CHAPTER VII.
_New characters introduced--An old game under novel circumstances--Remarkable appearances in the sky--O'Riley meets with a mishap_.
Dumps was a remarkably grave and sly character, and Poker was a wag--an incorrigible wag--in every sense of the term.

Moreover, although they had an occasional fight, Dumps and Poker were excellent friends, and great favourites with the crew.
We have not yet introduced these individuals to our reader, but as they will act a conspicuous part in the history of the _Dolphin's_ adventurous career in the Arctic Regions, we think it right now to present them.
While at Upernavik, Captain Guy had purchased a team of six good, tough Esquimau dogs, being desirous of taking them to England, and there presenting them to several of his friends who were anxious to possess specimens of those animals.

Two of these dogs stood out conspicuous from their fellows, not only in regard to personal appearance, but also in reference to peculiarities of character.

One was pure white, with a lively expression of countenance, a large shaggy body, two erect, sharp-pointed ears, and a short projection that once had been a tail.
Owing to some cause unknown, however, his tail had been cut or bitten off, and nothing save the stump remained.

But this stump did as much duty as if it had been fifty tails in one.
