flight, while just behind him he pictured the ravenous carnivore thirsting for his blood. The fall of swiftly moving padded feet close behind him urged him to greater speed, the hot breath of the lion surged from the savage lungs to pound upon his ears like surf upon an ocean beach.
Such is the power of imagination. It is true that Numa was bounding along the bottom of the rift, but in the opposite direction to that in which Lafayette Smith bounded. Fortunately, for Lafayette , none of his wild shots had struck the lion; but the booming reverberation of the explosions in the narrow fissure had so surprised and unnerved him that he had wheeled and fled even as the man had.
Had the pursuit been as real as Lafayette imagined it, it could have urged him to no greater speed, nor could the consequent terror have nerved him to greater endurance; but physical powers have their limits, and presently the realization that his had about reached theirs forced itself upon Lafayette's consciousness and with it realization of the futility of further flight.
It was then that he turned to make his stand. He was trembling, but with fatigue rather than fear; and inwardly he was cool as he reloaded his revolver. He was surprised to discover that the lion was not on top of him, but he expected momentarily to see him appear where the fissure turned from his sight. Seating himself on a flat rock he waited the coming of the carnivore while he rested, and as the minutes passed and no lion came his wonderment increased.
Presently his scientific eye commenced to note the structure of the fissure's walls about him, and as his interest grew in the geologic facts revealed or suggested his interest in the lion waned, until, once again, the carnivore was relegated to the background of his consciousness, while in its place returned the momentarily forgotten plan to explore the rift to its farthest extent.
Recovered from the excessive fatigue of his strenuous exertion he undertook once more the exploration so rudely interrupted. Regained was the keen pleasure of discovery; forgotten, hunger, fatigue, and personal safety as he advanced along this mysterious path of adventure.
Presently the floor of the rift dropped rapidly until it was inclined at an angle that made progress difficult; and at the same time it narrowed, giving evidence that it might be rapidly pinching out. There was now barely width for him to squeeze forward between the walls when the fissure ahead of him became suddenly shrouded in gloom. Glancing up in search of an explanation of this new phenomenon Lafayette discovered that the walls far above were converging, until directly above him there was only a small streak of sky visible while ahead the rift was evidently closed entirely at the top.
As he pushed on, the going, while still difficult because of the steepness of the floor of the fissure, was improved to some extent by the absence of jumbled rocks underfoot, the closed ceiling of the corridor having offered no crumbling rim to the raging elements of the ages; but presently another handicap made itself evident— darkness, increasing steadily with each few yards until the man was groping his way blindly, though none the less determinedly, toward the unknown that lay ahead.
That an abyss might yawn beyond his next step may have occurred to him, but so impractical was he in all worldly matters while his scientific entity was in the ascendancy that he ignored the simplest considerations of safety. However, no abyss yawned; and presently, at a turning, daylight showed ahead. It was only a small patch of daylight; and when he reached the opening through which it shone it appeared, at first, that he had achieved the end of his quest—that he could proceed no farther.
Dropping to his hands and knees he essayed the feat of worming his way through the aperture, which he then discovered was amply large to accommodate his body; and a moment later he stood erect in astonished contemplation of the scene before him.
He found himself standing near the base of a lofty escarpment overlooking a valley that his practised eye recognized immediately as the crater of a long extinct volcano. Below him spread a panorama of rolling, tree-dotted landscape, broken by occasional huge outcroppings of weathered lava rock; and in the center a blue lake danced in the rays of an afternoon sun.
Thrilling to an identical reaction such as doubtless dominated Balboa as he stood upon the heights of Darien overlooking the broad Pacific, Lafayette Smith experienced that spiritual elation that is, perhaps, the greatest reward of the explorer. Forgotten, for the moment, was the scientific interest of the geologist, submerged by intriguing speculation upon the history of this lost valley, upon which, perhaps, the eyes of no other white man had ever gazed.
Unfortunately for the permanency of this beatific state of mind two other thoughts rudely obtruded themselves, as thoughts will. One appertained to the camp, for which he was supposed to be searching, while the other involved the lion, which was supposedly searching for him. The latter reminded him that he was standing directly in front of the mouth of the fissure, at the very spot where the lion would emerge were he following; and this suggested the impracticability of the fissure as an avenue of return to the opposite side of the crater wall.
A hundred yards away Smith espied a tree, and toward this he walked as offering the nearest sanctuary in the event the lion should reappear. Here, too, he might rest while considering plans for the future; and, that he might enjoy unmterrupted peace of mind while so engaged, he climbed up into the tree, where, straddling a limb, he leaned his back against the bole.
It was a tree of meager foliage, thus affording him an almost unobstructed view of the scene before him, and as has eyes wandered across the landscape they were arrested by something at the foot of the southern wall of the crater—something that did not perfectly harmonize with its natural surroundings. Here his gaze remained fixed as he sought to identify the thing that had attracted his attention. What it looked like he was positive that it could not be, so definitely had his preconception of the inaccessibility of the valley to man impressed itself upon his mind; yet the longer he looked the more convinced he became that what he saw was a small village of thatched huts.
And what thoughts did this recognition inspire? What noble and aesthetic emotions were aroused within his breast by the sight of this lonely village in the depths of the great crater which should, by all the proofs that he had seen, have been inaccessible to man?
No, you are wrong again. What it suggested was food. For the first time since he had become lost Lafayette Smith was acutely conscious of hunger, and when he recalled that it had been more than twenty-four hours since he had eaten anything more substantial than a few chocolates his appetite waxed ravenous. Furthermore, he suddenly realized that he was actually suffering from thirst.
At a little distance lay the lake. Glancing back toward the entrance to the fissure he discovered no lion; and so he dropped to the ground and set off in the direction of the water, laying his course so that at no time was he at any great distance from a tree.
The water was cool and refreshing; and when he had drunk his fill he became acutely conscious, for the first time during the day, of an overpowering weariness. The water had temporarily relieved the pangs of hunger, and he determined to rest a few minutes before continuing on toward the distant vifiage. Once again he assured himself that there was no pursuing lion in evidence; and then he stretched himself at full length in the deep grass that grew near the edge of the lake, and with a low tree as protection from the hot sun relaxed his tired muscles in much needed rest.
He had not intended to sleep; but his fatigue was greater than he had supposed, so that, with relaxation, unconsciousness crept upon him unawares. Insects buzzed lazily about him, a bird alighted in the tree beneath which he lay and surveyed him critically, the sun dropped lower toward the western rim, and Lafayette Smith slept on.
He dreamed that a lion was creeping toward him through high grass. He tried to rise, but he was powerless. The horror of the situation was intolerable. He tried to cry out and frighten the lion away, but no sound issued from his throat. Then he made a final supreme effort, and the shriek that resulted awakened him. He sat up, dripping with perspiration, and looked quickly and fearfully about him. There was no lion. 'Whew!' he exclaimed. 'What a relief.'
Then he glanced at the sun and realized that he had slept away the greater part of the afternoon. Now his hunger returned and with it recollection of the distant village. Rising, he drank again at the lake, and then started on his journey toward the base of the southern rim, where he hoped he would find friendly natives and food.
The way led for the greater part around the edge of the lake; and as dusk settled and then darkness it became more and more difficult to move except at a slow and cautious pace, since the ground was often strewn with fragments of lava that were not visible in the darkness.
Night brought the cheering sight of fires in the village; and these, seeming nearer than they really were, buoyed his spirits by the assurance that his journey was nearing completion. Yet, as he stumbled onward, the
