“They have seen us,” said Morgan excitedly.

“No,” said Captain Strong, “we were in the shadow. Now, then, three on each side. I’ll lead. Slowly does it. Mark, my boy, go to the stern; you may keep it from touching the rock. Every pound of help will be worth something now.”

Mark eagerly went as directed, and the next minute, with three strong men on either side, the gig was lifted up, and borne softly forward almost without a sound, the party listening intently to the loud jabbering going on aboard the praus.

The task was fairly easy at first, for it was for some distance over the nearly level sand that the gig was carried, but soon rocks began to crop up in their path, and in spite of the care exercised the keel of the boat suddenly grated loudly upon a projecting piece of stone; an effort was made to slew her round slightly to avoid it, and this caused Mr Gregory to catch his foot on another block of stone, and nearly fall.

The captain uttered a loud “Hist!” and all stood fast, with beating hearts, for a loud voice spoke in Malay, and the jabbering on board the boats ceased, as if all were listening to try and make out what the unusual noise was ashore.

Just at this moment there was another vivid flash from the mountain, and the praus could be plainly seen, while now the little party by the boat realised how thoroughly they were in the shadow of the black rocks.

“If there is a blaze like that when we are on the top of the ridge,” whispered the captain, “we shall be seen.”

Not another word was spoken, and for quite a quarter of an hour there was an ominous silence as they all waited for the talking to begin again on board the vessels.

But there was not a sound, and it was evident that the crews were listening, when suddenly Morgan laid his hand upon the captain’s arm, and pointed in the direction of the lagoon about half-way between them and the praus.

Every one grasped the meaning, and a chill of dread ran through Mark, in whose mind’s eye wavy krisses were flashed and razor-edged spears darted, for there, plainly enough, as shown by the flashing and undulating of the luminous creatures of the water, which they knew so well, two men were swimming ashore, to see what was the cause of the noise.
