don't let him come back in the shop here, until I get ready to
see him. I'll ring the bell when I am."

"All right, Mr. Tom."

Koku, very proud of his, mission of keeping guard over the
strange visitor, marched from the room with his big strides, his
long arms and powerful hands swinging at his sides, for Koku, or
August, as Tom had rechristened him, and as he often called him
(for it was in the month of August that he had located the
giants) was a very powerful man. A veritable giant, being
extremely tall, and big in proportion.

"Be sure. Don't let him in here, Koku!" called Tom, in an
additional warning, as his new servant left the main shop.

"Sure not!" exclaimed Koku, very earnestly.

"I don't know who he may be," mused Tom, as he began putting
away the parts to his new noiseless motor, so that the stranger
could not see them, and profit thereby. "It looks rather funny,
not sending in his name. It may be some one who thinks he can
spring a trick on me, and get some points about my inventions, or
dad's.

"It may even be somebody sent on by Andy Foger, or his father.
I can't be too careful. I'll just put everything away that isn't
fully covered by patents, and then if he wants to infringe on any
of the machines I can sue him."
