Art. I., Sec. 2.--And shall be composed of thirteen international industrial divisions subdivided into industrial unions of closely related industries in the appropriate organizations for representation in the departmental administration. The subdivisions, international and national industrial unions, shall have complete industrial autonomy in their respective internal affairs; provided, the General Executive Board shall have power to control these industrial unions in matters concerning the interests of the general welfare.[155] The list of specifically divided industries was later replaced in the constitution, but in a very much improved form. Wm. E. Trautmann has worked this up even further, and in 1911 published a still more improved outline in which the number of departments is reduced to six.[156] The constitutional convention also made provision for other and subordinate bodies, _i. e._, industrial councils, which might be formed. These were to comprise seven or more local unions in two or more industries and the local industrial union. These local unions were the smallest units of organization then provided for, except that when isolated individuals applied for membership in a locality where no local union existed, such persons were admitted into the organization as "individual" members directly attached to the general organization. The same principle applied throughout. In case, then, there were not a sufficient number[157] of locals in any one industry to form an industrial department, the local was directly responsible to the general organization. Then, as now, the great majority of local unions were chartered directly by the general organization. At the close of the first convention the Western Federation of Miners became the "Mining Department" of the I. W. W.; the Metal Workers became the "Metal Department"; and the United Brotherhood of Railway Employees, the "Transportation Department." All local unions are industrial in character, _i. e._, each one makes the shop its unit and comprises all the crafts engaged in and around the shop. The mucker in the mine must belong to the same union as the man who runs the drill. The idea is to get into the same union all those workers who are coöperating for the production of a given class of products. The officers provided for were: a General President, a General Secretary-Treasurer, and a General Executive Board composed of these two officers and the Presidents of the International Industrial Division.[158] The constitutional committee recommended
