the side of that bluff behind them. I could see the dirt
fly. I don't know what it could have been."

There was a slight rustling among the branches of the tree above
them and simultaneously a lithe, brown body dropped in their midst.
Hands moved quickly to the butts of pistols; but otherwise there
was no movement among the officers. First they looked wonderingly
at the almost naked white man standing there with the firelight
playing upon rounded muscles, took in the primitive attire and
the equally primitive armament and then all eyes turned toward the
colonel.

"Who the devil are you, sir?" snapped that officer.

"Tarzan of the Apes," replied the newcomer.

"Oh, Greystoke!" cried a major, and stepped forward with outstretched
hand.

"Preswick," acknowledged Tarzan as he took the proffered hand.

"I didn't recognize you at first," apologized the major. "The

Tarzan.

The colonel was about to reply when a new thought appeared to occur
to him and he looked quizzically at the ape-man. "Who brought you
here?" he asked. "Who passed you through our out-guards?"

"I have just come through the German lines and yours and passed
through your camp," he replied. "Send word to ascertain if anyone
saw me."

"But who accompanied you?" insisted Capell.

"I came alone," replied Tarzan and then, drawing himself to
his full height, "You men of civilization, when you come into the
jungle, are as dead among the quick. Manu, th
