I need not describe, and after traveling a distance which I will not mention, in a direction which I withhold, we came at last to a tract of country which has never been described, nor, indeed, visited save by my unfortunate predecessor. Would you kindly look at this?”
He handed me a photograph – half-plate size.
“The unsatisfactory appearance of it is due to the fact,” said he, “that on descending the river the boat was upset and the case which contained the undeveloped films was broken, with disastrous results. Nearly all of them were totally ruined – an irreparable loss. This is one of the few which partially escaped. This explanation of deficiencies or abnormalities you will kindly accept. There was talk of faking. I am not in a mood to argue such a point.”
The photograph was certainly very off-colored. An unkind critic might easily have misinterpreted that dim surface. It was a dull gray landscape, and as I gradually deciphered the details of it I realized that it represented a long and enormously high line of cliffs exactly like an immense cataract seen in the distance, with a sloping, tree-clad plain in the foreground.
“I believe it is the same place as the painted picture,” said I.
“It is the same place,” the Professor answered. “I found traces of the fellow’s camp. Now look at this.”
It was a nearer view of the same scene, though the photograph was extremely defective. I could distinctly see the isolated, tree-crowned pinnacle of rock which was detached from the crag.
“I have no doubt of it at all,” said I.
“Well, that is something gained,” said he. “We progress, do we not? Now, will you please look at the top of that rocky pinnacle? Do you observe something there?”
“An enormous tree.”
“But on the tree?”
“A large bird,” said I.
He handed me a lens.
“Yes,” I said, peering through it, “a large bird stands on the tree. It appears to have a considerable beak. I should say it was a pelican.”
“I cannot congratulate you upon your eyesight,” said the Professor. “It is not a pelican, nor, indeed, is it a bird. It may interest you to know that I succeeded in shooting that particular specimen. It was the only absolute proof of my experiences which I was able to bring away with me.”
“You have it, then?” Here at last was tangible corro-boration.
“I had it. It was unfortunately lost with so much else in the same boat accident which ruined my photographs. I clutched at it as it disappeared in the swirl of the rapids, and part of its wing was left in my hand. I was insensible when washed ashore, but the miserable remnant of my superb specimen was still intact; I now lay it before you.”
From a drawer he produced what seemed to me to be the upper portion of the wing of a large bat. It was at least two feet in length, a curved bone, with a membranous veil beneath it.
“A monstrous bat!” I suggested.
“Nothing of the sort,” said the Professor, severely. “Living, as I do, in an educated and scientific atmosphere, I could not have conceived that the first principles of zoology were so little known. Is it possible that you do not know the elementary fact in comparative anatomy, that the wing of a bird is really the forearm, while the wing of a bat consists of three elongated fingers with membranes between? Now, in this case, the bone is certainly not the forearm, and you can see for yourself that this is a single membrane hanging upon a single bone, and therefore that it cannot belong to a bat. But if it is neither bird nor bat, what is it?”
My small stock of knowledge was exhausted.
“I really do not know,” said I.
He opened the standard work to which he had already referred me.
“Here,” said he, pointing to the picture of an extraordinary flying monster, “is an excellent reproduction of the dimorphodon, or pterodactyl, a flying reptile of the Jurassic period. On the next page is a diagram of the mechanism of its wing. Kindly compare it with the specimen in your hand.”
A wave of amazement passed over me as I looked. I was convinced. There could be no getting away from it. The cumulative proof was overwhelming. The sketch, the photographs, the narrative, and now the actual specimen – the evidence was complete. I said so – I said so warmly, for I felt that the Professor was an ill-used man. He leaned back in his chair with drooping eyelids and a tolerant smile, basking in this sudden gleam of sunshine.
“It’s just the very biggest thing that I ever heard of!” said I, though it was my journalistic rather than my scientific enthusiasm that was roused. “It is colossal. You are a Columbus of science who has discovered a lost world. I’m awfully sorry if I seemed to doubt you. It was all so unthinkable. But I understand evidence when I see it, and this should be good enough for anyone.”
The Professor purred with satisfaction.
“And then, sir, what did you do next?”
“It was the wet season, Mr Malone, and my stores were exhausted. I explored some portion of this huge cliff, but I was unable to find any way to scale it. The pyramidal rock upon which I saw and shot the pterodactyl was more accessible. Being something of a cragsman, I did manage to get half way to the top of that. From that height I had a better idea of the plateau upon the top of the crags. It appeared to be very large; neither to east nor to west could I see any end to the vista of green-capped cliffs. Below, it is a swampy, jungly region, full of snakes, insects, and fever. It is a natural protection to this singular country.”
“Did you see any other trace of life?”
“No, sir, I did not; but during the week that we lay encamped at the base of the cliff we heard some very strange noises from above.”
“But the creature that the American drew? How do you account for that?”
“We can only suppose that he must have made his way to the summit and seen it there. We know, therefore, that there is a way up. We know equally that it must be a very difficult one, otherwise the creatures would have come down and overrun the surrounding country. Surely that is clear?”
“But how did they come to be there?”
“I do not think that the problem is a very obscure one,” said the Professor; “there can only be one explanation. South America is, as you may have heard, a granite continent. At this single point in the interior there has been, in some far distant age, a great, sudden volcanic upheaval. These cliffs, I may remark, are basaltic, and therefore plutonic. An area, as large perhaps as Sussex, has been lifted up en blocwith all its living contents, and cut off by perpendicular precipices of a hardness which defies erosion from all the rest of the continent. What is the result? Why, the ordinary laws of Nature are suspended. The various checks which influence the struggle for existence in the world at large are all neutralized or altered. Creatures survive which would otherwise disappear. You will observe that both the pterodactyl and the stegosaurus are Jurassic, and therefore of a great age in the order of life. They have been artificially conserved by those strange accidental conditions.”
“But surely your evidence is conclusive. You have only to lay it before the proper authorities.”
“So in my simplicity, I had imagined,” said the Professor, bitterly. “I can only tell you that it was not so, that I was
