But as the boys busied themselves with their work on the hut, their minds were occupied and their anxiety as to Dunbar was less than during the night before.

When another day had passed, however, and still Dunbar did not return, that anxiety became very keen indeed. They built their fire again on the bluff, and they tried hard to sleep by it, but with little success. They would resolve to stop talking and go to sleep, and for a few minutes all would be quiet. Then one after another would grow restless and sit up, or walk about, or say something that set the talk going again.

Presently, when all had given up the attempt to sleep, Larry made a final end of all efforts in that direction by saying:

“You see, boys, this thing is really very serious. We are all anxious about Mr. Dunbar’s safety, but we’ve got our own to think about also.”

Every one of the company had thought of that, but until now all of them had avoided mentioning it.

“You see it isn’t Mr. Dunbar alone that is missing; the dory is gone too, and if he doesn’t return the dory won’t.”

“No, and in that case,” commented Dick, “our situation will be really very serious. We are here on what is practically an island that nobody ever visits; we are without a boat, and there is no possible way of escape from here without one.”

“Can’t we build some sort of craft that will answer our purpose?” asked Tom, hopefully.

“What with?” Larry responded. “We have no materials and no tools except the one little ax. There isn’t so much as a nail anywhere on Quasi plantation, and if there were kegs full, we haven’t a hammer to hit them with.”
