"Why not to-day? Ellerton and you can do so while we are making our midday trip back to the house."

Accordingly, instead of ascending the tunnel with Mr. McKay and Terence, the two chums clambered up the face of the cliff. At the top they found that the land sloped steeply towards the peak, the ground being thickly covered with stunted bushes and occasional clumps of palms.

"Look here, Hoppy," remarked Andy, as they sat down to recover their breadth after their fatiguing climb. "It's all very well living on an island when everything goes well, but we can't say that it is now. Perhaps it's a useless fear, but I fear that there's always the possibility of those savage brutes coming back here in overwhelming numbers and wiping us out. That does not tend to make things comfortable, although it may tend to liven things up."

"But they had such a terrible smashing last time," replied Ellerton.

"True! But didn't we give them a good licking when they pursued us in their canoes? That didn't prevent them repeating their unwelcome attentions."

"I hope you don't mean to show the white feather, Andy?"

"Not I. If there's a dust-up, I'll do my best; but, at the same time, I shan't be sorry to get the yawl repaired and say good-bye to the island. The treasure can wait till we charter a steamer to fetch it."

"Well, the savages haven't returned, so we can still make the best of things," replied Ellerton cheerfully. "But we must be moving or we'll find no water."

The two lads had not gone fifty yards ere they came across a small stream. Andy bent down, and raising some of the water in the palm of his hand applied it to his lips.

"Fresh as one could wish," he pronounced.
