class struggle bases itself squarely upon it, and boldly and correctly sets out the socialist principle "that the working class and the employing class have nothing in common...."[209] The second I. W. W. convention met on September 17, 1906, with ninety-three delegates. The sessions continued for sixteen days. It had been predicted at the first convention that the Industrial Workers of the World would within a year be one hundred thousand strong. This forecast was, according to Secretary Trautmann's report to the second convention, very much too sanguine. This report indicated that there were some sixty thousand members (including 27,000 in the Western Federation of Miners) at the opening of the second convention. The following tabulation of the growth of the membership during the first year is arranged from the data given in Mr. Trautmann's report: I. W. W. MEMBERSHIP--FIRST YEAR[210] _Unions_ _Transportation_ _Metal_ _Total_ _directly_ _Dept._ _Dept._ _Membership_ _Date_ _attached_ 1905 Aug. 1 1,900 Sept. 1 4,247[211] Oct. 1 1,000 840 5,078 Nov. 1 840 5,482 Dec. 1 840 7,971 1906 Jan. 1 840 8,200 Feb. 1 7,817 Mar. 1 9,275 1,500 10,775 Apr. 1 10,288 3,000 13,228 May 1 13,520 195 3,000 16,715 June 1 21,000 July 1 22,500 Aug. 1 45,000 Sept. 1 60,000 The data, it will be noticed, is very fragmentary in regard to the growth of the various departments, and even the figures representing total membership can be considered by no means conservative. Mr. St. John, until recently Secretary-Treasurer of the organization, wrote "that the Second Annual Convention reports claim 60,000 members, but the books of the organization did not justify any such claims; in fact, the average _paid-up_ membership _with the W. F. of M._ for the first year of the organization was 14,000 members in round numbers."[212]
