I do not think it necessary to even consider the contingency of the greatest iceberg or floe reaching the bottom of the arctic waters; consequently, without trouble or danger, the Dipsey can make a straight course for the extreme north.
"By means of the instruments the Dipsey will carry it will be comparatively easy to determine the position of the pole, and before this point is reached I believe she will find herself in an open sea, where she may rise to the surface.

But if this should not be the case, a comparatively thin place in the ice will be chosen, and a great opening blown through it by means of an ascensional shell, several of which she will carry.

She will then rise to the surface of the water in this opening, and the necessary operations will be carried on." "Mr.Clewe," said Margaret Raleigh, "the thing is so terrible I cannot bear to think of it.

The Dipsey may have to sail hundreds and hundreds of miles under the ice, shut in as if an awful lid were put over her.

No matter what happened down there, she could not come up and get out; it would be the same thing as having a vast sky of ice stretched out above one.
