Tuesday, 16th—We have had several days of very warm weather which became very hot yesterday, but today there is a high wind accompanied by thunder. The Eleventh Iowa signed the payroll today for two months’ pay. Cannon have been roaring all day and the place still holds out. General Grant still feels confident that he can take the place, and the army is in fine spirits. Only a few tents are used now, and they are only for the sick and wounded.
