Up he went over a wall of ice, and the horizon burst upon his view.
But he was amazed at his position.
He was far up on the top of the mighty berg.
As far as he could see all was a vast berg-studded sea.
An immense platform of ice extended far to the northern end of the berg.
Barney fancied that he might see the submarine boat from this position.
But though he leaned far over the ice cliffs and closely scrutinized the line, he could see no sign of the Explorer.
It was not in sight.
But Barney reflected that it might be upon the other side of the berg, and at once started thither.
But he found that it was quite impossible for him to reach there.
