on the spot. In a letter addressed to his father, dated November 27, 1778, he says,—
* * * * *
"Public business calls me to Philadelphia; but the state of your health, and my own, which is much impaired, determine me to visit Boston first. I expect a visit from the Marquis La Fayette next week, on his way to Boston, and shall set out with him."
* * * * *
May 11th, 1779, he writes,—
"To-morrow all the gentlemen of the department at this post [Danbury] dine with me, and the next morning I begin my journey to Head-Quarters. I mean to take Newark in my way.
"General Silliman was taken prisoner last week, and carried to Long Island."

In the two following letters to his wife he speaks of this visit.
"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."

The following letter describes one of Dr. Foster's frequent journeys on business of his department.
"Windsor, October 7, 1779.
"MY DEAR POLLY,
"As I am waiting for Mr. De Lamater to come up, I will endeavor to give you an account of our journey. The evening we left Boston Dr. Warren rode with us as far as Jamaica Plains; after he left us we proceeded to Dedham, where we arrived about dark, and were exceedingly well entertained: we had a brace of partridges for supper. Colonel Trumbull spent the evening with us. The next morning we proceeded nine miles to Heading's to breakfast, and from thence seven miles to Mann's, where we fed our horses, and dined at Daggett's, nine miles further; that afternoon we arrived at Providence, and put up at our old friend Olney's. The next day we dined with Adams and Townshend at their quarters; the General honored us with his company; the same evening supped with the General. Sunday, dined with the General, in company with some of the principal ladies of the place; here I also saw your old acquaintance, General Stark; he drank tea at my quarters one afternoon, and inquired after you. Having finished my business much to my mind, I continued my journey on Monday morning; the General, Colonel Armstrong, and Dr. Brown were so polite as to ride out four miles with us. After they left us, we proceeded to Angell's, twelve miles from Providence, where we dined,—not on the fat of the land. After dinner we rode to Dorrence's, an Irishman, but beyond all comparison the best house on the road; here we were exceedingly well entertained, and, as it looked like a storm, intended staying there, but, it growing lighter towards noon, we set out, but had not rode far before the rain came on; however, as we had begun, we determined to go through with it, and rode a very uncomfortable ten miles to Canterbury, where we dined, poorly enough, at one Backus's. Not liking our quarters, we proceeded, notwithstanding the rain, to Windham, eight miles further, where we were well entertained at one Cary's. As the storm looked likely to continue, and I was so near Windsor, I was determined, if I must lie by for it, to lie by in a place where I could do some business. I accordingly proceeded fifteen miles in the forenoon to Andover, where I dined at one White's, and fifteen miles in the afternoon to Bissell's at East Windsor, where I lodged. I was thoroughly soaked, but do not find that I have got any cold. Indeed, I find my health considerably better than when I left Boston. This morning it has cleared off very pleasant, and I crossed from East Windsor to this place. I have just returned from visiting Mr. Hooker's and Dr. Johonnot's stores. I find everything in such excellent order as to do credit to the department. Mr. De Lamater is not yet come up; as soon as he arrives we shall visit Springfield. I shall not close this letter until I meet the post; if anything worth notice occurs, I shall mention it. Adieu, my love.
"October 8.—Mr. De Lamater arrived last night. Altho' it is very raw and uncomfortable, I shall proceed immediately after dinner to Springfield. We have certain advice that the Count D'Estaing has been at Georgia, and taken all the British ships there; it is reported, and believed by many, that he is arrived off Long Island. You see, my dear Polly, I have set you the example of a very long letter. I hope, as you have leisure enough, you will follow it, as nothing can give me greater pleasure."

"Fishkill, October 21, 1779.
"MY DEAR POLLY,
"I returned from Head-Quarters this forenoon. We went down yesterday morning, and dined with General Heath, who was so good as to lend us his barge to carry us to Head-Quarters. His Excellency received us as I could wish. He invited us to dine with him this day. Upon my excusing myself, as being in haste to finish my journey, he accepted the excuse, and invited us to breakfast with him, which we did. We returned last night to Robinson's house, and slept with our friend Eustis. General Heath favored us again with his barge to carry us to Head-Quarters, and after breakfast his Excellency ordered his own to convey us to our horses, which we had ordered four or five miles up the river. One principal reason of my declining the General's invitation to dinner was my impatience to return to Fishkill, that I might receive a letter from you. Judge, then, what was my disappointment to find the post arrived and no letter. I shall cross the North River to-morrow morning to proceed on my journey to Philadelphia. If the nature of the service will allow it, General Heath and his suit propose returning with me to spend the winter in Boston. Eustis desires you would look out some suitable object of his attentions, while in Boston. He pretends it is only with a view to keep him alert and properly attentive to the ladies in general; but I suspect he designs to become the domestic man."
