"That's sartin enough," Pearson put in; "but they're a strong tribe, and ef they can harden their hearts and make a rush it's all up with us. I allow that it's contrary to their custom, but when they see no other way to do with, they may try."
"I suppose if they do try a rush," Harold said, "they will do it against this end of the island?"
"Yes, you may bet your money on that," the scout answered. "In other places the rock goes pretty nigh straight up from the water, but here it's an easy landing. Being so close to 'em they're sure to know all about it; but even if they didn't, the chap that got away would tell 'em. I don't much expect an attack to-night—the bands won't be back yet. They'll have a grand palaver to-night, and there'll be a big talk afore they decide what is best to be done; so I think we're safe for to-night. To-morrow we'll set to work and build a shelter for the pretty ones up above, where they'll be safe from stray shots. Then we'll throw up a breastwork with loose rocks on the top of the slope round this cove, so as to give it to 'em hot when they land."
"You have plenty of powder?" Harold asked.
"Dollops," Peter replied; "more'n we could fire away if we was besieged here for a month."
"Then you could spare me twenty pounds or so?"
"We could spare you a whole keg if you like; we've got three full. But what are you thinking of now, young un?"
"I was thinking," Harold answered, "of forming a line of holes, say three feet apart, in the ice across the mouth of the cove. If we were to charge them with powder and lay a train between them, we could, when the first dozen or so have passed the line, fire the train and break up the ice. This would prevent the others following, and give them such a bad scare that they would probably make off, and we could easily deal with those who had passed the line before we fired it."
"That's a good idea of yours, lad. A fust-rate idea. The ice must be a foot thick by this time, and ef you put in your charges eight inches and tamp 'em well down you'll shiver the ice for a long way round. The idea is a fust-rate one."
Pearson and Cameron assisted in the work, and the Indians, when Peter had explained the plan to them, gave deep gutteral exclamations of surprise and approval. The process of blasting was one wholly unknown to them.
