July 18.—Since the last note in my diary we have been pursuing our usual course. The tenor of our way is singularly rough and uneven, marked by the sound of cannon, the marching of troops, and all the paraphernalia of grim-visaged war; but we still visit our friends and relatives, and have our pleasant social and family meetings, as though we were at peace with all the world. The theme of every tongue is our army in Maryland. What is it doing? What will be the result of the venture? The last accounts are from the Washington papers. Early, they say, is before Washington, throwing in shells, having cut the railroads and burnt the bridges. We are of course all anxiety, and rumour is busier than ever. The army, it is said, has driven innumerable horses, beeves, etc., into Virginia. I trust so; it is surmised that to supply the commissariat is the chief object of the trip. Grant still before Petersburg, sending transports, etc., with troops to defend Washington.
