look of self-satisfied placidity.

"Look out, Meetuck--pull up!" cried Fred in some alarm; but the Esquimau
paid no attention.

"O morther! we're gone now for iver," exclaimed O'Riley, shutting his
eyes and clenching his teeth as he laid fast hold of the sides of the
sledge.

The feet of the dogs went faster and faster until they pattered on the
hard surface of the snow like rain. Round came the long whip, as O'Riley
said, "like the shot of a young cannon," and the next moment they were
across, skimming over the ice on the other side like the wind.

It happened that there had been a break in the ice at this point on the
previous night, and the floes had been cemented by a sheet of ice only
an inch thick. Upon this, to the consternation even of Meetuck himself,
they now passed, and in a moment, ere they were aware, they were passing
over a smooth, black surface that undulated beneath them like the waves
of the sea, and crackled fearfully. There was nothing for it but to go
on. A moment's halt would have allowed the sledge to break through, and
leave them struggling in the water. There was no time for remark. Each
man held his breath. Meetuck sent the heavy lash with a tremendous crack
over the backs of the whole team; but just as they neared the solid floe
the left runner broke through. In a moment the men flung themselves
horizontally upon their breasts, and scrambled over the smooth surface
until they gained the white ice, while the sledge and the dogs nearest
to it were sinking. One vigorous pull, however, by dogs and men
together, dragged the sledge upon the solid floe, even before the things
in it had got wet.
