he never would, become entirely civilized.

He was naturally a born tracker of men. For generations his

them, of civilized men could live in anything like harmony.

That somebody should prowl about the Swift house at night with
a desire to rob his young master or injure him, did not surprise
Koku in the least. He accepted the fact of the marauder's
presence as quite the expected thing.

But the man who had robbed Tom and later tried to repay him for
playing what appeared to be a practical joke on the robber, did
not trouble the Swift premises with his presence before morning.
Koku, thrusting Eradicate Sampson aside and striding to his
bedroom to report this fact, was what awoke Tom at eight o'clock.

"Hey! What you want, tromping in here for, man?" demanded old
Rad angrily. "An' totin' that spear, too. Where you t'ink yo' is?
In de jungle again? Go 'way, chile!"

Both Rad and Koku were rapidly outliving the sudden friendship
of Rad's sick days, when it was thought he might be blind for
life, and were dropping back into their old ways of bickering and
rivalry for Tom's attention.

"I report to the Master," declared the giant, in his deep
voice.
