"Then let's make a start," added Ellerton. "There's no time like the present, so I vote we begin to dismantle the remains of the yawl, examine and overhaul her canvas, and remove the ballast."

"I haven't measured the smallest canoe," remarked Andy. "What's her length, do you think?"

"About twenty-eight feet in length, nine in breadth, and two feet draught, though with the addition of a false keel and ballast she will draw at least four feet."

Accordingly all hands set to work with a will, and ere nightfall the shattered hull of the yawl was a mere shell, the gear being stowed away in the lower storehouse.

"To-morrow we'll make a start with the canoe," said Ellerton, as they prepared to retire for the night. "There are plenty of pieces of timber to shore her up, and wedges can easily be made. Before the end of the week we ought to have her keel and keelson bolted on."

"Then sleep well on it," added Mr. McKay, "for there's much to be done."

The inhabitants of McKay's Island had already made their customary signal with the searchlight, the power had been switched off, and the canvas hood placed over the instrument for the purpose of protecting it from the night dews. This routine was always the last ere the day's work ended.

Mr. McKay was about to close the door of the dwelling-house when a rapid and prolonged ringing of the electric alarm bell broke upon the stillness of the night.

Instantly there was a rush for the arms-rack where the rifles were kept ready for immediate use, and, securing their weapons, the whole party made for the open, Terence, according to a prearranged plan, running to the powerhouse to switch on the current, while the others took up their position at the palisade commanding the cliff-path.

The night was pitch dark; a light breeze ruffled the palm trees, but beyond that all was still. Peering into the darkness the defenders waited, finger on trigger, to open fire on the first appearance of the foe.
