“What fools we were not to mark the trees where we came out,” Kenneth wailed, as they dropped down on the sand, worn out. “We were so glad to get out of the place that we did not think about getting through again.”

“We can’t go around,” Kenneth said, thinking aloud; “the swamp comes right down to the water on all sides of the island but this. I guess we have got to stick it out all night, old man.” Kenneth laid his hand on his friend’s shoulder.

“My, but I’m thirsty!” was the mate’s only comment.

With the suddenness peculiar to the tropics, the sun went down in a blaze of color, and in its stead came a cloud of mosquitoes, bloodthirsty and poisonous. Without protection of any kind, the boys suffered terribly—faces, hands, and feet were soon covered with the itching little spots, that spread until their whole bodies were covered with the bites of the pests. Their thirst increased until their mouths seemed like dry ovens lined with dust and cracked with heat. Hunger, too, assailed them—the hunger of healthy appetites long unappeased, gnawing, and weakening.

Kenneth gathered some half-green wood from the edge of the forest, built a fire, and in the dense smoke they sat as long as they could, or until they choked.

Then, in order that one, at least, might rest, they took turns in brushing the invading mosquitoes from each other. While one rested, the other plied a palm branch; and so they passed the long night—interminable it seemed.

At length the gray dawn began to steal over the sea, and the boys, weak with hunger, and almost frantic with parching thirst, thanked God for it. They knew that with the appearance of the sun the mosquitoes would go, and with the hope that “springs eternal,” longed to begin the search for the path again.

Soon the heavens were lighted with the glory of the sunrise, and the waters, tinged with its colors, heaved and tossed like a great surface of iridescent molten metal—constantly changing, showing new shades that ran into one another, dimpled, flamed, and faded.

Arthur and Kenneth could appreciate the beauty of the scene in a dull sort of way only. They suffered terribly; the pangs of hunger and the tortures of thirst drove all else from their minds.

A plunge in the cool surf, however, freshened them up greatly, though it took all their resolution to resist the temptation to drink the intensely salt water.
