And so the top-mast was passed, and with the main topgallant mast they came to the ice-covered cross-spells, which had been lashed on, and directly after Steve was beneath the cask raising his hand to push open the hinged bottom; but, to his surprise, it did not yield.

“It’s frozen!” he cried; and he made effort after effort to move the trap, but in vain.

“You’ll have to let me come, sir,” said Johannes quietly. “I’m thinking that the nest is full of snow.”

Steve moved off the spell on which he stood, and held on to the shrouds upon the other side, leaving room for the Norseman to take his place.

“Well?” said Steve, as the man exerted his huge strength without effect.

“More than I can do, sir,” said Johannes quietly. “Let’s try it a little at a time.” And, taking tightly hold, he began to thrust with one shoulder up and up, until the trap began to crack and give way little by little.

Then a little powdery snow began to crumble out, and the Norseman paused to rest.

“You see I am useful,” he said, smiling. “I don’t think you could have moved that.”

“Aloft there! Can’t you get in?” came from below.

“Crow’s-nest full of ice and snow!” cried Steve.
