When I awoke, after a length of time which I could not reckon, the "Terror" had not yet returned to the surface of the sea.
This maneuver was executed a little later.

The daylight pierced my porthole; and at the same moment I felt the pitching and tossing to which we were subjected by a heavy sea.
I was allowed to take my place once more outside the hatchway; where my first thought was for the weather.

A storm was approaching from the northwest.

Vivid lightning darted amid the dense, black clouds.
Already we could hear the rumbling of thunder echoing continuously through space.

I was surprised--more than surprised, frightened!--by the rapidity with which the storm rushed upward toward the zenith.
Scarcely would a ship have had time to furl her sails to escape the shock of the blast, before it was upon her! The advance was as swift as it was terrible.
Suddenly the wind was unchained with unheard of violence, as if it had suddenly burst from this prison of cloud.
