Moving northward along the lower slopes of a conical mountain, the mind of the geologist became more and more deeply engrossed in the rocky story that Nature had written upon the landscape, a story so thrilling that even thoughts of camp were forgotten; and as he made his way farther and farther from camp a great lion stalked in his wake.
What hidden urge prompted Numa thus to follow the man-thing perhaps the great cat, himself, could not have guessed. He was not hungry, for he had but recently finished a kill, nor was he a man-eater, though a properly balanced combination of circumstances might easily find the scales tipped in that direction by hunger, inevitable and oft recurring. It may have been only curiosity, or, again, some motive akin to that playfulness which is inherent in all cats.
For an hour Numa followed the man—an hour of intense interest for both of them—an hour that would have been replete with far greater interest for the man, if less pleasurable, had he shared with Numa the knowledge of their propinquity. Then the man halted before a narrow vertical cleft in the rocky escarpment towering above him. Here was an interesting entry in the book of Nature! What titanic force had thus rent the solid rock of this mighty mountain? It had its own peculiar significance, but what was it? Perhaps elsewhere on the face of the mountain, that here became precipitous, there would be other evidence to point the way to a solution. Lafayette Smith looked up at the face of the cliff towering above him, he looked ahead in the direction he had been going; and then he looked back in the direction from which he had come—and saw the lion.
For a long moment the two stared at one another. Surprise and interest were the most definitely registered of the emotions that the discovery engendered in the mind of the man. Suspicion and irritability were aroused in Numa.
"Most interesting," thought Lafayette Smith. "A splendid specimen;" but his interest in lions was purely academic, and his thoughts quickly reverted to the more important phenomenon of the crack in the mountain, which now, again, claimed his undivided attention. From which it may be inferred that Lafayette Smith was either an inordinately courageous man or a fool. Neither assumption, however, would be wholly correct, especially the latter. The truth of the matter is that Lafayette Smith suffered from inexperience and impracticality. While he knew that a lion was, per se, a threat to longevity he saw no reason why this lion should attack him. He, Lafayette Smith, had done nothing to offend this, or any other, lion; he was attending to his own affairs and, like the gentleman he was, expected others, including lions, to be equally considerate. Furthermore, he had a childlike faith in the infallibility of his nickel plated .32 should worse develop into worst. Therefore he ignored Numa and returned to contemplation of the intriguing crack.
It was several feet wide and was apparent as far up the face of the cliff as he could see. Also there was every indication that it continued far below the present surface of the ground, but had been filled by débris brought down by erosion from above. How far into the mountain it extended he could not guess; but he hoped that it ran back, and was open, for a great distance, in which event it would offer a most unique means for studying the origin of this mountain massif.
Therefore, with this thought uppermost in his mind, and the lion already crowded into the dim background of his consciousness, he entered the narrow opening to the intriguing fissure. Here he discovered that the cleft curved gradually to the left and that it extended upward to the surface, where it was considerably wider than at the bottom, thus affording both light and air for the interior.
Thrilled with excitement and glowing with pride in his discovery, Lafayette clambered inward over the fallen rocks that littered the floor of the fissure, intent now on exploring the opening to its full extent and then working back slowly to the entrance in a more leisurely manner, at which time he would make a minute examination of whatever geological record Nature had imprinted upon the walls of this majestic corridor. Hunger, thirst, camp, and the lion were forgotten.
Numa, however, was no geologist. The great cleft aroused no palpitant enthusiasm within his broad breast. It did not cause him to forget anything, and it intrigued his interest only to the extent of causing him to speculate on why the man-thing had entered it. Having noted the indifferent attitude of the man, his lack of haste, Numa could not attribute his disappearance within the maw of the fissure to flight. All of his life things had been fleeing from him.
It had always seemed to Numa an unfair provision of Nature that things should so almost inevitably seek to escape him, especially those things he most coveted. There were, for example, Pacco, the zebra, and Wappi, the antelope, the tenderest and most delicious of his particular weaknesses, and, at the same time, the fleetest. It would have been much simpler all around had Kota the tortoise been endowed with the speed of Pacco and Pacco with the torpidity of Kota.
