Rain and clouds. At home all day. Evening at the Mansion.

The rain fell heavily in the morning with warm weather which cooled off at night with a northeaster. I was pretty steadily engaged all day upon the papers which I proposed to draw up for the Courier in answer to the Philadelphia exposition. They contain a very brief statement which I will expand for Mr. Hunt in case he wants it. But the labour of the thing is not trifling, particularly when taken in connexion with my other work. Evening for an hour at my father’s. Nothing new.
