Too, there were many hybrid strains, not the least interesting of which to Tarzan was a yellow and black striped lion. Smaller than the species with which Tarzan was familiar, but still a most formidable beast, since it possessed in addition to sharp saber-like canines the disposition of a devil. To Tarzan it presented evidence that tigers had once roamed the jungles of Africa, possibly giant saber-tooths of another epoch, and these apparently had crossed with lions with the resultant terrors that he occasionally encountered at the present day. The true lions of this new, Old World differed but little from those with which he was familiar; in size and conformation they were almost identical, but instead of shedding the leopard spots of cubhood, they retained them through life as definitely marked as those of the leopard. Two months of effort had revealed no slightest evidence that she he sought had entered this beautiful yet forbidding land. His investigation, however, of the cannibal village and his questioning of other tribes in the neighborhood had convinced him that if Lady Jane still lived it must be in this direction that he seek her, since by a process of elimination he had reduced the direction of her flight to only this possibility. How she had crossed the morass he could not guess and yet something within seemed to urge upon him belief that she had crossed it, and that if she still lived it was here that she must be sought. But this unknown, untraversed wild was of vast extent; grim, forbidding mountains blocked his way, torrents tumbling from rocky fastnesses impeded his progress, and at every turn he was forced to match wits and muscles with the great carnivora that he might procure sustenance. Time and again Tarzan and Numa stalked the same quarry and now one, now the other bore off the prize. Seldom however did the ape-man go hungry for the country was rich in game animals and birds and fish, in fruit and the countless other forms of vegetable life upon which the jungle-bred man may subsist. Tarzan often wondered why in so rich a country he found no evidences of man and had at last come to the conclusion that the parched, thorn-covered steppe and the hideous morasses had formed a sufficient barrier to protect this country effectively from the inroads of mankind. After days of searching he had succeeded finally in discovering a pass through the mountains and, coming down upon the opposite side, had found himself in a country practically identical with that which he had left. The hunting was good and at a water hole in the mouth of a canyon where it debouched upon a tree-covered plain Bara, the deer, fell an easy victim to the ape-man's cunning.
