But summer and autumn and the first months of winter wore away, and, after spending a whole fortnight at the white hare-shooting among the mountains of Perthshire—and harder work I defy you to find—Frank was at last declared thoroughly broken in, completely hardened off.

“A man,” said Chisholm, “that can stand a week or two among white hares, and not feel too tired to sleep at night, is fit for anything. Now, boys,” he added, “what do you say to a run right away up to the polar ice-fields?”

“I’m in,” said Fred quietly.

“Oh!” said Chisholm, “you’re always in for anything. If I asked you to take a trip to the moon you’d jump at it.”

“Or over it,” said Fred, smiling, “like the cow in the poem of ‘Hey, diddle diddle;’ but are you in earnest about the ice-fields?”

“Downright.”

“Well,” said Frank, with assumed modesty, “if you think I’m ‘broke’ enough, please I’d like to go too.”

“Bravo!” cried Chisholm O’Grahame, “that settles the question.”
