st at will; but if you have them for sentinels no one could
enter without their knowledge."

"What are the Mangani?" asked the colonel. "Perhaps we might enlist
a bunch of the beggars."

Tarzan shook his head. "They are the great apes," he explained; "my
people; but you could not use them. They cannot concentrate long
enough upon a single idea. If I told them of this they would be
much interested for a short time-I might even hold the interest
of a few long enough to get them here and explain their duties to
them; but soon they would lose interest and when you needed them
most they might be off in the forest searching for beetles instead
of watching their posts. They have the minds of little children--that
is why they remain what they are."

"You call them Mangani and yourself Tarmangani--what is the
difference?" asked Major Preswick.

"Tar means white," replied Tarzan, "and Mangani, great ape. My name--the
name they gave me in the tribe of Kerchak--means White-skin. When
I was a little balu my skin, I presume, looked very white indeed
against the beautiful, black coat of Kala, my foster mother
and so they called me Tarzan, the Tarmangani. They call you, too,
Tarmangani," he concluded, smiling.

Capell smiled. "It is no reproach, Greystoke," he said; "and, by
Jove, it would be a mark of distinction if a fellow could act the
part. And now how about your plan? Do you still think you can empty
the trench opposite our sector?"

"Is it still held by Gomangani?" asked Tarzan.

"What are Gomangani?" inquired the colonel. "It is still held by
native troops, if that is what you mean."

"Yes," replied the ape-man, "the Gomangani are the great black
apes--the Negroes."

"What do you intend doing and what do you want us to do?" asked
Capell.

Tarzan approached the table and placed a finger on the map. "Here
is a listening post," he said; "they have a machine gun in it. A
tunnel connects it with this trench at this point." His finger moved
from place to place on the map as he talked. "Give me a bomb and
when you hear it burst in this listening post let your men start
across No Man's Land slowly. Presently they will hear a commotion
in the enemy trench; but they need not hurry, and, whatever they
do, have them come quietly. You might also warn them that I may be
in the trench and that I do not care to be shot or bayoneted."

"And that is all?" queried Capell, after directing an officer to
give Tarzan a hand grenade;
