"Yes," assented Andy. "But it can't be helped. Look here, Terence, now we are going through a patch of broken water. I can see it a mile or so ahead. We may have a few seas on board, so lash yourself to this cleat and stand by with the bucket. You may have to bale for all you're worth."

Terence closed the cabin-doors. Fortunately they were close-fitting and comparatively watertight; but, on the other hand, the cockpit was not a self-emptying one. Whatever quantity of water broke over had to be baled out.

"We'll have one of those cans of kerosene out of that locker," continued Andy.

"Going to start the motor?"

"No; to throw oil on the sea. Kerosene's not very heavy, but it's all we have. Now, stand by, here it comes."

Only a mile now separated the yawl from the entrance to the lagoon of McKay's Island, but every yard of that mile was beset with dangers.

Andy gripped the tiller, and braced himself for the ordeal. He had been the chief workman in the task of converting the boat into her present form, and now his handiwork was to be put to the test. A faulty piece of wood, a defective screw, an unsound rope—and their lives would have to answer for it.

With a dull roar a white-crested wave broke over the fore-deck, burying the little yawl as far as the mainmast; then ere she could recover herself another comber came like a cataract over the lee quarter. Well it was that both lads had taken the precaution of lashing themselves on, otherwise they might have been swept clean out of the well.

Andy, wellnigh breathless—for he had been hit in the side by the tiller as the boat attempted to broach to—retained sufficient presence of mind to thrust the helm up and enable the craft to meet the next following wave stern on.

"Bale!" he shouted. "Bale for your life!" and seizing the kerosene can that was floating from side to side of the cockpit, he splayed a quantity of oil over each quarter.
