Tarzan, inured to hardship and to long and rapid marches, fell into a dog-trot such as he could keep up for hours at a time without rest, while his guides, trotting their graceful mounts, kept just ahead of him. The plain was more rolling than it had appeared from the verge of the forest, with here and there a clump of trees; the grass was plentiful and there were occasional bands of the larger species of antelope grazing at intervals. At sight of the approaching riders and the comparatively giantlike figure of Tarzan they broke and ran. Once they passed a rhinoceros, the party making only a slight detour to avoid it, and later, in a clump of trees, the leader halted his detachment suddenly and seizing his lance advanced again slowly toward a clump of bushes at the same time transmitting an order to his men which caused them to spread and surround the thicket. Tarzan halted and watched the proceedings. The wind was blowing from him in the direction of the thicket, so that he could not determine what manner of creature, if any, had attracted the attention of the officer; but presently, when the warriors had completely surrounded the bushes and those upon the other side had ridden into it, their spears couched and ready, he heard an ugly snarl issuing from the center of the thicket and an instant later an African wild cat sprang into view, leaping directly at the officer waiting with ready spear to receive it. The weight and momentum of the beast all but unseated the rider, the point of whose spear had met the cat full in the chest. There were a few spasmodic struggles before death ensued, during which, had the spear broken, the man would have been badly mauled and perhaps killed, for the cat was relatively as formidable a beast as is the lion to us. The instant that it died four warriors leaped forward and with their sharp knives removed the head and skin in an incredibly short time. Tarzan could not but note that everything these people did was accomplished with maximum efficiency. Never did there seem to be any lost motion, never was one at a loss as to what to do, never did one worker get in the way of another. Scarcely ten minutes had elapsed from the moment that they had encountered the cat before the detachment was again moving, the head of the beast fastened to the saddle of one of the warriors, the skin to that of another.
