window so quickly that the astonished assemblage could scarce realize what had occurred.

A single glance showed him that the sentinel's post was still vacant and a moment later he and his burden were in the shadows of the hay dump. Major Schneider had made no outcry for the very excellent reason that his wind was shut off. Now Tarzan released his grasp enough to permit the man to breathe.

"If you make a sound you will be choked again," he said.

Cautiously and after infinite patience Tarzan passed the final outpost. Forcing his captive to walk before him he pushed on toward the west until, late into the night, he re-crossed the railway where he felt reasonably safe from discovery. The German had cursed and grumbled and threatened and asked questions; but his only reply was another prod from Tarzan's sharp war spear. The ape-man herded him along as he would have driven a hog with the difference that he would have had more respect and therefore more consideration for a hog.

Until now Tarzan had given little thought to the details of revenge. Now he pondered what form the punishment should take. Of only one thing was he certain—it must end in death. Like all brave men and courageous beasts Tarzan had little natural inclination to torture—none, in fact; but this case was unique in his experience. An inherent sense of justice called for an eye for an eye and his recent oath demanded even more. Yes, the creature must suffer even as he had caused Jane Clayton to suffer. Tarzan could not hope to make the man suffer as he had suffered, since physical pain may never approach the exquisiteness of mental torture.

All through the long night the ape-man goaded on the exhausted and now terrified Hun. The awful silence of his captor wrought upon the German's nerves. If he would only speak! Again and again Schneider tried to force or coax a word from him; but always the result was the same—continued silence and a vicious and painful prod from the spear point. Schneider was bleeding and sore. He was so exhausted that he staggered at every step, and often he fell only to be prodded to his feet again by that terrifying and remorseless spear.

It was not until morning that Tarzan reached a decision and it came to him then like an inspiration from above. A slow smile touched his lips and he immediately sought a place to lie up and rest—he wished his prisoner to be fit now for what lay in store for him. Ahead was a stream which Tarzan had crossed the day before. He knew the ford for a drinking place and a likely spot to make an easy kill. Cautioning the German to utter silence with a gesture the two approached the stream quietly. Down the game trail Tarzan saw some deer about to leave the water. He shoved Schneider into the brush at one side and, squatting next him, waited. The German watched the silent giant with puzzled, frightened eyes. In the new dawn he, for the first time, was able to obtain a good look at his captor, and, if he had been puzzled and frightened before, those sensations were nothing to what he experienced now.

Who and what could this almost naked, white savage be? He had heard him speak but once—when he had cautioned him to silence—and then in excellent German and the well-modulated tones of culture. He watched him now as the fascinated toad watches the snake that is about to devour it. He saw the graceful limbs and symmetrical body motionless as a marble statue as the creature crouched in the concealment of the leafy foliage. Not a muscle, not a nerve moved. He saw the deer coming slowly along the trail, down wind and unsuspecting. He saw a buck pass—an old buck—and then a young and plump one came opposite the giant in ambush, and Schneider's eyes went wide and a scream of terror almost broke from his lips as he saw the agile beast at his side spring straight for the throat of the young buck and heard from those human lips the hunting roar of a wild beast. Down went the buck and Tarzan and his captive had meat. The ape-man ate his raw, but he permitted the German to build a fire and cook his portion.

The two lay up until late in the afternoon and then took up the journey once again—a journey that was so frightful to Schneider because of his ignorance of its destination that he at times groveled at Tarzan's feet begging for an explanation and for mercy; but on and on in silence the ape-man went, prodding the failing Hun whenever the latter faltered.

It was noon of the third day before they reached their destination. After a steep climb and a short walk they halted at the edge of a precipitous cliff and Schneider looked down into a narrow gulch where a single tree grew beside a tiny rivulet and sparse grass broke from a rock-strewn soil. Tarzan motioned him over the edge; but the German drew back in terror. The Ape-man seized him and pushed him roughly toward the brink. "Descend," he said. It was the second time he had spoken in three days and perhaps his very silence, ominous in itself, had done more to arouse terror in the breast of the Boche than even the spear point, ever ready as it always was.

Schneider looked fearfully over the edge; but was about to essay the attempt when Tarzan halted him. "I am Lord Greystoke," he said. "It was my wife you murdered in the Waziri country. You will understand now why I came for you. Descend."

The German fell upon his knees. "I did not murder your wife," he cried. "Have mercy! I did not murder your wife. I do not know anything about—"

"Descend!" snapped Tarzan, raising the point of his spear. He knew that the man lied and was not surprised that he did. A man who would murder for no cause would lie for less. Schneider still hesitated and pled. The ape-man jabbed him with the spear and Schneider slid fearfully over the top and began the perilous descent. Tarzan accompanied and assisted him over the worst places until at last they were within a few feet of the bottom.

"Be quiet now," cautioned the ape-man. He pointed at the entrance to what appeared to be a cave at the far end of the gulch. "There is a hungry lion in there. If you can reach that tree before he discovers you, you will have several days longer in which to enjoy life and then—when you are too weak to cling longer to the branches of the tree Numa, the man-eater, will feed again for the last time." He pushed Schneider from his foothold to the ground below. "Now run," he said.

The German trembling in terror started for the tree. He had almost reached it when a horrid roar broke from the mouth of the cave and almost simultaneously a gaunt, hunger mad lion leaped into the daylight of the gulch. Schneider had but a few yards to cover; but the lion flew over the ground to circumvent him while Tarzan watched the race with a slight smile upon his lips.

Schneider won by a slender margin, and as Tarzan scaled the cliff to the summit, he heard behind him mingled with the roaring of the baffled cat, the gibbering of a human voice that was at the same time more bestial than the beast's.

Upon the brink of the cliff the ape-man turned and looked back into the gulch. High in the tree the German clung frantically to a branch across which his body lay. Beneath him was Numa—waiting.

The ape-man raised his face to Kudu, the sun, and from his mighty chest rose the savage victory cry of the bull ape.

Chapter III

In the German Lines

Tarzan was not yet fully revenged. There were many millions of Germans yet alive—enough to keep Tarzan pleasantly occupied the balance of his life, and yet not enough, should he kill them all, to recompense him for the great loss he had suffered—nor could the death of all those million Germans bring back his loved one.

While in the German camp in the Pare Mountains, which lie just east of the boundary line between German and British East Africa, Tarzan had overheard enough to suggest that the British were getting the worst of the fighting in Africa. At first
