As soon as it was daylight we started for the entrance to examine it carefully and find the deepest water. The air was hot and still, and the water of the lagoon had a greasy look.

The first thing that attracted our attention was a large, dark object that rose on the reef where yesterday there had been nearly fifty feet of water. All eyes were directed to it as it lay there like a huge mass of coral weed with great festoons hanging from its sides.

Suddenly the skipper sprang to his feet “My God, it’s a ship!” he cried.

All hands stopped rowing and turned in their seats, when Garnett, who was steering, bawled out to “Give way together!” and we headed straight for it.

As we approached, we saw that it was the hull of a large ship lying on its bilge, but so covered with marine growths that its outline could hardly be traced in the great mass. It lay well out, and the wash of the surf broke against the stern; this is the reason we didn’t notice it during the night. There were three or four feet of water around it, so we forced the boat through the floating weed until we were alongside.

Garnett clambered to the deck amidships closely followed by Frisbow and myself. We made our way aft aloft along the slippery incline by clinging to the weed that covered everything, and reached a large hole that had evidently been the entrance to the cabin. The whole design of the ship was strange and different from any modern vessel I had ever seen. We peered down the opening, but could see nothing inside except various-colored marine growths.

The professor was for going below instantly, but Garnett held back and contented himself with examining the steering-gear, where he was joined by the skipper.

Frisbow let himself down the opening and I, feeling ashamed to let him go alone, let myself down after him.

The cabin was dark inside, for the windows were covered with weed, but I could make out the form of the professor as he groped his way along the slippery floor into the darkness forward.

After going a short distance into what appeared to be a large saloon the grass seemed to grow thinner and I stood up and looked about me. As I did so my head came in sharp contact with a curious brass lamp which hung suspended from one of the deck-beams. My exclamation caused Frisbow to join me, and together we examined the strange fittings about us.
