Having made my observations, I was about to quit the poop, when one of the men called out—

"Tell us what you make it."

"I will when I have worked it out," I replied.

"Work it out here, whilst we looks on."

"Do any of you understand navigation?"

There was no reply.

"Unless you can count," said I, "you'll not be able to follow me."

"Two and two and one makes nine," said a voice.

"What do ye mean by jokin'? You ought to be ashamed o' yourself," exclaimed one of the men. And then there was a blow, and immediately after an oath.

"If you want me to work out these sights in your presence, I'll do so," said I.
