The cargo's there for certain.

You two others," he continued, "draw cutlasses, and keep guard over the prisoners." His orders were obeyed, and the two men stood by guarding Ram, Jemmy, and the cow, who blinked her eyes and smelt at the sea water from time to time, raised her head and uttered a soft low, which was answered from the green top of the cliff two hundred feet above them, where another cow stood gazing down.
The lieutenant and Archy stood up in the boat watching and directing as Dick and his companion searched about in all directions along the lower ledge, and then managed to climb up to the one twenty feet above, where the next minute Dick gave a shout.
"Hah!" cried the lieutenant joyfully.

"He has found them." Ram shut one of his eyes at Jemmy, who made a rumbling noise, but his face did not change.
"What is it, my lad ?" "Cave," cried Dick.
"What's in it ?" "Lobster-pots and old sail.

All wore out." "Nothing else ?" "No, sir." "You go and look." The second man disappeared, but returned directly.
"It's on'y a bit of a hole, sir, and there's nothin' else." The search was continued and ended, for the ledge was shut in by the mighty wall of rock towering above their heads, and the lieutenant was soon convinced that it was impossible for any one to climb that without tackle from above.
"Come back aboard," he said.

"You two stop and guard those prisoners." The sailors stepped back into the boat and resumed their oars, to row steadily east for about half a mile, past several shallow caves, but they could not see one likely to become a hiding-place for smuggled goods, and the rock rose higher and higher above their heads, precluding all ascent.
The boat was rowed quickly back past where the prisoners sat contentedly enough; save the cow, which kept making the great rock wall echo with her lowings, while three more of her kind now stood on high, gazing down at her plight.
The lieutenant now had himself rowed west for about the same distance, but in this direction they did not pass a crack in the great rock wall, let alone a cave, and once more the gig was rowed back.
"Get back into your boat," said the little officer sharply.
"Thank ye, sir," cried Ram.
