“Philadelphia, June 5, 1779.

“My business is almost completed, and to my mind.  I now wait for nothing but the money which the Medical Committee recommended I should be furnished with; I expect to receive it the beginning of next week, when I shall set out immediately.  Mr. Samuel Adams travels with me; indeed, the time seems tedious until get away.  Give my duty to our parents, love to the children, &c., and believe me to be, with the sincerest affection, my dearest Polly,

“Ever yours.”

Philadelphia, June 9, 1779.

“MY DEAR POLLY,

“Another post has arrived, and no letter from Boston.  It is now a month, and near five weeks, since I have heard from you.  If I thought you had neglected writing, it would make me very unhappy; but, from your usual goodness, I cannot think that is the case, but am confident your letters must have miscarried.  I have wanted nothing but hearing from you to make my time here perfectly agreeable.  I have been received with the greatest politeness and friendship, and every attention paid to me, by men I most esteem, I could wish for; at the same time my business has gone perfectly to my mind.  I have leave to reside in Boston for the future, and shall be under no necessity of attending the camp, nor be obliged to visit Philadelphia oftener than once a year.  I am to have a mode of settling my accounts pointed out to me, that will be easy, simple, and much to my mind.  I now wait for nothing but money to begin my journey.  The Treasury Board this morning passed a resolve recommending it to Congress to furnish me with $150,000.  I expect to receive the warrant to-morrow, and as soon as I get the money shall set out, which I expect will be about next Monday, until which time I am engaged for almost every day.  I dine this day with Mr. Adams; tomorrow with Dr. Shippen, in company with the New England delegation; Thursday and Friday I expect to spend with Dr. Craigie in visiting Red Bank, Mud Island, and other principal scenes of action while the enemy were here.  We have an account that the enemy are in motion up the North River; but of them you will hear sooner than I can inform you.  General Lincoln has actually defeated the enemy in Carolina, and is like to take them all prisoners.  The express is on the road, and expected in town to-morrow, when there will be great rejoicing.”
