What is the meaning of Boy scout?

Orig., a member of the "Boy Scouts," an organization of boys founded in 1908, by Sir R. S. S. Baden-Powell, to promote good citizenship by creating in them a spirit of civic duty and of usefulness to others, by stimulating their interest in wholesome mental, moral, industrial, and physical activities, etc. Hence, a member of any of the other similar organizations, which are now worldwide. In "The Boy Scouts of America" the local councils are generally under a scout commissioner, under whose supervision are scout masters, each in charge of a troop of two or more patrols of eight scouts each, who are of three classes, tenderfoot, second-class scout, and first-class scout.
