For several minutes he stood glaring at his foe, screaming hideous threats and insults at him. Then once more he charged. Again the painful point entered his body, but this time he pressed in clutching madly at the goad and for a hold upon Thandar's body. The latter held Thurg at arm's length, prodding him with the fire-hardened point of his wooden sword. The cave man's little brain wondered at the skill and prowess of this stranger who had struck him a single blow with a cudgel many moons before and then run like a rabbit to escape his wrath. Why was it that he did not run now? What strange change had taken place in him? He had expected an easy victim when he finally had recognized his foe; but instead he had met with brawn and ferocity equal to his own and with a strange weapon, the like of which he never before had seen. Thandar was puncturing him rapidly now, and Thurg was screaming in rage and suffering. Presently he could endure it no longer. With a sudden wrench he tore himself loose and ran, bellowing, through the jungle. Thandar did not pursue. It was enough that he had rid himself of his enemy. He turned toward Nadara, smiling. "It will seem very tame in Boston," he said; but though she gave him an answering smile, she did not understand, for to her Boston was but another land of primeval forests, and dense jungles; of hairy, battling men, and fierce beasts. At the edge of the forest they came again upon Thurg, but this time he was surrounded by a score of his burly tribesmen. Thandar knew better than to pit himself against so many. Thurg came rushing down upon them, his fellows at his heels. In loud tones he screamed anew his challenge, and the beasts behind him took it up until the forest echoed to their hideous bellowing. He had seen Nadara as he had battled with Thandar, and recognized her as the girl he had desired a year before--the girl whom this stranger had robbed him of. Now he was determined to wreak vengeance on the man and at the same time recapture the girl. Thandar and Nadara turned back into the jungle where but a single enemy could attack them at a time in the narrow trails. Here they managed to elude pursuit for several hours, coming again into the forest nearly a mile below the beach where the _Priscilla_ had lain at anchor. Thurg and his fellows had apparently given up the chase--they had neither seen nor heard aught of them for some time. Now the two hastened back through the wood to reach a point on the shore opposite the yacht. At last they came in sight of the harbor. Thandar halted. A look of horror and disappointment supplanted the expression of pleasurable anticipation that had lighted his countenance--the yacht was not there. A mile out they discerned her, steaming rapidly north. Thandar ran to the beach. He tore the black panther's hide from his shoulders, waving it frantically above his head, the while he shouted in futile endeavor to attract attention from the dwindling craft.
