"Atta boy," Jack agreed.

"You look out you don't get lost," their uncle warned them.

"We won't. We'll be back by the time they get back with the baskets," Bob assured him.

The cocoanut trees came to an end before they had gone a hundred feet and they found themselves on the edge of a narrow ravine on the other side of which the land was too high for them to see beyond.

"Let's go up to the top of that hill and see what we can see from there," Jack suggested.

"Think we'll have time?"

"Sure. They won't be back for a half hour at least."

"All right, but make it snappy."

But they were unable to hurry, as the ravine was filled with a peculiar long grass, the edges of which were as sharp as a knife blade and they were obliged to be careful to avoid being cut. But finally, panting and wringing with perspiration, they reached the top of the hill, only to find that another ravine and another hill beyond again shut off their view.

"All that for nothing," Bob panted as he threw himself down on the ground.
