Baltimore March 2d 1809
May it please your Excellency,
As I have the honour to inform you of the great Discovery I have Made, And which has so long been a Mystery to the known world, when the Mechanics of all Europe and other parts of the whole world have been gathered together together, to Study it and never Yet made a discovery, and as I think I have been endowed with the good luck or fortune of finding it out which has been so far beyond the Ideas—and Conception of all former ages So I hope it will be of great Use to all Mechanical Manufacturers hereafter, And I also Understand that there always was a great reward offered for them that would—make the discovery which was always of so much importance. It is called and I believe always was called the Perpetual Motion, which I have the pleasure to enform You of as I thought You—the most proper. I would thank you if you would lay this before the House. For I hope I will not have my labour for my pains. But a handsome Reward, I hope if you receive this letter you will send me an Answer as soon as possible and let me have your Opinion on the Subject. I am Sir respectively your humble Servant
