piece of rubber, came no farther, and dripped off on the ground. It
did not run down the sleeve of Eradicate.

"Well, I 'clar t' goodness! That suttinly am a mighty fine charm!"
cried the colored man. "Yo' suah am a pert gen'men, all right. Now I
kin work widout stoppin' t' empty mah sleeve ob lime juice ebery
minute. I'se suttinly obliged t' yo'."

"You're welcome, I'm sure," replied Tom. "I think some day I'll
invent a machine for whitewashing, and then--"

"Doan't do dat! Doan't do dat!" begged Eradicate earnestly. "Dis,
an' makin' dirt disappear, am de only perfessions I got. Doan't go
'ventin' no machine, Mistah Swift."

"All right. I'll wait until you get rich."

"Ha, ha! Den yo' gwine t' wait a pow'ful long time," chuckled
Eradicate as he went on with his whitewashing.

Tom went into the house. He found his father busy with some papers
at his desk.

"Ah, it's you, is it, Tom?" asked the inventor, looking up. "I was
just wishing you would come in."

"What for, dad?"

"Well, I have quite an important mission for you. I want you to go
on a journey."

"A journey? Where?"

"To Albany. You see, I've been thinking over matters, and I have
been in correspondence with my lawyers in regard to my turbine
motor. I must take measures to protect myself. You know I have not
yet taken out a complete patent on the machine. I have not done so
because I did not want to put my model on exhibition in Washington.
I was afraid some of those unscrupulous men would take advantage of
me. Another point was that I had not perfected a certain device that
goes on the motor. That objection is now removed, and I am ready to
send my model to Washington, and take out the complete patent."

"But I thought you said you wanted me to go to Albany."

"So I do. I will explain. I have just had a letter from Reid &
Crawford, my Washington attorneys. Mr. Crawford, the junior member
of the firm, will be in Albany this week on some law business. He
agrees to receive my model and some papers there, and take them back
to Washington with him. In this way they will be well protected. You
see, I have to be on my guard, and if I send the model to Albany,
instead of the national capital, I may throw the plotters off the
track, for I feel that they are watching every move I make. As soon
as you or I should start for Washington they would be on our trail.
But you can go to Albany unsuspected. Mr. Crawford will wait for you
there. I want you
