Though this series contains pension/veteran letters for the periods December 1884 and March 1887, the majority of the Adjutant General's correspondence dealing with pensions may be found in Volunteer Service Letters, Series 1120. Beginning in 1867, the incoming correspondence corresponds to the outgoing correspondence contained in the Adjutant General's Letterbooks, Series 1121. After 1880, the Adjutant General National Guard Letterbooks, Series 1122, have that relationship to Series 1927. As both sets of letterbooks are alphabetically indexed they should be consulted as indexes to incoming correspondence.
