The enemy’s account of our loss in the battle before Atlanta is exaggerated greatly. Sherman’s army is doomed, I think.

Seven p.m. No rain here, but my family were drenched in a hard shower at Hanover Junction, and what was worse, they got no blackberries, the hot sun having dried the sap in the bushes.

August 3d.—Cloudy, but no rain.

The press dispatches last night assert that still another raiding party, besides Stoneman’s, was dispersed or captured.

It is rumored to-day that Beauregard has sprung a mine under Grant’s fortifications. This may be so. Later. It was not so.

August 4th.—Clear and hot.

All quiet at Petersburg. President Lincoln was at Fortress Monroe on Sunday last, after the explosion and its failure.
