The Correspondence series is composed of letters to and from Garrison in his capacity of Secretary of War with government and military officials and concerned citizens. The correspondence includes discussions of military policy and world events, as well as business pleasantries such as invitations, letters of introduction, letters of appreciation for materials received, requests for photographs and statements, and travel itineraries. The majority of the correspondence is concerned with World War I, including military preparedness, legislation effecting the military, training and cadet candidacy at West Point, enlistments and retirements, awards and medical care for military personnel, and aiding American citizens who were in Europe. The correspondence also discusses other issues that fell under the auspices of the War Department, including addressing violence along the border with Mexico during a civil war, the Panama Canal, the Philippines, a strike in Colorado, and water issues.

This series contains Morris's personal correspondence, accumulated over a lifetime. Most of his correspondence dealing with the clubs and organizations he participated in is filed with other material of those corporate bodies in Series 9, Papers of Others. Correspondence dealing with specific writings will be found in Series 1, Writings.
