ON the thirteenth of August we were up betimes.There was no time to be lost.We now had to inaugurate a new kind of locomotion,which would have the advantage of being rapid and not fatiguing.
A mast,made of two pieces of wood fastened together,to give additional strength,a yard made from another one,the sail a linen sheet from our bed.We were fortunately in no want of cordage,and the whole on trial appeared solid and seaworthy.
At six o'clock in the morning,when the eager and enthusiastic Professor gave the signal to embark,the victuals,the luggage,all our instruments,our weapons,and a goodly supply of sweet water,which we had collected from springs in the rocks,were placed on the raft.
Hans had,with considerable ingenuity,contrived a rudder,which enabled him to guide the floating apparatus with ease.He took the tiller,as a matter of course.The worthy man was as good a sailor as he was a guide and duck hunter.I then let go the painter which held us to the shore,the sail was brought to the wind,and we made a rapid offing.
Our sea voyage had at length commenced;and once more we were making for distant and unknown regions.
Just as we were about to leave the little port where the raft had been constructed,my uncle,who was very strong as to geographic nomenclature,wanted to give it a name,and among others,suggested mine.
"Well,"said I,"before you decide I have another to propose.""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 Icould 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 grey 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.Silvery rays of electric light,reflected here and there upon some small spots of water,brought up luminous sparkles in the long wake of our cumbrous bark.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 seaweed were discovered surrounding us on all sides.I was aware of the extraordinary vegetative power of these plants,which have been known to creep along the bottom of the great ocean,and stop the advance of large ships.But never were seaweeds ever seen,so gigantic and wonderful as those of the Central Sea.I could well imagine how,seen at a distance,tossing and heaving on the summit of the billows,the long lines of algae have been taken for living things,and thus have been fertile sources of the belief in sea serpents.
Our raft swept past great specimens of fucus or seawrack,from three to four thousand feet in length,immense,incredibly long,looking like snakes that stretched out far beyond our horizon.It afforded me great amusement to gaze on their variegated ribbon-like endless lengths.Hour after hour passed without our coming to the termination of these floating weeds.If my astonishment increased,my patience was well-nigh exhausted.
What natural force could possibly have produced such abnormal and extraordinary plants?What must have been the aspect of the globe,during the first centuries of its formation,when under the combined action of heat and humidity,the vegetable kingdom occupied its vast surface to the exclusion of everything else?
These were considerations of never-ending interest for the geologist and the philosopher.
All this while we were advancing on our journey;and at length night came;but as I had remarked the evening before,the luminous state of the atmosphere was in nothing diminished.Whatever was the cause,it was a phenomenon upon the duration of which we could calculate with certainty.
As soon as our supper had been disposed of,and some little speculative conversation indulged in,I stretched myself at the foot of the mast,and presently went to sleep.
Hans remained motionless at the tiller,allowing the raft to rise and fall on the waves.The wind being aft,and the sail square,all he had to do was to keep his oar in the center.
Ever since we had taken our departure from the newly named Port Gretchen,my worthy uncle had directed me to keep a regular log of our day's navigation,with instructions to put down even the most minute particulars,every interesting and curious phenomenon,the direction of the wind,our rate of sailing,the distance we went;in a word,every incident of our extraordinary voyage.
From our log,therefore,I tell the story of our voyage on the Central Sea.
