VALLEY MOUNTAIN, September 1, 1861.
We have had a great deal of sickness among the soldiers, and those now on the sick list would form an army. The measles is still among them, but I hope is dying out. The constant cold rains, mud, etc., with no shelter or tents, have aggravated it. All these drawbacks, with impassable roads, have paralyzed our efforts.
