“That is right,” agreed Clifford. “We must go and look for him.”

With which they got upon their feet and looked about them.

Nothing was to be seen of the Dolphin or her searchlight. All was gloom about them.

But beyond the circle of their helmet lamps Clifford saw a white reef.

“The sunken galleon is on the other side of that,” he said; “the shock of the explosion carried us over here.”

“All roight, sor!” cried Barney, with alacrity.

So they set out for the reef. Below was a sandy plain, and they fancied they could see the excavation over the galleon’s deck.

But when they reached the spot it was not there. Nor was there anything at all familiar in the surroundings.

“Well,” muttered Clifford. “I can’t say that I like this. Let us look on further.”

And this they proceeded to do.
