The steaks we had that night, and they were fine; and the following morning we tasted the broth. It seemed odd to be eating a creature that should, by all the laws of paleontology, have been extinct for several million years. It gave one a feeling of newness that was almost embarrassing, although it didn't seem to embarrass our appetites. Olson ate until Ithought he would burst.
The girl ate with us that night at the little officers' mess just back of the torpedo compartment. The narrow table was unfolded;the four stools were set out; and for the first time in days we sat down to eat, and for the first time in weeks we had something to eat other than the monotony of the short rations of an impoverished U-boat. Nobs sat between the girl and me and was fed with morsels of the Plesiosaurus steak, at the risk of forever contaminating his manners. He looked at me sheepishly all the time, for he knew that no well-bred dog should eat at table; but the poor fellow was so wasted from improper food that I couldn't enjoy my own meal had he been denied an immediate share in it; and anyway Lys wanted to feed him. So there you are.
Lys was coldly polite to me and sweetly gracious to Bradley and Olson. She wasn't of the gushing type, I knew; so I didn't expect much from her and was duly grateful for the few morsels of attention she threw upon the floor to me. We had a pleasant meal, with only one unfortunate occurrence--when Olson suggested that possibly the creature we were eating was the same one that ate the German. It was some time before we could persuade the girl to continue her meal, but at last Bradley prevailed upon her, pointing out that we had come upstream nearly forty miles since the boche had been seized, and that during that time we had seen literally thousands of these denizens of the river, indicating that the chances were very remote that this was the same Plesiosaur. "And anyway," he concluded, "it was only a scheme of Mr. Olson's to get all the steaks for himself."We discussed the future and ventured opinions as to what lay before us; but we could only theorize at best, for none of us knew. If the whole land was infested by these and similar horrid monsters, life would be impossible upon it, and we decided that we would only search long enough to find and take aboard fresh water and such meat and fruits as might be safely procurable and then retrace our way beneath the cliffs to the open sea.
And so at last we turned into our narrow bunks, hopeful, happy and at peace with ourselves, our lives and our God, to awaken the following morning refreshed and still optimistic. We had an easy time getting away--as we learned later, because the saurians do not commence to feed until late in the morning. From noon to midnight their curve of activity is at its height, while from dawn to about nine o'clock it is lowest. As a matter of fact, we didn't see one of them all the time we were getting under way, though I had the cannon raised to the deck and manned against an assault. I hoped, but I was none too sure, that shells might discourage them. The trees were full of monkeys of all sizes and shades, and once we thought we saw a manlike creature watching us from the depth of the forest.
Shortly after we resumed our course upstream, we saw the mouth of another and smaller river emptying into the main channel from the south--that is, upon our right; and almost immediately after we came upon a large island five or six miles in length; and at fifty miles there was a still larger river than the last coming in from the northwest, the course of the main stream having now changed to northeast by southwest. The water was quite free from reptiles, and the vegetation upon the banks of the river had altered to more open and parklike forest, with eucalyptus and acacia mingled with a scattering of tree ferns, as though two distinct periods of geologic time had overlapped and merged.
The grass, too, was less flowering, though there were still gorgeous patches mottling the greensward; and lastly, the fauna was less multitudinous.
Six or seven miles farther, and the river widened considerably;before us opened an expanse of water to the farther horizon, and then we sailed out upon an inland sea so large that only a shore-line upon our side was visible to us. The waters all about us were alive with life. There were still a few reptiles; but there were fish by the thousands, by the millions.
The water of the inland sea was very warm, almost hot, and the atmosphere was hot and heavy above it. It seemed strange that beyond the buttressed walls of Caprona icebergs floated and the south wind was biting, for only a gentle breeze moved across the face of these living waters, and that was damp and warm.
Gradually, we commenced to divest ourselves of our clothing, retaining only sufficient for modesty; but the sun was not hot.
It was more the heat of a steam-room than of an oven.
We coasted up the shore of the lake in a north-westerly direction, sounding all the time. We found the lake deep and the bottom rocky and steeply shelving toward the center, and once when Imoved straight out from shore to take other soundings we could find no bottom whatsoever. In open spaces along the shore we caught occasional glimpses of the distant cliffs, and here they appeared only a trifle less precipitous than those which bound Caprona on the seaward side. My theory is that in a far distant era Caprona was a mighty mountain--perhaps the world's mightiest volcanic action blew off the entire crest, blew thousands of feet of the mountain upward and outward and onto the surrounding continent, leaving a great crater; and then, possibly, the continent sank as ancient continents have been known to do, leaving only the summit of Caprona above the sea.
The encircling walls, the central lake, the hot springs which feed the lake, all point to a conclusion, and the fauna and the flora bear indisputable evidence that Caprona was once part of some great land-mass.
