"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 to start day after to-morrow."

"All right, dad. I can start now, if you say so."
