"I've been used to a sailing boat ever since I was a kid. Also I've brought my share of the grub and a bit over."

Burgoyne capitulated without further protest. Mostyn's declaration that he knew how to sail a small boat more than wiped out the objection.

"All right," he said; then addressing Branscombe and Twill—the third member of the shore party—he continued: "It's no use hanging on to the slack any longer. We've found a water-tank and it wants filling. Mostyn, you might put all the provisions and spare gear on board. Yes, the canvas tanks. They may come in handy."

With four men to handle the tank the task of conveying it filled with water to the boat was a fairly simple one. Under Burgoyne's direction it was stowed between two of the thwarts and immediately for'ard of the centre-board case.

"That's everything, I think," remarked Alwyn. "Now the sooner we're off the better. I want to get at least thirty miles from the island before dawn. Now, Phil, if you will kindly bring Miss Vivian—I mean Young Bill—we'll put off."

Branscombe carried out instructions. Hilda Vivian wearing an old pilot coat (a gift from Captain Davis) over her borrowed clothes, which during her stay on the island consisted of a duck jumper and trousers and a sailor's straw hat, came up to greet Alwyn.

"I'm ready, Mr. Burgoyne," she said; then with a suspicion of a smile she added, "and may I keep my face clean now, please?"

She shook hands and said good-bye to Branscombe and Twill, and was assisted by Alwyn into the boat.

Slipping into the stern sheets Burgoyne gave the word to push off, and the voyage began.

Hilda Vivian was told to sit down upon a pile of canvas in front of the water-tank, where she would be least in the way when the time came to step the mast and hoist sail. Mostyn was pulling bow oar and Minalto stroke. Burgoyne steered, the while keeping an anxious eye upon the cliffs fronting the still hidden Observation Hill.
