A new invention had appeared, called the Gwynne & Sawyer static-pressure engine, that was bound to revolutionize all applications of power. It was, he told me, attracting great attention in engineering circles, and there had been a hot discussion over its theoretical principles, but its advocates had successfully vanquished all their antagonists and now the invention was established on a perfectly sound scientific basis. If I would give him a receipt in full for the money that he owed me and put another $100 into this enterprise, he was in a position to secure for me a number of rights to use the machine. He kindly offered to introduce me to Mr. Sawyer. Mr. Gwynne was unfortunately absent from home at the time. (I learned afterwards that he was in jail.) Mr. Sawyer received me most graciously. I think he had been told by Mr. Searle about how much taffy I might be expected to swallow, but he must have ventured far beyond his instructions. He told me that he was delighted to make my acquaintance; he had frequently heard of me through our mutual friend, Mr. Searle, and of my triumphs at the bar, and had come to feel a great admiration for me, and was proud to show this great invention to a man so eminently capable of appreciating it. He told me that the invention was a practical method of utilizing that wonderful power known as centrifugal force. This force could be obtained in any amount. In fact, it was the force that kept the universe in motion. It had lain unutilized for so long a time because engineers had never been able to apply it practically. This difficulty had been completely overcome in this great invention, and this wonderful power was now to be made available for the world. He gave me quite an oration on the subject, saying, “We do not antagonize the forces of nature, we utilize them and apply them to beneficial purposes; consequently all nature co-operates with us,” and more to the same effect. He was able to show me a working model of this great invention; was very sorry that he could not put it in motion for me that day, as it happened to be a little out of order; but I would be able to see the principle of its operation very distinctly. I was flattered into believing that I saw the principle, with the result that Mr. Sawyer saw the principal, and with the further result that after that I never saw or heard of either principal or interest. Our mutual friend, Mr. Searle, also disappeared. This was my first lesson in mechanics, given to me by a master of his art. I am not sure, on the whole, but that in one way and another it has been worth the trifle it cost me.
