I have made free to trouble Your Excellency with the following Letter, on which Lord Howe & the Navy Office have Corresponded with Me, but as I am under a disagreable Arrest in Goal for a Debt of 21. for which Lord Howe will not agree to pay one farthing, however much My plan would save Government, therefore think I am free to offer my Service to any whom I please and if agreable may shew it to the French Ambassador below is the Copy of my Letter sent to the Admiralty and a Letter from a private Gentleman Manufacturer to Me by which You will learn He has some Thoughts of encouraging Me. Sr. Your Answer  the above will be esteem’d a great Favour / By Your Excellency’s most obt. hbe Servt.
After many Experiments I have found by one Way of dressing Sailcloth after it is wove, it will last one third longer & lose 1/5 or 1/6 of its Weight, & be 1/5 easier wrought, at Sea, & gain 1/5 better Colour, This would if adopted far exceed the Russian German Dutch & Patten Sailcloths in resisting Milldewn as the Cause is remov’d & a preservative infused theirin, if this is worth Your Notice give Me Your Answer & Oblige / You’s &c.
P.S. The great Attachment I have had for the American Cause & for which I have suffer’d for in my Native & I may say Arbitrary Country. & to which I am again invited—Well knowing the Usefulness of my Knowledge & Abilitys if enabled to go to America I should chuse it & their resign my Breath amongst so brave a People who have withstood such a Storm of Tyranny & Oppression—& as I know the course Linnen Manufacture from the Seed to the Needle with all its various Process, & Utensils I could direct them all personally without any Models as I perfectly understand it
