It was, as he had thought, a huge wolf, a pre-historic but gigantic counterpart of our own timber wolf. No need had the codon to run in packs, for in size, strength, ferocity and courage it was a match for any creature that it sought to bring down, with the possible exception of the mammoth, and this great beast alone it hunted in packs. The codon stood snarling beneath a great tree, occasionally leaping high against the bole as though he sought to reach something hidden by the foliage above. Tanar crept closer and presently he saw the figure of a youth crouching among the lower branches above the codon. It was evident that the boy was terror-stricken, but the thing that puzzled Tanar was that he cast affrighted glances upward into the tree more often than he did downward toward the codon, and presently this fact convinced the Sarian that the youth was menaced by something above him. Tanar viewed the predicament of the boy and then considered the pitiful inadequacy of his own makeshift bow and arrow, which might only infuriate the beast and turn it upon himself. He doubted that the arrows were heavy enough, or strong enough, to pierce through the savage heart and thus only might he hope to bring down the codon. Once more he crept to a new position, without attracting the attention either of the codon or the youth, and from this new vantage point he could look further up into the tree in which the boy crouched and then it was that he realized the hopelessness of the boy’s position, for only a few feet above him and moving steadily closer appeared the head of a great snake, whose wide, distended jaws revealed formidable fangs. Tanar’s consideration of the boy’s plight was influenced by a desire to save him from either of the two creatures that menaced him and also by the hope that if successful he might win sufficient gratitude to enlist the services of the youth as a guide, and especially as a go-between in the event that he should come in contact with natives of the island. Tanar had now crept to within seven paces of the codon, from the sight of which he was concealed by a low shrub behind which he lay. Had the youth not been so occupied between the wolf and the snake he might have seen the Sarian, but so far he had not seen him. Fitting an arrow to his crude bow and inserting four others between the fingers of his left hand, Tanar arose quietly and drove a shaft into the back of the codon, between its shoulders. With a howl of pain and rage the beast wheeled about, only to receive another arrow full in the chest. Then his glaring eyes alighted upon the Sarian and, with a hideous growl, he charged.
