Saturday, June 4th, the Illinois State Association of Architects met. In calling the meeting to order President D. Adler read a letter from the executive committee of the Builders' and Traders' exchange thanking the Association for the stand it had taken upon the labor troubles. He said that those present knew the demoralized condition of the building trades and the low character that they were drifting to in regard to the workmanship of mechanics engaged therein. It was becoming almost impossible to replace good men, because the trades-unions arbitrarily prevented the education of a sufficient number of apprentices to replace the good and competent mechanics, who appeared to be rapidly dying out. The difficulty was staring them in the face that soon they would not be able to secure competent mechanical skill at all. It was the architects' duty to assert the right of every American citizen to work at any trade he pleased, without interference from the walking delegate. It was the architects' duty to assist every young man who desired to learn a trade. There was more at stake in the contest than their own immediate interest as architects--more than the mere stoppage of work. The architects should strengthen the hands of those who were battling for the freedom of American citizens. Mr. John W. Root offered the following resolution, which was adopted: _Resolved_, That the Illinois State Association of Architects heartily indorse the general principles set forth in the recently published "platform and code of principles" adopted by the Builders' association and the Real Estate board of Chicago, and that we will use our utmost endeavors to see that these principles prevail in all building operations in Chicago. PROTECTION GUARANTEED. The committee of safety of the Central Council of Building Interests met June 4th and issued the following document: The Central Council of the Building Interests of Chicago having appointed, among other committees, a committee of safety, whose duty it is to "see that ample protection to all is afforded against unlawful interference," the committee desires to announce to all concerned in the building interests of the city that they are prepared to follow up and prosecute all offenders unlawfully interfering with or intimidating any workman or employer in the legitimate performance of his business. This announcement is hastened by the publication in the morning papers of an unlawful and unprovoked attack upon peaceable workmen at a job at the corner of Harrison street and Western avenue on Friday, June 3d. The committee will promptly investigate any such case when reported to Secretary Schoenthaler at the Builders' and Traders' exchange, where the committee will be in daily session at 2 o'clock P. M. MASS MEETING OF CARPENTERS.
