"Look here, boys," Harry said, reining up his horse at a point within two hundred yards of the lower end, "we can't do better than fix ourselves here. An hour's work will get up a wall that will puzzle the red-skins to get over, and there is the advantage that a shot fired here by the guard will bring our whole force up in a couple of minutes. I vote we ride the horses down to the river and let them pick up what they can, and then come back here and build the wall. It will be getting dark in an hour's time, and we may as well finish that job at once. Ben and Sam, you may as well pick out a couple of young fir-trees and bring them down at once, then there will be no time lost. Five of us will be enough for the wall. Keep your eyes open. Likely enough there is a bear or two about, and it would be a great thing for us to lay in a stock of meat before we start."
As soon as they issued from the gorge the horses were unsaddled and the stores taken off the pack-animals. As they were doing this Harry said a few words in a low tone to Sam. He then carefully examined the trees, and picked out two young firs. Sam and Ben took their axes, and the other five went up the gorge again, and were soon hard at work collecting boulders and piling them in a wall.
"There is a gun, uncle," Tom exclaimed presently.
"Well, I hope they have got sight of a bear, we shall want a stock of meat badly."
A dozen shots were fired, but Tom thought no more of it as he proceeded with his work. The bottom of the cañon was but fifteen feet wide, and by the time it was dark they had a solid wall across it nearly six feet high, with places for them to stand on to fire over.
"Now then, Tom, you may as well take post here at once. I will send Sam or Ben up to watch with you. I don't think there is a shadow of chance of their coming to-night, but there is never any answering for red-skins. I would leave Hunting Dog with you, but we shall want him to help make the framework for the canoes; the Indians are a deal handier than we are in making lashings. I will send your supper up here, lad, and your buffalo robes. Then you can take it by turns to watch and sleep. I reckon we shall be at work all night; we have got to get the job finished as quick as we can."
A quarter of an hour later Sam Hicks came up.
"Have you got the trees down, Sam?"
"Lor' bless you, it didn't take a minute to do that. We got them down and split them up, then lit a fire and got the meat over it and the kettle, and mixed the dough."
"Did you kill another bear? We heard you firing."
