CHICAGO, July 3.—The authors’ strike is assuming alarming dimensions and is almost beyond control by the police. The Mayor is strongly urged to ask for assistance from the militia, but the strikers profess to have no fear of his doing so. They say that he was once an author himself, and is in sympathy with them. He wrote “The Beautiful Snow.” In the mean time a mob of strikers numbering not fewer than one thousand men, women and children, headed by such determined labor leaders as Percival Pollard and Hamlin Garland, are parading the streets and defying the authorities. A striker named Opie Reed, arrested yesterday for complicity in the assassination of Mr. Stone, of the publishing firm of Stone & Kimball, was released by this mob from the officers that had him in custody. Mr. Pollard publishes a letter in the _Herald_ this morning saying that Mr. Stone was assassinated by an emissary of the Publishers’ Protective League to create public sympathy, and strongly hints that the assassin is the head of the house of McClurg & Co. —————— NEW YORK, July 4.—All arrangements for celebrating the birthday of American independence are “off.” The city is fearfully excited, and scenes of violence occur hourly. Macmillan & Co.’s establishment was burned last night, and four lives were lost in the flames. The loss of property is variously estimated. All the publishing houses are guarded by the militia, and it is said that Government troops will land this afternoon to protect the United States mails carrying the manuscripts of strike-breaking authors, in transit to publishers. The destruction of the Astor Library and the Cooper Union and the closing of all the book-stores that escaped demolition in yesterday’s rioting have caused sharp public distress. No similar book-famine has ever been known in this city. Novel-readers particularly, their needs being so imperative, are suffering severely, and unless relieved soon will leave the metropolis. While beating a noisy person named E. W. Townsend last night, one Richard Harding Davis had the misfortune to break two of his fingers. He said Townsend was a strike-breaker and had given information to the police, but it turns out that he is a zealous striker, and was haranguing the mob at the time of the assault. His audience of rioting authors, all of whom belonged to the War Story branch of the Guild, mistook Mr. Davis for an officer of the peace and ran away. Mr. Townsend, who cannot recover and apparently does not wish to, is said to be the author of a popular book called _The Chimney Fadder_. Advices from Boston relate the death of a Pinkerton spy named T. B. Aldrich, who attempted to run the gauntlet of union pickets and enter the premises of The Arena Publishing Company, escorting Walter Blackburn Harte. Mr. Harte was rescued by the police and sailed at once for England. ——————
