The gentleman understood that this unfortunate happening was likely to cost them dearly, since the inventor, knowing the value of his patent, would be likely to hold out for a much larger sum.

“Now, if you will let me see some papers to prove your identity, Mr. Nelson, we will talk shop with you; and I might as well confess in the beginning that if you are inclined to treat us fairly we can come to terms with you; but please consider that only one trial has been given to your stabilizer; and it may, after all, be of less value than appears at this moment.”

Hiram needed no second invitation to get busy. He immediately unloaded a mass of proof upon them to show he was all he claimed, and that he also had the papers connected with his patent.

“I am satisfied, so far as that goes,” announced the gentleman, as though desirous of arriving at the most important part of the whole proceedings as soon as possible. “Now will you please state the very lowest cash price you will accept to turn the patent over to this company?”

“Five thousand dollars, sir!” replied Hiram promptly.

Rob was watching the other’s face. He saw something there that told him Hiram had at least not exceeded the amount which would have been reckoned a price limit for the invention. Mr. Curley, however, was too good a business man to show any eagerness in the transaction, though there was certainly a gleam of satisfaction in his eyes as he seemed to consider the offer.

“I am going to be frank with you, Mr. Nelson,” he remarked, presently. “The sum you mention, although somewhat larger than we had contemplated paying for an invention the value of which has still to be fully proved, is within the amount we could afford to risk in the hopes of getting a really dependable stabilizer. Now, if we agree to do business with you, would you consent to sign a paper here and now to turn over your patent right entirely to us on the receipt of the sum you mention, five thousand dollars?”

Hiram was holding his own remarkably well. He refused to show any signs of being overwhelmed by his great good fortune, and seemed to be capable of displaying his customary shrewd Yankee bargaining qualities.

“I’ll agree to do it, Mr. Curley,” he said deliberately, “if your company also makes the bargain so it can’t be broken. It mustn’t bind only me. Pay a certain sum in hand, and agree to give me the balance to-morrow, and I’ll sign the paper you speak of, handing over the patent rights transferred to you when the balance is put in my hands.”

“That’s strictly business acumen, Mr. Nelson,” said the gentleman, now smiling broadly, for there was no longer any danger of a backdown, and the wonderful little invention could not be taken away from them by some rival and wealthy company; “and with your permission, then, here is an agreement, in duplicate, with the amount left blank, which I will fill in according to your proposition; and if everything is agreeable, we will both sign it in proper form.”
