Pursuant to a call issued by the Amalgamated Building Trades' Council of Chicago, a convention of delegates from building trades organizations of the country met in this city on Tuesday June 28, and in a three days' convention perfected a national organization with the objects as set forth in the preceding paragraph. Notwithstanding the short notice given, there were in the convention delegates from fourteen of the principal cities of the union, representing one-half million journeymen builders. The result is that the National Building Trades' Council of the United States is now an established fact, working under a temporary constitution, copies of which accompany this circular. We submit the action of the convention and the constitution to the building trades organizations of the United States, and ask their prompt and active support of the movement. The convention, after due deliberation, decided, as it was hardly more than preliminary, that the first regular session of the national council should be held as soon as possible; that the delay in bringing all the building organizations under one head should not be greater than the time necessary to disseminate the work of the convention and to allow sufficient time for the many organizations to act; it was therefore decided to name the third Tuesday in September, 1887, as the date for holding such session. The place selected for the next convention is Chicago. All organizations receiving a copy of this circular are urged to take action in accordance with the constitution, and at once to open correspondence with the general secretary of the council, who will furnish information to those desiring it. Brothers, in conclusion, we urge you to give your support at once to this movement and to aid in perfecting an organization which may be made a power second to nothing of its character in the world, as its field is as broad as this great land, and its opportunities as limitless as humanity. On the last day the following resolutions were adopted: _Resolved_, That, in the event that the committee of the Chicago bricklayers do not succeed in making a satisfactory settlement with the Master Builders' association, the council declare the Chicago difficulty a national cause and appoint a committee on arbitration to meet the bosses, the power to appoint such committee resting in the hands of the president, in session or after adjournment. _Resolved_, That, in the event of failure of such committee to settle satisfactorily the trouble, the president, with the concurrence of the executive board, make an appeal to the building trades organizations of the United States, asking support--financial and moral--for the building-trades organizations of Chicago.
