Head Quarters Boston April 8th 1777
Sir
The Honble Thomas Cushing Esqr has Just Informed me, that the Two Continental Frigates which have been fitting out of this Port and are now ready for the Sea were to have had their Powder from This State (Massachusetts) But that upon a Proof of the Powder it appears Bad I think it is of great Importance that the Ships should be at Sea as Soon as Possible, as many advantages may accrue from it, If you Can therefore furnish the Powder necessary for the Two Frigates from that lately arrived, and now under your Care (which I suppose will be nine or Ten Tons) Consistant with your Instructions I think it will greatly Promote the Publick Service, and I would most Heartily recommend it, I am Sir [&c.]
