This is the first case of decided and extreme summer hear. I should not have gone to town with Mr. Brooks had I not supposed it probable that some of the Tenants might call to settle. My expectation was realized and I found I had determined wisely. Miss Oliver called. I was engaged in my Accounts much of my time. It was very advisable to keep as cool as possible. Returned to Medford. Afternoon passed as quietly as possible. Read some German and some of Ovid. Evening, it grew more sultry so that we could do nothing and afterwards, the Night was one of the hottest that I ever passed in this Climate. The same dead calm which is so often felt in Washington and leaves a man more tired in the morning than he was the night before.
