“We could make it to-night,” replied the Commander, to whom Mr. Pauling had addressed the last query, “but I’d prefer to slow down and make it by daybreak--its a mere speck and scarcely ten feet above water and there’s a risk in running for it in the dark.”

“Yes, by all means, wait for dawn,” assented Mr. Pauling. “We could accomplish nothing at night and if there are men there, our lights might warn them.”

Accordingly, the destroyer slowed down and with the vast bulk of Guadeloupe stretching for miles along the eastern horizon, the little vessel slid easily through the sea towards her goal. As usual, Bancroft or one of the boys constantly listened at the radio receivers, but no sounds, save the messages passing between two distant merchant ships, came in.

With the first faint streaks of light upon the eastern sky, the destroyer picked up speed and tore southward for the tiny speck of land that lay below the horizon ahead. The forward gun was manned and ready for emergencies; the two boys and their companions peered anxiously through the gray dawn for a first glimpse of the sought-for islet, and all thrilled with expectancy and excitement.

“There ’tis!” cried Rawlins, who was the first to catch a glimpse of the tiny gray smudge that broke the even level of the sea’s rim.

Instantly, all glasses were focused on the spot and rapidly it rose and took form as a low, flat-topped bit of land, rimmed with white surf and with clouds of sea birds wheeling above it. So low was the island that within half an hour of first sighting it, the destroyer was as close to it as the Commander dared approach and all were anxiously searching the desolate spot for some sign of life or of the plane.

“Looks as if your hunch were wrong for once, Rawlins,” said Mr. Pauling. “I don’t see a sign of anything but bare rock and birds.”

“Well, it’s all-fired funny,” declared the diver, “but I’m not sure even yet. Maybe the plane’s on the other side of the island or in some cove. I won’t be satisfied until I’ve searched every inch of the place.”

But when, a few minutes later, they landed upon this isolated, almost unknown bit of forsaken land and were almost deafened by the screams, cries, and protests of the countless thousands of gulls, terns, gannets, pelicans and boobies that made it their home, the island seemed absolutely devoid of all traces of human beings. Rawlins, however, insisted there was no other place where the sea plane could have found a resting place for the night and he searched here, there and everywhere.

Finally, when the party had almost completed the circuit of the little ten-acre spot, the diver, who was in advance, gave a shout.
