The first number in each set is the number of interventions; the second is the number of troops involved. No attempt is made to distinguish between troops actually deployed at the site of the incident and troops that were called up and placed at a distance on stand-by alert.
* National Guard data from 1928-30 consisted of a simple listing of interventions without figures for the number of troops involved.
** Annual Report of the Chief of the Militia Bureau for fiscal years 1931 and 1932 have no listings of the activities of the National Guard during those years, and I can find no published record of them elsewhere.

2. Abbreviations as in Table I.
3. Sources: Annual Report of the Chief of the Militia Bureau for each year from 1921 to 1927. Prior to 1921 these reports did not list interventions. Where names of military units were given rather than number of troops, the troop numbers were calculated from figures given that year for average troop strength by state and unit. Figures for federal intervention in labor disputes obtained from Reichley (1939, p. 201). Figures for federal intervention against banditry are from Parker (1970, p. 52).
4. Sources: Annual Report of the Chief of the Militia Bureau for 1928,1929, and 1930. Interventions were listed, but without the number of troops involved. No federal troop interventions took place according to Reichley (1939).
5. No data are available for these years for National Guard interventions. The one federal intervention was suppression of the Bonus Army of the unemployed, for which troop figures are taken from American Military History (1969), p. 413.
6. Sources: Congressional Record, 74th Congress, II Session, Vol. 80, Part 2, pp. 2069-2081, Jan.-Feb. 1936. There is also mention in American Military History (1969, p. 413) of a federal intervention in 1934 when the Air Corps took over carrying airmail in a dispute with the airline companies. The number of troops involved is taken from the New York Times, 13 Feb. 1936.
