When he came aboard, his sisters met him with pleasure, although with tears in their eyes, for he had run a great risk.
A day or two after this, when still farther north, the children had had their first run upon the ice.

It was all so strange, and the ice was so white, that they felt very giddy for a time.

But the professor held Pansy, and Tom walked by Aralia.
The whole ice-pack seemed one vast plain, like a bleak moorland in winter, only with little hillocks of ice here and there called hummocks, for the flat pieces of ice were all frozen hard together, and Ara wondered where "Greenland's icy mountains" had all got to.
There were no bears about to-day, and no seals, only the sea-birds that went wheeling and screaming about them in thousands.

When they got back to the ship it was dinner-time, and both were snow-blind.

Although the ship was now kept well away from the ice-pack, they could often see vessels far in through frozen ice, but busy, busy at their terrible work.
