I am apprehensive I have left the draft of the hemp break amongst some papers I left in charge of my Son at the city of Washington, I hunted diligently for it here, but contrary to my expectation cannot find it, however, I can draw or explain the model from memory So as to make you perfectly understand the principal on which it works, I will Send it to you on Saturday
you will See by the scrap enclosd Something of the principal on which it works he scratched it off withe the pen & from that took his draft
