Notice having been received by the president of the Builders' and Traders' exchange that the officers of the National Association of Builders were to be in Chicago, the board of directors of the exchange met and appointed the following committee to receive them: George Tapper, Joseph Downey, George II. Fox, James John, M. Benner, Charles A. Moses, William E. Frost, F. C. Schoenthaler, and James C. Beeks. The officials were met and were fully informed by the committee of what had occurred in Chicago from the inception of the labor trouble which had paralyzed the building trades, and were furnished with a copy of the platform of principles adopted by the Conference committee of the building trades. The situation was informally discussed by the officers of the National Association and the reception committee, in order to put the visitors in a position to fully understand the ground upon which action had been taken. They were apprised of the demands which had been made from time to time for years, and of the fact that these demands had been generally acceded to until they had become almost unbearable, and that the builders of Chicago thought the time had arrived when decisive action should be taken in order to insure a permanent settlement of the troubles which had disrupted the employers and the employes. Referring to the situation William H. Sayward said it was not alone Chicago builders who were affected by the movement, but the whole country was interested in it. The builders of Chicago and those of other cities could see the benefits which were expected to be derived from a national association. Before that, when there had been a strike of any magnitude in any city, the builders engaged in the complications received not even a word of sympathy from their associates in other parts of the country. In their troubles the Chicago builders had received messages of sympathy and approval from almost every part of the country, because all felt and had a common interest in the questions at issue. A LITTLE SYMPATHY. The Central Labor union men met Sunday, May 22d, and compassed the situation by the passage of the following sympathetic resolution: _Resolved_, That the present lockout of the bosses is in every way unjustified; that the Central Labor union declares that it is a conspiracy against the rights of the working people, and extends to the locked out workmen hearty sympathy and financial as well as moral aid. ANOTHER THREAT. The Trade and Labor assembly met the same day and threatened to prosecute the Master Masons for "conspiracy" and agreed that they should be boycotted. The proposition to prosecute the bosses did not materialize, as wiser counsel prevailed, and showed that there was no foundation upon which to build the charge. OVER THE WIRE. Telegrams were received as follows: BOSTON, Mass., May 19, 1887.
