Warm day. At home as usual. Afternoon ride to Brookline and evening at Mansion.

I devoted most of my morning to the prosecution of my Lecture upon credit which did not however get on so fast as heretofore. There is a necessity for cautious investigation.

In the Afternoon, I started with my Wife to return the visit of Mr. and Mrs. Rogers at Brookline. The distance is very considerable and when we arrived there we found nobody at home, so we had our labour for our pains. Returning we passed by Jamaica Pond and the beautiful country around it. Evening for an hour at the house below.
