Leo seized the rifle. Almost without taking time to aim, he fired and shot the bird dead.

“There,” said he, laughing, “but I suspect it is a lost goose after all. It will be hard work to get either of these birds, uncle. However, I’ll try.”

Leo was proceeding to strip when the Captain forbade him.

“Don’t trouble yourself, lad,” he said, “I’ll go for them myself.”

“You, uncle?”

“Ay, me. D’ye suppose that nobody can swim but you and Benjy? Here, help me to open this box.”

In silent wonder and expectation Leo and Benjy did as they were bid. When the mysterious packing-case was opened, there was displayed to view a mass of waterproof material. Tumbling this out and unrolling it, the Captain displayed a pair of trousers and boots in one piece attached to something like an oval life-buoy. Thrusting his legs down into the trousers and boots, he drew the buoy—which was covered with india-rubber cloth—up to his waist and fixed it there. Then, putting the end of an india-rubber tube to his mouth, he began to blow, and the buoy round his waist began to extend until it took the form of an oval.

“Now, boys,” said the Captain, with profound gravity, “I’m about ready to go to sea. Here, you observe, is a pair o’ pants that won’t let in water. At the feet you’ll notice two flaps which expand when driven backward, and collapse when moved forward. These are propellers—human web-feet—to enable me to walk ahead, d’ye see? and here are two small paddles with a joint which I can fix together—so—and thus make one double-bladed paddle of ’em, about four feet long. It will help the feet, you understand, but I’m not dependent on it, for I can walk without the paddles at the rate of two or three miles an hour.”

As he spoke Captain Vane walked quietly into the water, to the wild delight of Benjy, and the amazement of his nephew.

When he was about waist-deep the buoy floated him. Continuing to walk, though his feet no longer touched ground, he was enabled by the propellers to move on. When he had got out a hundred yards or so, he turned round, took off his hat, and shouted—“land ho!”
