A mast was made of two poles spliced together, a yard was made of a third, a blanket borrowed from our coverings made a tolerable sail. There was no want of cordage for the rigging, and everything was well and firmly made. The provisions, the baggage, the instruments, the guns, and a good quantity of fresh water from the rocks around, all found their proper places on board; and at six the Professor gave the signal to embark. Hans had fitted up a rudder to steer his vessel. He took the tiller, and unmoored; the sail was set, and we were soon afloat. At the moment of leaving the harbour, my uncle, who was tenaciously fond of naming his new discoveries, wanted to give it a name, and proposed mine amongst others. "But I have a better to propose," I said: "Gräuben. Let it be called Port Gräuben; it will look very well upon the map." "Port Gräuben let it be then." And so the cherished remembrance of my Virlandaise became associated with our adventurous expedition. The wind was from the north-west. We went with it at a high rate of speed. The dense atmosphere acted with great force and impelled us swiftly on. In an hour my uncle had been able to estimate our progress. At this rate, he said, we shall make thirty leagues in twenty-four hours, and we shall soon come in sight of the opposite shore. I made no answer, but went and sat forward. The northern shore was already beginning to dip under the horizon. The eastern and western strands spread wide as if to bid us farewell. Before our eyes lay far and wide a vast sea; shadows of great clouds swept heavily over its silver-grey surface; the glistening bluish rays of electric light, here and there reflected by the dancing drops of spray, shot out little sheaves of light from the track we left in our rear. Soon we entirely lost sight of land; no object was left for the eye to judge by, and but for the frothy track of the raft, I might have thought we were standing still. About twelve, immense shoals of seaweeds came in sight. I was aware of the great powers of vegetation that characterise these plants, which grow at a depth of twelve thousand feet, reproduce themselves under a pressure of four hundred atmospheres, and sometimes form barriers strong enough to impede the course of a ship. But never, I think, were such seaweeds as those which we saw floating in immense waving lines upon the sea of Liedenbrock. Our raft skirted the whole length of the fuci, three or four thousand feet long, undulating like vast serpents beyond the reach of sight; I found some amusement in tracing these endless waves, always thinking I should come to the end of them, and for hours my patience was vying with my surprise. What natural force could have produced such plants, and what must have been the appearance of the earth in the first ages of its formation, when, under the action of heat and moisture, the vegetable kingdom alone was developing on its surface?
