tening to crush the ship between
the two. Just then a low berg came driving up from the southward,
dashing the spray over its sides, and with its forehead ploughing up
the smaller ice as if in scorn. A happy thought flashed across the
captain's mind.

"Down the quarter boat," he cried.

In an instant it struck the water, and four men were on the thwarts.

"Cast an ice-anchor on that berg."

Peter Grim obeyed the order, and, with a swing that Hercules would have
envied, planted it securely. In another moment the ship was following in
the wake of this novel tug! It was a moment of great danger, for the
bergs encroached on their narrow canal as they advanced, obliging them
to brace the yards to clear the impending ice-walls, and they shaved the
large berg so closely that the port quarter-boat would have been crushed
if it had not been taken from the davits. Five minutes of such
travelling brought them abreast of a grounded berg, to which they
resolved to make fast. The order was given to cast off the rope. Away
went their white tug on his race to the far north, and the ship swung
round in safety under the lee of the berg, where the crew acknowledged
with gratitude their merciful deliverance from imminent danger.

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 b
