"MERRY MAGICIAN" GONE MAD
Louis Krieger, of this city, known in the Adirondack Mountain towns, which he was wont to tour during the Summer seasons as "The Merry Magician," was brought back by his son, James Krieger, who had received a telegram stating that his father was acting queerly.
On the train the elder Krieger became violent and attacked the younger man, nearly choking him into unconsciousness. Arrived at the Harlem Station of the New York Central, with the assistance of Patrolman McDermott, Krieger was conveyed to the psychopathic ward at Bellevue for observation.
