Part 20

"We have to bear in mind," remarked Summerlee, "that there are many prehistoric forms which have never come down to us. It would be rash to suppose that we can give a name to all that we are likely to meet." "Exactly. A rough classification may be the best that we can attempt. To-morrow some further evidence may help us to an identification. Meantime we can only renew our interrupted slumbers." "But not without a sentinel," said Lord John, with decision. "We can't afford to take chances in a country like this. Two-hour spells in the future, for each of us." "Then I'll just finish my pipe in starting the first one," said Professor Summerlee; and from that time onwards we never trusted ourselves again without a watchman. In the morning it was not long before we discovered the source of the hideous uproar which had aroused us in the night. The iguanodon glade was the scene of a horrible butchery. From the pools of blood and the enormous lumps of flesh scattered in every direction over the green sward we imagined at first that a number of animals had been killed, but on examining the remains more closely we discovered that all this carnage came from one of these unwieldy monsters, which had been literally torn to pieces by some creature not larger, perhaps, but far more ferocious, than itself. Our two professors sat in absorbed argument, examining piece after piece, which showed the marks of savage teeth and of enormous claws. "Our judgment must still be in abeyance," said Professor Challenger, with a huge slab of whitish-colored flesh across his knee. "The indications would be consistent with the presence of a saber-toothed tiger, such as are still found among the breccia of our caverns; but the creature actually seen was undoubtedly of a larger and more reptilian character. Personally, I should pronounce for allosaurus." "Or megalosaurus," said Summerlee. "Exactly. Any one of the larger carnivorous dinosaurs would meet the case. Among them are to be found all the most terrible types of animal life that have ever cursed the earth or blessed a museum." He laughed sonorously at his own conceit, for, though he had little sense of humor, the crudest pleasantry from his own lips moved him always to roars of appreciation. "The less noise the better," said Lord Roxton, curtly. "We don't know who or what may be near us. If this fellah comes back for his breakfast and catches us here we won't have so much to laugh at. By the way, what is this mark upon the iguanodon's hide?" On the dull, scaly, slate-colored skin somewhere above the shoulder, there was a singular black circle of some substance which looked like asphalt. None of us could suggest what it meant, though Summerlee was of opinion that he had seen something similar upon one of the young ones two days before. Challenger said nothing, but looked pompous and puffy, as if he could if he would, so that finally Lord John asked his opinion direct. "If your lordship will graciously permit me to open my mouth, I shall be happy to express my sentiments," said he, with elaborate sarcasm. "I am not in the habit of being taken to task in the fashion which seems to be customary with your lordship. I was not aware that it was necessary to ask your permission before smiling at a harmless pleasantry." It was not until he had received his apology that our touchy friend would suffer himself to be appeased. When at last his ruffled feelings were at ease, he addressed us at some length from his seat upon a fallen tree, speaking, as his habit was, as if he were imparting most precious information to a class of a thousand. "With regard to the marking," said he, "I am inclined to agree with my friend and colleague, Professor Summerlee, that the stains are from asphalt. As this plateau is, in its very nature, highly volcanic, and as asphalt is a substance which one associates with Plutonic forces, I cannot doubt that it exists in the free liquid state, and that the creatures may have come in contact with it. A much more important problem is the question as to the existence of the carnivorous monster which has left its traces in this glade. We know roughly that this plateau is not larger than an average English county. Within this confined space a certain number of creatures, mostly types which have passed away in the world below, have lived together for innumerable years. Now, it is very clear to me that in so long a period one would have expected that the carnivorous creatures, multiplying unchecked, would have exhausted their food supply and have been compelled to either modify their flesh-eating habits or die of hunger. This we see has not been so. We can only imagine, therefore, that the balance of Nature is preserved by some check which limits the numbers of these ferocious creatures. One of the many interesting problems, therefore, which await our solution is to discover what that check may be and how it operates. I venture to trust that we may have some future opportunity for the closer study of the carnivorous dinosaurs." "And I venture to trust we may not," I observed. The Professor only raised his great eyebrows, as the schoolmaster meets the irrelevant observation of the naughty boy. "Perhaps Professor Summerlee may have an observation to make," he said, and the two savants ascended together into some rarefied scientific atmosphere, where the possibilities of a modification of the birth-rate were weighed against the decline of the food supply as a check in the struggle for existence. That morning we mapped out a small portion of the plateau, avoiding the swamp of the pterodactyls, and keeping to the east of our brook instead of to the west. In that direction the country was still thickly wooded, with so much undergrowth that our progress was very slow. I have dwelt up to now upon the terrors of Maple White Land; but there was another side to the subject, for all that morning we wandered among lovely flowers--mostly, as I observed, white or yellow in color, these being, as our professors explained, the primitive flower-shades. In many places the ground was absolutely covered with them, and as we walked ankle-deep on that wonderful yielding carpet, the scent was almost intoxicating in its sweetness and intensity. The homely English bee buzzed everywhere around us. Many of the trees under which we passed had their branches bowed down with fruit, some of which were of familiar sorts, while other varieties were new. By observing which of them were pecked by the birds we avoided all danger of poison and added a delicious variety to our food reserve. In the jungle which we traversed were numerous hard-trodden paths made by the wild beasts, and in the more marshy places we saw a profusion of strange footmarks, including many of the iguanodon. Once in a grove we observed several of these great creatures grazing, and Lord John, with his glass, was able to report that they also were spotted with asphalt, though in a different place to the one which we had examined in the morning. What this phenomenon meant we could not imagine. We saw many small animals, such as porcupines, a scaly ant-eater, and a wild pig, piebald in color and with long curved tusks. Once, through a break in the trees, we saw a clear shoulder of green hill some distance away, and across this a large dun-colored animal was traveling at a considerable pace. It passed so swiftly that we were unable to say what it was; but if it were a deer, as was claimed by Lord John, it must have been as large as those monstrous Irish elk which are still dug up from time to time in the bogs of my native land. Ever since the mysterious visit which had been paid to our camp we always returned to it with some misgivings. However, on this occasion we found everything in order. That evening we had a grand discussion upon our present situation and future plans, which I must describe at some length, as it led to a new departure by which we were enabled to gain a more complete knowledge of Maple White Land than might have come in many weeks of exploring. It was Summerlee who opened the debate. All day he had been querulous in manner, and now some remark of Lord John's as to what we should do on the morrow brought all his bitterness to a head. "What we ought to be doing to-day, to-morrow, and all the time," said he, "is finding some way out of the trap into which we have fallen. You are all turning your brains towards getting into this country. I say that we should be scheming how to get out of it." "I am surprised, sir," boomed Challenger, stroking his majestic beard, "that any man of science should commit himself to so ignoble a sentiment. You are in a land which offers such an inducement to the ambitious naturalist as none ever has since the world began, and you suggest leaving it before we have acquired more than the most superficial knowledge of it or of its contents. I expected better things of you, Professor Summerlee." "You must remember," said Summerlee, sourly, "that I have a large class in London who are at present at the mercy of an extremely inefficient locum tenens. This makes my situation different from yours, Professor Challenger, since, so far as I know, you have never been entrusted with any responsible educational work." "Quite so," said Challenger. "I have felt it to be a sacrilege to divert a brain which is capable of the highest original research to any lesser object. That is why I have sternly set my face against any proffered scholastic appointment." "For example?" asked Summerlee, with a sneer; but Lord John hastened to change the conversation. "I must say," said he, "that I think it would be a mighty poor thing to go back to London before I know a great deal more of this place than I do at present." "I could never dare to walk into the back office of my paper and face old McArdle," said I. (You will excuse the frankness of this report, will you not, sir?) "He'd never forgive me for leaving such unexhausted copy behind me. Besides, so far as I can see it is not worth discussing, since we can't get down, even if we wanted." "Our young friend makes up for many obvious mental lacunae by some measure of primitive common sense," remarked Challenger. "The interests of his deplorable profession are immaterial to us; but, as he observes, we cannot get down in any case, so it is a waste of energy to discuss it." "It is a waste of energy to do anything else," growled Summerlee from behind his pipe. "Let me remind you that we came here upon a perfectly definite mission, entrusted to us at the meeting of the Zoological Institute in London. That mission was to test the truth of Professor Challenger's statements. Those statements, as I am bound to admit, we are now in a position to endorse. Our ostensible work is therefore done. As to the detail which remains to be worked out upon this plateau, it is so enormous that only a large expedition, with a very special equipment, could hope to cope with it. Should we attempt to do so ourselves, the only possible result must be that we shall never return with the important contribution to science which we have already gained. Professor Challenger has devised means for getting us on to this plateau when it appeared to be inaccessible; I think that we should now call upon him to use the same ingenuity in getting us back to the world from which we came." I confess that as Summerlee stated his view it struck me as altogether reasonable. Even Challenger was affected by the consideration that his enemies would never stand confuted if the confirmation of his statements should never reach those who had doubted them. "The problem of the descent is at first sight a formidable one," said he, "and yet I cannot doubt that the intellect can solve it. I am prepared to agree with our colleague that a protracted stay in Maple White Land is at present inadvisable, and that the question of our return will soon have to be faced. I absolutely refuse to leave, however, until we have made at least a superficial examination of this country, and are able to take back with us something in the nature of a chart."
