"But they must be here somewhere," cried Peter, "and there must be more diamonds where you found those! I'll certainly come up here next summer and try my own luck."

"I've thought of doing so myself; that is, if this lot turns out to be any good. But getting back to town is the present problem, and we've got to consider how to recapture the cabin and your outfit of supplies."

"But not before we eat again," said Fred.

Macgregor, who was as famished as any of them, consented, and they prepared such a banquet as the three castaways had not seen since they left the cabin. It almost exhausted the supplies that Horace had brought, but it did them all a great deal of good. With a new feeling of being able to grapple with the problem, they settled down to consider the question of war.

"We might set fire to the cabin," Fred suggested, "and try to capture the fellows when they rush out."

"Out of the question," declared Peter, "for, even if it worked, the provisions would be burned up. I had thought of stopping up their chimney during the night. The smoke would suffocate them in their sleep, and we could go in and drag them out insensible."

"I am afraid it would waken them first," said Horace. "We'd have them coming out with rifles. Now I'd been thinking that if we only had some of your formaldehyde fumigator we could get them under control very easily."

"So we could. A can of that stuff let through the roof would put them into a dead stupor without waking them. The only risk would be that of killing them all outright. There was a can of it left, too, but it's in the cabin."

"No, it isn't!" cried Fred. "I put it outside in a hollow tree, so as not to have the stuff in the house. I could get it in ten minutes."

"Fred, you're a diamond yourself!" Peter exclaimed. "If it's as you say, we'll have them out of that cabin in a jiffy."
