The surface of this ice-belt was covered with immense masses of rock many tons in weight, which had fallen from the cliffs above.

Pointing to one of these as they drove along, West remarked to Fred,-- "There is a mystery explained, sir.

I have often wondered how huge, solitary stones, that no machinery of man's making could lift, have come to be placed on sandy shores where there were no other rocks of any kind within many miles of them.

The ice must have done it, I see." "True, West.

The ice, if it could speak, would explain many things that now seem to us mysterious; and yonder goes a big rock on a journey that may perhaps terminate at a thousand miles to the south of this." The rock referred to was a large mass that became detached from the cliffs and fell, as he spoke, with a tremendous crash upon the ice-belt, along which it rolled for fifty yards.
