“I never thought of that,” he said, and he felt as if a cold chill was running through him, to give place to a hot feverish sensation, accompanied by thirst.

Then he recovered his boyish elasticity.

“Here,” he cried, “never say die! I’m not going to give up like this. Look here; we’ve got a spring at home where the water trickles out of a crack in the rock and flows down into a great stone tank like a well. It only comes in drops, but it’s always dropping, and so we have enough for our wants.”

“Pity you didn’t bring your tank here,” said the middy. “What’s the good of telling me that?”

“Because the cliff all along here for miles has places where the water trickles out, and I shouldn’t be a bit surprised if we were to find that the smugglers have something in the shape of a tank here in this place. They must have wanted water here, and they would be sure to have saved any that trickled in.”

“Then you’d better find it,” said the middy.

“Come along, then; let’s search. This place is very big.”

“You can if you like. I’ve had such a dose this morning, just when I felt I was going to get out, that I’m going to lie down and try to forget it.”

“What! Go to sleep?” cried Aleck.

“Yes.”
