"The patents won't cost a great deal, if you do the work yourself, Roger," said the Dean. "But it's going to take time to learn the patent game." "Well," said Roger, with a sigh, "if I've got to become a patent attorney in order to patent my ideas, I suppose I can. But gee, I am glad I don't want to get married. You were wise in not letting me give up that instructorship, Dean, as I wanted to." Dean Erskine smiled ruefully. "Seems to have been about the only sane advice I've given you." "Don't you think it, sir!" exclaimed Roger. "If I ever do get away with this, yours will be the credit." "And Ernest's," added the Dean. "You bet, Ernest! And now, I'm going out to the University library and read up on patents," said Roger, with the familiar squaring of the shoulders. He had need to square his shoulders: a greater need than either he or his two devoted friends could dream. For as the months slipped into years, it seemed more and more obvious that either Roger's ideas were utterly impractical or else that he was actually several generations ahead of his time. In his brilliant, yet thoroughgoing way, Roger studied patent law and registered two years after his trip to Chicago _as_ a patent attorney in Washington. He worked constantly on the development of his plant, improving here, discarding there, until he had reached the point, he felt, where he could do no more until he had funds for a practical plant, in a hot climate. He and the Dean and Ernest estimated that not less than fifty thousand dollars would be essential for such an initial plant. The sum might have been fifty million for all its accessibility to Roger. Most of the wealthy men whom Roger was able to reach admitted the cleverness and the interest of his ideas. None of them could be persuaded that the idea would be a good investment. Once in desperation Roger went to Chicago to a firm whose letter heads read "Bankers, Stocks and Bonds, Promoters, Investments." Roger was turned over to a young man who wore a garnet ring and who was at the head of the Engineering Investments Department. The two had several long sessions. Then the man of the garnet ring proposed that a company be organized for half a million dollars and that his company undertake to sell the stock. Roger was much encouraged. "That's fine," he said. "How long would it take to raise fifty thousand dollars?" "Not long," replied the young promoter, whose name was Eaton. "Of course, you understand that the first money will have to go for office expenses and salaries." "Whose salaries?" asked Roger. "I don't want any and I need only a few day laborers." "You don't get me." Eaton was patient. "I'm speaking of the Solar Company's Chicago office." "Shucks! We don't want an office in Chicago. What we want is a plant in Arizona."
