As I slowly recalled my collegiate studies and paleontological readings in Bowen's textbooks, I realized that I had looked upon nothing less than a diplodocus of the Upper Jurassic; but how infinitely different was the true, live thing from the crude restorations of Hatcher and Holland! I had had the idea that the diplodocus was a land-animal, but evidently it is partially amphibious. I have seen several since my first encounter, and in each case the creature took to the sea for concealment as soon as it was disturbed. With the exception of its gigantic tail, it has no weapon of defense; but with this appendage it can lash so terrific a blow as to lay low even a giant cave-bear, stunned and broken. It is a stupid, simple, gentle beast--one of the few within Caspak which such a description might even remotely fit. For three nights we slept in trees, finding no caves or other places of concealment. Here we were free from the attacks of the large land carnivora; but the smaller flying reptiles, the snakes, leopards, and panthers were a constant menace, though by no means as much to be feared as the huge beasts that roamed the surface of the earth. At the close of the third day Ajor and I were able to converse with considerable fluency, and it was a great relief to both of us, especially to Ajor. She now did nothing but ask questions whenever I would let her, which could not be all the time, as our preservation depended largely upon the rapidity with which I could gain knowledge of the geography and customs of Caspak, and accordingly I had to ask numerous questions myself. I enjoyed immensely hearing and answering her, so naive were many of her queries and so filled with wonder was she at the things I told her of the world beyond the lofty barriers of Caspak; not once did she seem to doubt me, however marvelous my statements must have seemed; and doubtless they were the cause of marvel to Ajor, who before had never dreamed that any life existed beyond Caspak and the life she knew.
