleam of moonshine revealed to the animal the erect forms of the two whites. Suddenly she stood still and pricked her ears, and stretching out her neck and nose, snuffed the air. Well she knew her old master.

Killbuck, with eyes fixed upon the Indians, was on the point of giving the signal of attack to his comrade, when the shrill hinny of his mule reverberated through the gorge. The next instant the Indians were jumping to their feet and seizing their arms, when, with a loud shout, Killbuck, crying, "At 'em boy; give the niggurs h——!" rushed from his concealment, and with La Bonté by his side, yelling a fierce war-whoop, sprang upon the startled savages.

Panic-struck with the suddenness of the attack, the Indians scarcely knew where to run, and for a moment stood huddled together like sheep. Down dropped Killbuck on his knee, and stretching out his wiping stick, planted it on the ground to the extreme length of his arm. As methodically and as coolly as if about to aim at a deer, he raised his rifle to this rest and pulled the trigger. At the report an Indian fell forward on his face, at the same moment that La Bonté, with equal certainty of aim and like effect, discharged his own rifle.

The three surviving Indians, seeing that their assailants were but two, and knowing that their guns were empty, came on with loud yells. With the left hand grasping a bunch of arrows, and holding the bow already bent and arrow fixed, they steadily advanced, bending low to the ground to get their objects between them and the light, and thus render their aim more certain. The trappers, however, did not care to wait for them. Drawing their pistols, they charged at once; and although the bows twanged, and the three arrows struck their mark, on they rushed, discharging their pistols at close quarters; La Bonté throwing his empty one at the head of an Indian who was pulling his second arrow to its head at a yard distance, and drawing his knife at the same moment, made at him.

But the Indian broke and ran, followed by his living companion; and as soon as Killbuck could ram home another ball, he sent a shot flying after them as they scrambled up the mountain side, leaving in their fright and hurry their bows and shields on the ground.

The fight was over, and the two trappers confronted each other: "We've given 'em h—!" laughed Killbuck.

"Well, we have," answered the other, pulling an arrow out of his arm.—"Wagh!"
