“You’ve not forgotten how to make lobscouse or plum-duff, I dare say?”

Bob’s eyes brightened as he replied stoutly, “By no manner o’ means.”

“Then be off, and, remember, sharp six.”

“Ay, ay, sir,” cried the old seaman in a nautical tone that he had not used for many years, and the very sound of which stirred his heart with old memories. He was about to retire, but paused at the threshold of the green door.

“Beg parding, sir, but if I might make so bold as to ax—”

“Go on, Bob,” said Fred encouragingly.

“I heerd ye say to our cashier, sir, that you wos goin’ for to chase the sun. Wot sort of a chase may that be, sir?”

“Ha! Bowie, that’s a curious chase, but not a wild goose one, as I hope to show you in a month or two. You know, of course, that in the regions of the earth north of the Arctic Circle the sun shines by night as well as by day for several weeks in summer?”

“In coorse I do,” answered Bob; “every seaman knows that or ought for to know it; and that it’s dark all day as well as all night in winter for some weeks, just to make up for it, so to speak.”

“Well, Bob, I am very desirous to see this wonderful sight with my own eyes, but I fear I am almost too late of setting out. The season is so far advanced that the sun is setting farther and farther north every night, and if the winds baffle us I won’t be able to catch him sitting up all night; but if the winds serve, and we have plenty of them we may yet be in time to see him draw an unbroken circle in the sky. You see it will be a regular chase, for the sun travels north at a rapid pace. D’you understand?”
