In 1916, Calcutta's Senior Deputy Commissioner of Police J. S. Wilson introduced "Scouting for Boys" as a textbook in the Calcutta Police Training School. Colonel Wilson volunteered his services to the District Scout Commissioner, Alfred Pickford, and in 1917 became Assistant Scoutmaster of the Old Mission Church Troop. Together the two struggled for the admission of Indian boys into The Scout Association, which had not been admitted due to a Government of India order against it because "Scouting might train them to become revolutionaries". Shortly Wilson was acting as Cubmaster and Scoutmaster, and succeeded Pickford as District Commissioner in May 1919 when Pickford was promoted to Chief Scout Commissioner for India.
