No more words were necessary. Harry and his two mates rode on at a slower pace than before, while the two Indians, Jerry, and Tom dismounted, left their horses beyond the turn, and then coming back took up their positions behind four large boulders. The Indians had noticed their returning figures, for they suddenly drew up their horses and gathered together in consultation.
"Draw your bullet, Tom," Jerry said, "and drop in half a charge more powder; I reckon that piece of yours will send a bullet among them with the help of a good charge. Allow a bit above that top notch for extra, elevation. It's a good big mark, and you ought to be able to plump a bullet among them."
Tom followed the instructions, and then resting the barrel on the top of the boulder took a steady aim and fired. There was a sudden stir among the group of Indians. A horse reared high in the air, almost unseating its rider, and then they all rode off at the top of their speed, and halted two or three hundred yards lower down the valley. The Senecas uttered a grunt of approval.
"That was a good shot, Tom, though I wish you had hit one of the red-skins instead of his critter. Still, it will give them a good lesson, and make them mighty keerful. They won't care about showing their ugly heads within range of a piece that will carry five hundred yards."
A quarter of an hour passed without any movement on the part of the Indians. Then a large party of horsemen appeared from the trees below, and were greeted by them with a yell of satisfaction.
"There must be well-nigh fifty of them," Jerry said. "I reckon it's the party that came down the hill. They must have picked up a good many others by the way. Now the fun is going to begin."
After five minutes' consultation some twenty of the Indians dismounted, and dividing into two parties ascended the slopes of the valley and began to move forward, taking advantage of every stone and bush, so that it was but occasionally that a glimpse of one of their bodies was obtained.
"They are going to skirmish up to us," Jerry said, "till they are near enough to make it hot for us if we show a head above the rocks to fire. As soon as they can do that, the others will charge. I think they are not more than four hundred yards off now, Tom. That is within your range, so you may as well begin to show them that we are awake. If you can bring one down it will check their pace."
Tom had just noticed three Indians run behind a clump of bushes, and he now levelled his rifle so that it bore on a spot a foot on one side of it. Half a minute later an Indian appeared at the bush and began to run forward. Tom pressed the trigger. The Indian ran a few steps, and then fell forward on his face.
"Bravo, Plumb-centre!" Jerry shouted. "We said that you would do the rifle credit, Tom, and Billy the Scout could not have done better himself."
