NOTES TO TABLE A.
Here are assembled most of the available figures relating to I. W. W. membership and fluctuations in membership during the period 1905-1917. The figures are fragmentary and, for the most part, approximations; those in columns 1, 6, 7 and 11 being especially rough and fragmentary. For example, it will be observed, in comparing columns 7 and 9 with column 11 for the year 1914, that there must have been at least 1784 defunct locals at that time instead of 681 as the record shows.
The figures in italics were furnished by the secretary-treasurers, Vincent St. John for the Chicago I. W. W., and Hermann Richter for the Detroit I. W. W.
