—Riots have been of almost daily occurrence the week in Montreal, some of which have assumed a very formidable character. Monday night a furious mob attacked several public buildings, including the central police station, East End branch of the health office, and the County House, smashing windows and causing general destruction. The military was ordered out, and after a hard fight police succeeded in restoring quiet. The chief cause ls Canadian aversion to compulsory vaccination, which is being enforced by the Board of Health.
