"What does that mean, uncle?" Tom asked, as the chief gave a short exclamation of surprise and anger.
"It means, lad, that the red-skins have been sharper than we gave them credit for. When their spies brought them news that we had started they must have come down to the fire and followed our trail at once with torches, before we had got above an hour or two away. No doubt it was slow work, but they must have found where we changed our course, and made out that we were making for the head of the cañon. I expect most of them lost no time in following the trail farther, but rode straight for the head of the cañon, and like enough they weren't half an hour behind us when we came out. The others rode to the edge of the plateau and set those fires alight."
"But what do they mean, uncle?"
"They are a warning to all the villages that we have headed back, you may be sure of that, though I can't say what the message is, for every tribe has its own signals, but it will have set them on the watch up and down the valley; and like enough the signal has been repeated somewhere at a point where it can be seen straight down the Big Wind Valley. The shooting will tell them all which way we are making, and if the 'Rappahoes have come out of the cañon, as I reckon they have, they need lose no more time in looking for our trail. I reckon in half an hour we shall have a hundred or so of the varmint after us. I only hope there are no more villages upon this line. I don't so much care about the fellows who are following us, we are sure to find some place where we can make a stand, but it would be awkward if we find our way barred."
"But if there is no one in front, uncle, I should think we might be able to keep ahead. Our horses are as good as they are likely to have."
"You and Jerry might be able to, Tom, for you have got hold of two first-rate ponies; but the Indians' are nothing out of the way, and our ponies ain't in it with you; besides, they and the pack-horses have all been doing hard work for the last week with none too much food, and many of the 'Rappahoes will be on fresh horses. I expect we have got some very tall climbing to do before we get up to the pass, and we have got to do our fighting before we get there."
The ground rose steeply, and was encumbered by fallen stones and boulders, and it was not long before the pack-horses began to show signs of distress, while those ridden by Harry and his two comrades were drawing their breath in short gasps. After emerging from the trees the ravine had run in almost a straight line for more than half a mile, and just as they reached the end of this stretch a yell was heard down the valley. Looking back they saw eight or ten mounted Indians emerging from the wood at the lower end.
"That is a signal," Harry exclaimed, as four rifles were fired in quick succession. "Well, we have got a bit of a start of them, and they won't venture to attack us until some more come up. We had better take it a bit quietly, chief, or our horses will give out. I expect we sha'n't be long before we come upon a place where we can make a stand."
The Seneca looked round at the horses. "You, Sam, Ben and pack-horses go on till you get to place where can fight. We four wait here; got good horses, and can ride on. We stop them here for a bit."
"That would be best. I don't like being out of it, but we will do our share presently."
