Honoured Sir

It is with no small Concern that I acquaint you, that your improved Plan of the Horizontal Windmill is little, if anything, found on trial, superior to the Plans already laid down and like them, does not exceed the power of a strong Mule. Therefore, tho’ it may grind Corn or raise water, it never can overcome the resistance of Canes, so as to do any essential Service. Next to that Service is the knowledge of its real powers, which I, as proposed, beg you to lay before that Philosophical Society, which has the happiness of having so worthy a President.

With my most grateful Acknowledgment of your Liberality and Candour and the most perfect Respect and Esteem I remain Your Excellency’s most oblig’d, most humble servant
