"The original bequest has been increased until now the Institution has use of the income on a million dollars. You'll be surprised to know how much real work has been done by this very little advertised branch of our government. For example, out of the system of weather observation developed by the Institution grew the United States Weather Bureau. The United States Ethnological Research is all done by us--as witness the monumental studies of our American Indians. Powell's great explorations were fathered by the Smithsonian and so were Langley's experiments in flying machines as well as his studies of solar heat."
"My word!" exclaimed Roger, "so they were!"
"When I was in the northern part of the state, last summer, studying certain Indian mounds, I ran across one of your fellow instructors who mentioned your work in heat engineering. I've always been much interested in that line of research, so when I came West again I tried to get in touch with you."
"I'm not hard to reach, surely," said Roger.
"Oh, yes, you are," returned Austin.
"It was this way, Rog," Ernest's lazy, gentle voice interrupted. "I kept Dr. Austin away from you until I felt that there was some hope. I didn't want you to have another disappointment."
"As I got your idea from Mr. Wolf, it seems to me that the Smithsonian might be glad to back you in further experiments," said Austin.
Roger's thin face flushed as it was apt to do when his work was under discussion. "This is mighty kind of you, Dr. Austin, but my work has gone beyond the experimental stage. I'm ready to erect Solar Power Plants if I can find the money."
"Rog, you're not ready!" cried Ernest, with unusual vehemence. "You've no idea of the troubles you'll be up against when you try actually to erect a working plant, in a hot country."
"I'm not afraid," returned Roger shortly. "One thing is certain, I'm not going on experimenting any longer."
"My understanding of your device is, that it is practical only in tropical or semi-tropical climates," said Austin.
"This first device is, yes," answered Roger shortly. "If I can ever get this one launched, I shall take up other climates."
Austin eyed Roger keenly for a moment, then he said suddenly, "Why don't you let me see your plans? We might possibly have something to say that would interest you."
"Oh, of course! I wish I had some of them here. And it's too late to go up to the laboratory to-night."
"Wait a moment, Roger! Wait a moment," exclaimed Ernest. "Praying that we'd get to this point to-night, I brought down a set of drawings." He unlocked a drawer of the table and pulled out a roll of paper.
