"Well; out with it."
"I should like to call it Gretchen. Port Gretchen will sound very well on our future map."
"Well, then, Port Gretchen let it be," said the Professor. And thus it was that the memory of my dear girl was attached to our adventurous and memorable expedition.
When we left the shore the wind was blowing from the northward and eastward. We went directly before the wind at a much greater speed than might have been expected from a raft. The dense layers of atmosphere at that depth had great propelling power and acted upon the sail with considerable force. At the end of an hour, my uncle, who had been taking careful observations, was enabled to judge of the rapidity with which we moved. It was far beyond anything seen in the upper world.
"If," he said, "we continue to advance at our present rate, we shall have traveled at least thirty leagues in twenty-four hours. With a mere raft this is an almost incredible velocity."
I certainly was surprised, and without making any reply went forward upon the raft. Already the northern shore was fading away on the edge of the horizon. The two shores appeared to separate more and more, leaving a wide and open space for our departure. Before me I could see nothing but the vast and apparently limitless sea—upon which we floated—the only living objects in sight.
Huge and dark clouds cast their gray shadows below—shadows which seemed to crush that colorless and sullen water by their weight. Anything more suggestive of gloom and of regions of nether darkness I never beheld.

Presently we were wholly out of sight of land, not a vestige could be seen, nor any indication of where we were going. So still and motionless did we seem without any distant point to fix our eyes on, that but for the phosphoric light at the wake of the raft I should have fancied that we were still and motionless.
But I knew that we were advancing at a very rapid rate.
About twelve o'clock in the day, vast collections of sea-
