"I see," said Mr. Swift, and nodded.

"It interests me," admitted Tom. "As I say, I have given some thought to the electric locomotive."

"This is the age of speed," said Mr. Bartholomew earnestly. "Rapidity in handling freight and kindred things will be the salvation, and the only salvation, of many railroads. Tapping a rich territory is not enough. The road that can offer the quickest and cheapest service is the road that is going to keep out of a receivership. Believe me, I know!"

"You should," said Mr. Swift mildly. "Your experience should have taught you a great deal about the railroad business."

"It has. But that knowledge is worth just nothing at all without swift power and cheap traffic. Those are the problems today. Now, I am going to take a chance. If it doesn't work, my road is dished in any case. So I feel that the desperate chance is the only chance."

"What is that?" asked Tom Swift, sitting forward in his chair. "I, for one, feel so much interested that I will do anything in reason to find the answer to your traffic problem."

"That's the boy!" ejaculated Richard Bartholomew. "I will give it to you in a few words. If you will experiment with the electric locomotive idea, to develop speed and power over and above the Jandel patent, and will give me the first call on the use of any patents you may contrive, I will put up twenty-five thousand dollars in cash which shall be yours whether I can make use of a thing you invent or not."

"Any time limit in this agreement, Mr. Bartholomew?" asked Tom, making a few notes on a scratch pad before him on the library table.

"What do you say to three months?"

"Make it six, if you can," Tom said with continued briskness. "It interests me. I'll do my best. And I want you to get your money's worth."
