"You tell me, I tell him," Rad said pompously. "No need yo'
'sturbing Massa Tom at dis hour."

"Koku go in!" declared the giant sternly.

"Jes' stay out dere on de stair an' res' yo'self," said Rad.

Koku lost his temper with old Rad. There was a feud between
them, although deep in their hearts they really were fond of each
other. But the two were jealous of each other's services to young
Tom Swift.

Suddenly Tom heard the old negro utter a frightened squeal. The
door which had been only ajar, burst inward and banged against
the door-stop with a mighty smash.

Rad went through the big bedroom like a chocolate-colored
streak, entered Tom's bathroom, and the next moment there was the
sound of crashing glass as Eradicate Sampson went through the
lower sash of the window, headfirst, out upon the roof of the
porch!

"What do you mean by this?" shouted Tom, sitting up in bed.

Koku paused in the doorway, bulking almost to the top of the
door. His right arm was drawn back, displaying his mighty biceps,
and he poised a ten foot spear with a copper head that he had
seized from a nest of such implements which was a decoration of
the lower hall.
