Following that winding path through the twilight dimness of the big pines, McGrath did not find it in his soul to marvel that black slimy tentacles from the depths of Africa had stretched across the world to breed nightmares in an alien land. Certain natural conditions produce certain effects, breed certain pestilences of body or mind, regardless of their geographical situation. The river-haunted pinelands were as abysmal in their way as were the reeking African jungles. The trend of the trail was away from the river. The land sloped very gradually upward, and all signs of marsh vanished. * * * * * The trail widened, showing signs of frequent use. McGrath became nervous. At any moment he might meet someone. He took to the thick woods alongside the trail, and forced his way onward, each movement sounding cannon-loud to his whetted ears. Sweating with nervous tension, he came presently upon a smaller path, which meandered in the general direction he wished to go. The pinelands were crisscrossed by such paths. He followed it with greater ease and stealth, and presently, coming to a crook in it, saw it join the main trail. Near the point of junction stood a small log cabin, and between him and the cabin squatted a big black man. This man was hidden behind the bole of a huge pine beside the narrow path, and peering around it toward the cabin. Obviously he was spying on someone, and it was quickly apparent who this was, as John De Albor came to the door and stared despairingly down the wide trail. The black watcher stiffened and lifted his fingers to his mouth as if to sound a far-carrying whistle, but De Albor shrugged his shoulders helplessly and turned back into the cabin again. The negro relaxed, though he did not alter his vigilance. What this portended, McGrath did not know, nor did he pause to speculate. At the sight of De Albor a red mist turned the sunlight to blood, in which the black body before him floated like an ebony goblin. A panther stealing upon its kill would have made as much noise as McGrath made in his glide down the path toward the squatting black. He was aware of no personal animosity toward the man, who was but an obstacle in his path of vengeance. Intent on the cabin, the black man did not hear that stealthy approach. Oblivious to all else, he did not move or turn--until the pistol butt descended on his woolly skull with an impact that stretched him senseless among the pine needles.
