The man on watch now gave a shout. "I can see them," he said.

"How many of them?"

"I guess there is about eighty. There is a thick clump in the middle, I reckon that they are the soldiers, and thirty or forty riding loose; I allow they are cow-boys."

"That is just about the right number," Harry said; "if there was more of them the Indians wouldn't fight. I don't know as they will now, but seeing as there must be three hundred of them, I expect they will try it. Now, then, up with these branches."

In a quarter of an hour the branches were all hauled out of the gap. While this had been going on the women had given a feed and a good drink of water to the horses, for there was no occasion any longer to husband their resources. The animals were now saddled and led down through the gap. By this time the Indians were all mounted, and were moving in a close body across the plain to meet the advancing foe.

"Now, Jim," Broncho Harry said, "you stand on the edge, and when you see the fight begin you wave your hand. We can't make a start until they are at it, and we sha'n't be able to see down below there."

The cow-boys made their way down to the plain and then mounted. They sat for ten minutes with their eyes fixed upon Jim Gattling. Presently he waved his arm, and with a shout they started at a gallop. As soon as they were fairly out on the plain they heard the sound of fire-arms, and after galloping half a mile came suddenly in view of the combat. The Indians had boldly closed with the troops and cow-boys, who were now driven together. A desperate hand-to-hand conflict was raging. Swords flashing in the sun, waving tomahawks, and spears could be seen above the mass. The cracking of revolvers was incessant, and a light smoke hung over the conflict.

"They are hard at it, boys," Long Tom exclaimed; "now don't shout until we are on them. They are too busy to notice us. Keep well together, and we shall go through them like a knife."

Not a word was spoken as they galloped down upon the scene of conflict. When they were within a hundred yards a cry of warning was raised, and some of the Indians faced round; but in a moment, with a loud shout, the band of cow-boys charged down upon them and cleft their way into the mass, horse and rider rolling over under the impetus of the onslaught. The deadly six-shooters spoke out, while the Indians fell thickly around them; and in a minute they had joined the whites in the centre of the mass. There was a shout of welcome, and then the officer commanding the troops cried:

"Now is your time, lads; press them hard, give it them hot!" and the united party attacked the Indians with fresh vigour.
