--------------------------------------------------------------------------------- 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. FOOTNOTES: [A] Average membership 1905-1906. Computed from record of receipts for the General Defense Fund (_Proceedings Second Convention_, p. 586.) [B] Approximate. W. D. Haywood before U. S. Commission on Industrial Relations, Washington, D. C., May 12, 1915. (_Final Report and Testimony_, vol. xi, p. 10581.) [C] _Weekly People_, Sept. 27, 1913; also testimony of Rudolph Katz before U. S. Commission on Industrial Relations (_Final Report and Testimony_, vol. iii, 2485). [D] Only 2000 were "in good standing." [E] No data available. [F] St. John, _The I. W. W.--Its History, Structure and Methods_ (1917 ed.), p. 23. [G] The figures in column 3 are from Professor Geo. E. Barnett, "Membership of American Trade Unions," _Quarterly Journal of Economics_, vol. xxx, p. 846 (August, 1916). His figures come, apparently, from I. W. W. headquarters in Chicago, but they do not agree entirely with those furnished the author by Secretary St. John. [H] In this and some of the following columns more than one figure has been included in years for which varying estimates were found. The sources for column 4 are as follows: _Proceedings 2nd I. W. W. Convention_, p. 60; Report of the I. W. W. to the Stuttgart International Socialist Congress, _Industrial Union Bulletin_, Aug. 10, 1907, p. 4; _Bulletin New York State Department of Labor_, no. 67 ("International trade union statistics"), p. 3; Louis Levine, "The development of syndicalism in America," _Political Science Quarterly_, vol. xxviii, p. 478 (Sept., 1913); Vincent St. John's testimony before U. S. Commission on Industrial Relations (_Final Report and Testimony_, vol. ii, p. 1456; _Weekly People_, Dec. 9. 1916, p. 1, col. 3).
