The West.
--The letter from an esteemed correspondent in Tennessee on the condition of our military affairs in the West is anticipated by the appointment of the man for that division of the Confederacy and indeed for the times. General A. S. Johnston has, we understand, been appointed to direct our military operations in the Mississippi Valley, and will proceed promptly to his post. With his able Generals he will soon arrange his plans and put our affairs in the best condition.
