Saturday, August 15th. The sea still retains its uniform monotony. The same leaden hue, the same eternal glare from above. No indication of land being in sight. The horizon appears to retreat before us, more and more as we advance.  
My head, still dull and heavy from the effects of my extraordinary dream, which I cannot as yet banish from my mind.
 
The Professor, who has not dreamed, is, however, in one of his morose and unaccountable humors. Spends his time in scanning the horizon, at every point of the compass. His telescope is raised every moment to his eyes, and when he finds nothing to give any clue to our whereabouts, he assumes a Napoleonic attitude and walks anxiously.
 
I remarked that my uncle, the Professor, had a strong tendency to resume his old impatient character, and I could not but make a note of this disagreeable circumstance in my journal. I saw clearly that it had required all the influence of my danger and suffering, to extract from him one scintillation of humane feeling. Now that I was quite recovered, his original nature had conquered and obtained the upper hand.
 
And, after all, what had he to be angry and annoyed about, now more than at any other time? Was not the journey being accomplished under the most favorable circumstances? Was not the raft progressing with the most marvelous rapidity?
 
What, then, could be the matter? After one or two preliminary hems, I determined to inquire.
 
"You seem uneasy, Uncle," said I, when for about the hundredth time he put down his telescope and walked up and down, muttering to himself.
 
"No, I am not uneasy," he replied in a dry harsh tone, "by no means."
 
"Perhaps I should have said impatient," I replied, softening the force of my remark.
 
"Enough to make me so, I think."
 
"And yet we are advancing at a rate seldom attained by a raft," I remarked.
 
"What matters that?" cried my uncle. "I am not vexed at the rate we go at, but I am annoyed to find the sea so much vaster than I expected."
 
I then recollected that the Professor, before our departure, had estimated the length of this subterranean ocean as at most about thirty leagues. Now we had traveled at least over thrice that distance without discovering any trace of the distant shore. I began to understand my uncle's anger.
 
"We are not going down," suddenly exclaimed the Professor. "We are not progressing with our great discoveries. All this is utter loss of time. After all, I did not come from home to undertake a party of pleasure. This voyage on a raft over a pond annoys and wearies me."
 
He called this adventurous journey a party of pleasure, and this great inland sea a pond!
 
"But," argued I, "if we have followed the route indicated by the great Saknussemm, we cannot be going far wrong."
 
"'That is the question,' as the great, the immortal Shakespeare, has it. Are we following the route indicated by that wondrous sage? Did Saknussemm ever fall in with this great sheet of water? If he did, did he cross it? I begin to fear that the rivulet we adopted for a guide has led us wrong."
 
"In any case, we can never regret having come thus far. It is worth the whole journey to have enjoyed this magnificent spectacle—it is something to have seen."
 
"I care nothing about seeing, nor about magnificent spectacles. I came down into the interior of the earth with an object, and that object I mean to attain. Don't talk to me about admiring scenery, or any other sentimental trash."
 
After this I thought it well to hold my tongue, and allow the Professor to bite his lips until the blood came, without further remark.
 
At six o'clock in the evening, our matter-of-fact guide, Hans, asked for his week's salary, and receiving his three rix-dollars, put them carefully in his pocket. He was perfectly contented and satisfied.
 
Sunday, August 16th. Nothing new to record. The same weather as before. The wind has a slight tendency to freshen up, with signs of an approaching gale. When I awoke, my first observation was in regard to the intensity of the light. I keep on fearing, day after day, that the extraordinary electric phenomenon should become first obscured, and then go wholly out, leaving us in total darkness. Nothing, however, of the kind occurs. The shadow of the raft, its mast and sails, is clearly distinguished on the surface of the water.
 
This wondrous sea is, after all, infinite in its extent. It must be quite as wide as the Mediterranean—or perhaps even as the great Atlantic Ocean. Why, after all, should it not be so?
 
My uncle has on more than one occasion, tried deep-sea soundings. He tied the cross of one of our heaviest crowbars to the extremity of a cord, which he allowed to run out to the extent of two hundred fathoms. We had the greatest difficulty in hoisting in our novel kind of lead.
 
When the crowbar was finally dragged on board, Hans called my attention to some singular marks upon its surface. The piece of iron looked as if it had been crushed between two very hard substances.
 
I looked at our worthy guide with an inquiring glance.
 
"Tander," said he.
 
Of course I was at a loss to understand. I turned round towards my uncle, absorbed in gloomy reflections. I had little wish to disturb him from his reverie. I accordingly turned once more towards our worthy Icelander.
 
Hans very quietly and significantly opened his mouth once or twice, as if in the act of biting, and in this way made me understand his meaning.
 
"Teeth!" cried I, with stupefaction, as I examined the bar of iron with more attention.
 
Yes. There can be no doubt about the matter. The indentations on the bar of iron are the marks of teeth! What jaws must the owner of such molars be possessed of! Have we then, come upon a monster of unknown species, which still exists within the vast waste of waters—a monster more voracious than a shark, more terrible and bulky than the whale? I am unable to withdraw my eyes from the bar of iron, actually half crushed!
 
Is, then, my dream about to come true—a dread and terrible reality?
 
All day my thoughts were bent upon these speculations, and my imagination scarcely regained a degree of calmness and power of reflection until after a sleep of many hours.
 
This day, as on other Sundays, we observed as a day of rest and pious meditation.
 
Monday, August 17th. I have been trying to realize from memory the particular instincts of those antediluvian animals of the secondary period, which succeeding to the mollusca, to the crustacea, and to the fish, preceded the appearance of the race of mammifers. The generation of reptiles then reigned supreme upon the earth. These hideous monsters ruled everything in the seas of the secondary period, which formed the strata of which the Jura mountains are composed. Nature had endowed them with perfect organization. What a gigantic structure was theirs; what vast and prodigious strength they possessed!
 
The existing saurians, which include all such reptiles as lizards, crocodiles, and alligators, even the largest and most formidable of their class, are but feeble imitations of their mighty sires, the animals of ages long ago. If there were giants in the days of old, there were also gigantic animals.
 
I shuddered as I evolved from my mind the idea and recollection of these awful monsters. No eye of man had seen them in the flesh. They took their walks abroad upon the face of the earth thousands of ages before man came into existence, and their fossil bones, discovered in the limestone, have allowed us to reconstruct them anatomically, and thus to get some faint idea of their colossal formation.
 
I recollect once seeing in the great Museum of Hamburg the skeleton of one of these wonderful saurians. It measured no less than thirty feet from the nose to the tail. Am I, then, an inhabitant of the earth of the present day, destined to find myself face to face with a representative of this antediluvian family? I can scarcely believe it possible; I can hardly believe it true. And yet these marks of powerful teeth upon the bar of iron! Can there be a doubt from their shape that the bite is the bite of a crocodile?
 
My eyes stare wildly and with terror upon the subterranean sea. Every moment I expect one of these monsters to rise from its vast cavernous depths.
 
I fancy that the worthy Professor in some measure shares my notions, if not my fears, for, after an attentive examination of the crowbar, he cast his eyes rapidly over the mighty and mysterious ocean.
 
"What could possess him to leave the land," I thought, "as if the depth of this water was of any importance to us. ............
