“Of course we did, the divvil doubt it, sir,” answered the second mate in his usual Irish fashion. “Thin, sor, we ran for five hours from that p’int on a west by south course, going between ten and twelve knots; for, though I didn’t say it meself, Mister Fosset tould me the wind was freshinin’ all the toime, so that we must have travelled about sixty miles, more or less.”

“So that brings us to this blue mark here?”

“Yes, sor, to 42° 28 minutes north, and 51° 12 minutes west.”

“Then we sailed right before the wind, due south?”

“Sure, an’ we did that same afther Mister Haldane’s will-o’-the-wisp for three hours, bedad!”

“Oh, Mr O’Neil,” I pleaded, “please leave me out of it. I’m sure I’ve seen and heard enough of the ship already!”

“Be aisy, me darlint! It’s only me fun, sure; and I mean ye no harrum,” said he in his jocular way. “Arrah how can I lave ye out of the story when ye’re the howl h’id and tail of it, sure, and without ye there’d be none to tile. Yes, cap’en, dear, sure, an’ as I was a-saying when Haldane broke in upon me yarn, thray hours on this southerly course brought us here right where ye see me little finger, now!”

“About 51° 5 minutes west longitude and 41° 40 minutes north latitude. How did you get this, eh?”

“Faith, sor, the ould moon looked so moighty plisint that night that I took a lunar or two, jist to divart mesilf with, when Spokeshave wint below and there was nobody lift to poke fun at, sure!”

“A very useful sort of amusement,” said the skipper drily. “And I see, too, you’ve put in the distance we’ve run, by dead reckoning, as about another fifty miles or so?”
