My uncle took soundings several times. He tied the heaviest of our pickaxes to a long rope which he let down two hundred fathoms. No bottom yet; and we had some difficulty in hauling up our plummet. But when the pick was shipped again, Hans pointed out on its surface deep prints as if it had been violently compressed between two hard bodies. I looked at the hunter. "_Tänder,_" said he. I could not understand him, and turned to my uncle who was entirely absorbed in his calculations. I had rather not disturb him while he is quiet. I return to the Icelander. He by a snapping motion of his jaws conveys his ideas to me. "Teeth!" I cried, considering the iron bar with more attention. Yes, indeed, those are the marks of teeth imprinted upon the metal! The jaws which they arm must be possessed of amazing strength. Is there some monster beneath us belonging to the extinct races, more voracious than the shark, more fearful in vastness than the whale? I could not take my eyes off this indented iron bar. Surely will my last night's dream be realised? These thoughts agitated me all day, and my imagination scarcely calmed down after several hours' sleep. _Monday, August 17.--_ I am trying to recall the peculiar instincts of the monsters of the pre-adamite world, who, coming next in succession after the molluscs, the crustaceans and the fishes, preceded the animals of mammalian race upon the earth. The world then belonged to reptiles. Those monsters held the mastery in the seas of the secondary period. They possessed a perfect organisation, gigantic proportions, prodigious strength. The saurians of our day, the alligators and the crocodiles, are but feeble reproductions of their forefathers of primitive ages. I shudder as I recall these monsters to my remembrance. No human eye has ever beheld them living. They burdened this earth a thousand ages before man appeared, but their fossil remains, found in the argillaceous limestone called by the English the lias, have enabled their colossal structure to be perfectly built up again and anatomically ascertained. I saw at the Hamburg museum the skeleton of one of these creatures thirty feet in length. Am I then fated--I, a denizen of earth--to be placed face to face with these representatives of long extinct families? No; surely it cannot be! Yet the deep marks of conical teeth upon the iron pick are certainly those of the crocodile. My eyes are fearfully bent upon the sea. I dread to see one of these monsters darting forth from its submarine caverns. I suppose Professor Liedenbrock was of my opinion too, and even shared my fears, for after having examined the pick, his eyes traversed the ocean from side to side. What a very bad notion that was of his, I thought to myself, to take soundings just here! He has disturbed some monstrous beast in its remote den, and if we are not attacked on our voyage-- I look at our guns and see that they are all right. My uncle notices it, and looks on approvingly.
