Immediately Tarzan was alert. He lifted his head and sniffed the slow, jungle breeze. What was it that had attracted Numa's attention and taken him soft-footed and silent away from the scene of his discomfiture?
Just as the lion disappeared among the trees beyond the clearing Tarzan caught upon the down-coming wind the explanation of his new interest—the scent spoor of man was wafted strongly to the sensitive nostrils. Caching the remainder of the deer's hind quarter in the crotch of a tree the ape-man wiped his greasy palms upon his naked thighs and swung off in pursuit of Numa. A broad, well-beaten elephant path led into the forest from the clearing. Parallel to this slunk Numa, while above him Tarzan moved through the trees, the shadow of a wraith. The savage cat and the savage man saw Numa's quarry almost simultaneously, though both had known before it came within the vision of their eyes that it was a black man. Their sensitive nostrils had told them this much and Tarzan's had told him that the scent spoor was that of a stranger—old and a male, for race and sex and age each has its own distinctive scent.
It was an old man that made his way alone through the gloomy jungle, a wrinkled, dried up, little old man hideously scarred and tattooed and strangely garbed, with the skin of a hyena about his shoulders and the dried head mounted upon his grey pate. Tarzan recognized the ear-marks of the witch-doctor and awaited Numa's charge with a feeling of pleasurable anticipation, for the ape-man had no love for witch-doctors; but in the instant that Numa did charge, the white man suddenly recalled that the lion had stolen his kill a few minutes before and that revenge is sweet.
