Stern knew at a glance the leaf was the rudely cured product of some degenerated tobacco-plant. He saw a glow of red at the tip of the close-rolled tobacco. Vapor issued from the chief's slit-mouth.

“Good Lord--he's--smoking!” stammered the engineer. “And that means--means an almost human brain. And--quick, Beatrice, the water! I didn't expect this! Thought they were all alike. Back to the tower, quick! Here, fill the pail--I'll keep him covered!”

Up he brought the automatic, till the bead lay fair upon the naked, muscular breast of the obeah.

Beatrice handed Stern the rifle, then snatching the pail, dipped it, filled it to the brim. Stern heard the water lap and gurgle. He knew it was but a few seconds, yet it seemed an hour to him, at the very least.

Keener than ever before in his whole life, his mental pictures now limned themselves with lightning rapidity upon his brain.

Stamped on his consciousness was this lithe, lean, formidable body, showing beyond dispute its human ancestry; the right hand that held a steel-pointed spear; the horrible ornament (a withered little smoked hand) that dangled from the left wrist by a cord of platted fiber.

Vividly Stern beheld a deep gash or scar that ran from the chief's right eye--a dull, fishlike eye, evidently destroyed by that wound--down across the leathery cheek, across the prognathous jaw; a reddish-purple wale, which on that clay-blue skin produced an effect indescribably repulsive.

Then the chief grunted, and moved forward, toward them. Stern saw that the gait was almost human, not shuffling and uncertain like that of the others, but firm and vigorous. He estimated the height at more than five feet, eight inches; the weight at possibly one hundred and forty pounds. Even at that juncture, his scientific mind, always accustomed to judging, instinctively registered these data, with the others.

“Here, you, get back there!” shouted Stern, as the girl rose again from filling the pail.

The cry was instinctive, for even as he uttered it, he knew it could not be understood. A thousand years of rapid degeneration had long wiped all traces of English speech from the brute-men, who now, at most, chattered some bestial gibberish. Yet the warning echoed loudly through Madison Forest; and the obeah hesitated.
