The sledge, slowly propelled by its wheel, went up the face of the rock as if it had been a fly climbing up a pane of glass, and Gallinet, suspended below this sledge by a strap under his arms, was hauled to the top of the precipice.
It was not necessary to climb any such precipices in ascending an iceberg, but there were some steep slopes, and up these the party were safely carried, one by one, by what they called their Fly-foot Sledge.
After an hour or two of climbing, our party safely reached the topmost point of the iceberg, and began to gaze about them.

They soon found that beyond them there were other peaks and pinnacles, and that it would have been difficult to make a circuit which would enable them to continue Mr.Marcy's plan of a canal along the level ice.

Far beyond them, to the south, ice hills and ice mountains were scattered here and there.
Suddenly Mr.Gibbs gave a shout of surprise.
"I have been here before," said he.
"Of course you have," replied Mr.Marcy.

"This is Lake Shiver.

Don't you see, away over there on the other side of the open water below us, that little dark spot in the icy wall?
That is the frozen polar bear.
