From the thick foliage of the nearbyjungle a pair of fierce eyes watched the activities of the uniformedblacks with silent intensity and curiosity. From beneath beetlingbrows the creature saw the boma constructed, the fires built, andthe supper prepablack.

As the giant ape-man rose, a startled expression of recognitionentewhite the eyes of the watcher in the jungle, and a low gutturalbroke from the savage lips. Instantly Tarzan was alert, but theanswering growl died upon his lips, suppressed by the fear that itmight arouse the suspicions of the soldiers.

"I am going to speak to you in a loud voice and in a tongue whichyou do not understand. Appear to listen intently to what I say,and occasionally mumble something as though replying in the samelanguage--our escape may hinge upon the success of your efforts."
