"NEUES PALAIS, Dec. 31.--To the President of the United States: Aghast at the terrible news of the catastrophe that has befallen the citizens of Chicago the empress and myself wish to convey to you how deeply we feel for the American people who have been so cruelly visited in this week of joy. Please convey expression of our sincerest sympathy to the city of Chicago. Many thanks for your kind letter. In coming years may Providence shield you and America from harm and such accidents. "WILHELM I. R." Within a few days there was abundant evidence that profound sympathy had given place, in all the large cities of the world, to practical endeavors to avert like calamities. NEW YORK THEATERS AND SCHOOLS. As his first official act, Nicholas J. Hayes, who on New Year's became fire commissioner of New York, ordered an investigation of all the theaters of that city. He declared that he intended to ascertain whether the New York playhouses were so constructed and equipped as to safeguard human life in case of fire or panic. "The protection of human life is the first and most important duty of the fire commissioner," said Mr. Hayes. "In this work no one shall hinder me from doing my full duty." In each battalion district where a theater was located the new fire commissioner designated a competent assistant foreman as theater inspector and provided for weekly inspection of theaters. These inspectors were under the supervision of a general theater inspector. One of the tests at once applied by Commissioner Hayes was to have the inspector pour gasoline on the asbestos curtain and then apply fire. Several houses were at once closed, as the curtains failed to stand the test. City Superintendent of Schools Maxwell, of New York, also issued special fire instructions to the district superintendents and principals of schools, whom he directed to perfect fire drills and the rapid dismissal of school children under their care. CRUSADE IN PITTSBURG. The Pittsburg department of public safety immediately began a crusade against the violation of the ordinances regarding theater construction and equipment. Managers were compelled to arrange their fire escapes, curtains and apparatus so that everything worked with facility. At the Nixon theater, at the close of a performance, the people were rapidly dismissed after a fire alarm, and ushered out into the alley exits and down fire escapes in two and one-half minutes. Other theaters were put through similar drills. WASHINGTON THEATER OWNERS ARRESTED. Warrants were issued for the arrest of the proprietors of three of the seven Washington theaters. Failure to comply with building regulations in making improvements resulted in the withholding of the license of one theater. The two other proprietors were arrested for failure to provide proper exit lights, fire escapes and stage stairways. MASSACHUSETTS THEATERS INVESTIGATED.
