as two shadows among the myriad shadows of the forest. Alert as his eyes and ears, was Tarzan's patrician nose. The spoor was fresh, and now that they had passed from the range of the strong ape odor of the tribe he had little difficulty in following Toog and Teeka by scent alone. Teeka's familiar scent spoor told both Tarzan and Taug that they were upon her trail, and soon the scent of Toog became as familiar as the other.
They were progressing rapidly when suddenly dense clouds overcast the sun. Tarzan accelerated his pace. Now he fairly flew along the jungle trail, or, where Toog had taken to the trees, followed nimbly as a squirrel along the bending, undulating pathway of the foliaged branches, swinging from tree to tree as Toog had swung before them; but more rapidly because they were not handicapped by a burden such as Toog's.
Tarzan felt that they must be almost upon the quarry, for the scent spoor was becoming stronger and stronger, when the jungle was suddenly shot by livid lightning, and a deafening roar of thunder reverberated through the heavens and the forest until the earth trembled and shook. Then came the rain—not as it comes to us of the temperate zones, but as a mighty avalanche of water—a deluge which spills tons instead of drops upon the bending forest giants and the terrified creatures which haunt their shade.
