Since the reports forwarded this morning in regard to the disposition of the enemy's forces, their preparations to retreat, &c., the following was received, at 4 p. m. to-day, from Major-General Reynolds:

Three citizen scouts, just in from the other side of the river, report some guns-number not known-at foot of Lookout Mountain; a cavalry picket opposite Rankin's Ferry Ford; two or three companies of cavalry at Taylor's Store, and one regiment of infantry at Trenton, Adeserter just in confirms the above. Says he saw them loading machinery from Webster's foundry on cars, on Monday. They said it was going to Adairsville. Colonel King proposes bringing over their cavalry pickets to-night.

Very respectfully, your obedient servant,

GEO. H. THOMAS,

Major-General, U. S. Volunteers, Commanding.
