age, cunning, and ferocity that the first law of nature imparts
to many beasts.

Lowering his bull head he charged for the ape-man and in the center
of the floor the two clinched. There they stood locked and swaying
for a moment until Tarzan succeeded in forcing his antagonist backward
over a table which crashed to the floor, splintered by the weight
of the two heavy bodies.

The girl stood watching the battle with wide eyes. She saw the two
men rolling hither and thither across the floor and she heard with
horror the low growls that came from the lips of the naked giant.
Schneider was trying to reach his foe's throat with his fingers
while, horror of horrors, Bertha Kircher could see that the other
was searching for the German's jugular with his teeth!

Schneider seemed to realize this too, for he redoubled his efforts
to escape and finally succeeded in rolling over on top of the ape-man
and breaking away. Leaping to his feet he ran for the window; but
the ape-man was too quick for him and before he could leap through

followed him, and once again they locked, dealing each other terrific
blows, until Schneider in a piercing voice screamed, "Kamerad!

Tarzan grasped the man by the throat and drew his hunting knife.
Schneider's back was against the wall so that though his knees

"Thus you slew my mate," he hissed in a terrible voice. "Thus
shall you die!"

The girl staggered forward. "Oh, God, no!" she cried. "Not that.
You are too brave--you cannot be such a beast as that!"

Tarzan turned at her. "No," he said, "you are right, I cannot do
it--I am no German," and he raised the point of his blade and sunk
it deep into the putrid heart of Hauptmann Fritz Schneider, putting
a bloody period to the Hun's last gasping cry: "I did not do it!
She is not--"

Then Tarzan turned toward the girl and held out his hand. "Give
me my locket," he said.

She pointed toward the dead officer. "He has it." Tarzan searched
him and found the trinket. "Now you may give me the papers," he said
to the girl, and without a word she handed him a folded document.

For a long time he stood looking at her before ho spoke again.

"I came for you, too," he said. "It would be difficult
