"Well, Sir, so you're one of Erskine's men. Ought to be good. Solar engine, though, doesn't sound cheerful. What's the idea?"
Roger unrolled his drawings and began his explanations. Haskell listened with keen interest, asking questions now and again. When Roger, flushed of cheek, had finished, Haskell lighted his cigar, which had gone out.
"Very clever! Very clever! A nice little experiment. What do you want to do with it?"
"I want you to manufacture and sell these solar heat plants," replied Roger boldly.
"I see. But are you sure such a plant is practicable?"
"Absolutely!"
"Where have you had one working?"
"At the University."
"You mean in the laboratory."
Roger nodded. Haskell cleared his throat and looked over Roger's black head for a minute, then he said: "My dear fellow, I am a business man, not a philanthropist. When you can come to me and say, 'I've got a plant in Texas and one in Mississippi and one in Egypt and they've worked for, say two years, and the folks want more,' why, then you'll interest me. But I don't see putting a hundred thousand dollars into a laboratory experiment, however clever."
Roger's clear blue eyes, still unsophisticated despite his twenty-five years, did not flinch. There was a perceptible pause, however, before he said: "But, Mr. Haskell, how am I going to get a dozen plants into use unless some one manufactures and installs them for me?"
"Some one will have to do just that. But you'll have to pay for it."
"But I thought great concerns like yours," persisted Roger, "were constantly looking for new developments."
"We are. But frankly, Mr. Moore, your whole idea is too visionary. Some day, undoubtedly, we shall have solar engineering. But that day is several generations away. We have coal and all its by-products and water power is just beginning to come into its own."
"Coal would have to retail at a dollar a ton to compete with my solar device in a hot climate," interrupted Roger.
"Very interesting if true! But you've erected no plant in a hot climate. I'll tell you what I will do though, Mr. Moore. I could very well use your unusual knowledge of heat transmission in my concern. I'll give you three thousand a year to begin with."
Roger got slowly to his feet, rolling up his drawings. "Thank you, Mr. Haskell. But I think I'll stick to my solar engine."
Haskell rose too. "An inventor's life is hell, my boy. Better come in out of the rain."
"But why should it be hell?" asked Roger. "The inventor is the very backbone of the industrial life of the world."
