"'e's singin' out for some one to go aft an' relieve ther wheel," said Quoin, who had gone to the door to listen. "Yer'd better 'urry up, Plummer."

"What's ther time?" asked Plummer, standing up and knocking out his pipe. "Must be close on ter four bells, 'oo's next wheel is it?"

"It's all right, Plummer," I said, getting up from the chest on which I had been sitting. "I'll go along. It's my wheel, and it only wants a couple of minutes to four bells."

Plummer sat down again, and I went out of the fo'cas'le. Reaching the poop, I met Tammy on the lee side, pacing up and down.

"Who's at the wheel?" I asked him, in astonishment.

"The Second Mate," he said, in a shaky sort of voice. "He's waiting to be relieved. I'll tell you all about it as soon as I get a chance."

I went on aft to the wheel.

"Who's that?" the Second inquired.

"It's Jessop, Sir," I answered.

He gave me the course, and then, without another word, went forrard along the poop. On the break, I heard him call Tammy's name, and then for some minutes he was talking to him; though what he was saying, I could not possibly hear. For my part, I was tremendously curious to know why the Second Mate had taken the wheel. I knew that if it were just a matter of bad steering on Tammy's part, he would not have dreamt of doing such a thing. There had been something queer happening, about which I had yet to learn; of this, I felt sure.
