“Isn’t this worth working for?” inquired the captain, as he swept his hand round, tracing the horizon line.

Off in the distance lay the Bird Islands, and still further the Breton Islands showed faint and hazy in the fast deepening dusk. The wind was a mere caressing zephyr, and the sea rolled in good-naturedly, soothingly, even.

“What’s the matter with this, boys? Let’s anchor here. Heave the lead, Frank, and see if it’s all right.”

Frank reached under the cockpit seat and took from its rack the lead and line. “Aye, aye, sir,” he answered, in mock servility. Hooking his left arm round the port stays, he stood on the rail, the long strip of lead dangling from his right hand; the left hand held the coil of line. For a minute he stood poised there while the “Gazelle” curtseyed her acknowledgments to the long swells, a picturesque figure silhouetted against the warm glow of the setting sun. Then he began to swing his right arm slowly and steadily, the lead just clearing the water. When it was swinging well forward he let it go, and as the line slipped through his fingers he watched for the bits of colored cloth that indicated the depth. Down, down it went, until all but the leather strips had disappeared in the water. Then the line slackened, and the leadsman knew that bottom had been reached. Beginning to pull in the line Frank shouted, “Three fathoms!”

“Stand by! Let go your anchor!” ordered Kenneth, as soon as Frank had reeled in the lead-line.

“Let her go!”

There was a splash, then a hum and swish of heavy rope as the anchor cable whipped through the chocks.

“Let go your mizzen halliards!” The creak of the blocks told that the order had been obeyed. Arthur let the jigger go at the same time. For a few minutes not a word was spoken—all the mouths were full of cotton rope—“stops”—while the hands were busy tightly rolling the sails. The jib was furled up at last, and not till the anchor light was set glowing, hung from the triced-up jib four or five feet above the deck, did the four boys have time to lay off and enjoy the situation. They were surprised to see how dark it was. Only a minute ago it seemed that the sky was alight and full of color; but now only a faint soft glow remained as a reminder that they were near the tropics where the sun drops out of sight while still glowing.

Arthur and Kenneth lay on their backs on the cabin roof, while Frank went below to get supper. Both boys murmured their content. They were a little tired, for the navigation of Cubit’s Gap had been a strain on the nerves and had necessitated more or less violent exertion. The air was warm and restful; the motion of the boat was like the easy rocking of a cradle, the most delightful motion on earth; the stars were just beginning to show themselves, and the mast of the boat seemed to point them out one by one as she swung to and fro. Suddenly there was a slight splash alongside and a long-drawn, vociferous sigh.

“What was that?” Arthur said, sitting up quickly, with a startled look on his face.
