Sir's.—

Your esteemed favours of the 21^st December¹ P^r: M^r. Deane,² 12^th February³ P^r. Cap^t. Senneville,⁴ & 17^th of the same Month P^r. Cap^t. Courter,⁵ we had the Honor to receive.—

Agreeable to your request, we have furnished Cap^t Courter, with every necessary, for his Journey to Congress, On which he set out the 7^th. Instant, being the second day after his arrival with us. The Money & other Articles advanced Cap^t Senneville, We have by advice of the Council charged to the United States.—

Every Mark of Distinction, Government could shew, & all the assistance this Board could give, Cap^t Senneville has received, we flatter ourselves, to his entire satisfaction, & happy shall we esteem ourselves, if by any Exertions on our part, we may be in the smallest Degree, instrumental in Strengthening, & Cementing, the Union between the Court of France; & the Independent States of America.—

This Important, & Fortunate Event, has already produced the most Salutary effects: It has had a tendency to fix the Wavering, confirm the Doubtfull; & diffuse Spirit & Animation through the whole. Our Moneys, those Sinews of War, have acquir'd new credit, & value; firmness, resolution, & unanimity; pervade the Thirteen United States. 

But while we devoutly adore, that Almighty Being; to whose interpositions, in our favour, we are to attribute our present happy Situation; We wish not to be forgetfull of those WORTHIES, by whose unremitted assiduity's, this most arduous Business, has been thus gloriously accomplish^d. 

May every Happiness, Temporal, & Eternal, attend your Excellencies; and may Succeeding Generations as they Riseup, call you blessed.—We have the Honor to be with profound respect's [&c.]
