"It's nothing to laugh at," said Mary severely. "You may be very ill by and by."

"Meanwhile put the rest of the fish where the flies and insects can't get at it," said Elizabeth. "There's a nice little hollow in that rock over there. Cover it with leaves."

This done, they sat one on each side of Elizabeth, propping their chins on their hands, and gazing at her with mournful interest.

"This is too absurd," said Elizabeth, after a few minutes. "Let us get on with our hut. I can't stand being stared at like this. Come along, girls. We must cut down some more canes to make walls; I'll show you what I mean."

They went up-stream to the clump of canes, and, selecting some of the longest, proceeded to hack them down with their knives—no easy task, for the longest canes were also the thickest. But after a little trouble they got three or four that Elizabeth thought would answer her purpose, and took them to the site chosen for the hut. Here they laid the canes across the projecting branches of the three trees, binding them firmly in place with strong tendrils of a creeping plant. After an hour's work all the canes were in position, forming a kind of framework for the roof.

"Now all we have to do is to cover this with matting, and our roof is finished," said Elizabeth. "We shall have to get some more canes to stretch matting on for the walls, and as we have used up nearly all the grasses we collected, we had better go at once to get some more ready for to-morrow."

"To-morrow!" cried Mary. "I'd forgotten! Do you feel quite well, Bess?"

"As well as possible."

"How long is it since you ate the fish?" asked Tommy.

"More than two hours—long enough for the poison to act, I'm sure. So we may make up our minds that the fish is perfectly wholesome, and there's baked fish for supper for all of us to-night."
