I often asked Peterkin to explain what he meant by "ticket," but he always answered me by going into fits of laughter.

However, by observing the occasions on which he used it, I came to understand that it meant to show that something was remarkably good, or fortunate.
On coming up we found that Peterkin was vainly endeavouring to pull the axe out of the oar, into which, it will be remembered, Jack struck it while endeavouring to cut away the cordage among which it had become entangled at the bow of the ship.

"Ah! that is capital indeed," cried Jack, at the same time giving the axe a wrench that plucked it out of the tough wood.

"How fortunate this is! It will be of more value to us than a hundred knives, and the edge is quite new and sharp." "I'll answer for the toughness of the handle at any rate," cried Peterkin; "my arms are nearly pulled out of the sockets.
