"See," said Tammy. "It's just like the shadow of a ship!"

And it was. The shadow of a ship rising out of the unexplored immensity beneath our keel. Plummer, who had not yet gone forrard, caught Tammy's last remark, and glanced over.

"What's 'e mean?" he asked.

"That!" replied Tammy, and pointed.

I jabbed my elbow into his ribs; but it was too late. Plummer had seen.
Curiously enough, though, he seemed to think nothing of it.

"That ain't nothin', 'cept ther shadder er ther ship," he said.

Tammy, after my hint, let it go at that. But when Plummer had gone forrard with the others, I told him not to go telling everything round the decks, like that.

"We've got to be thundering careful!" I remarked. "You know what the Old
Man said, last watch!"

"Yes," said Tammy. "I wasn't thinking; I'll be careful next time."

A little way from me the Second Mate was still staring down into the water. I turned, and spoke to him.
