In 1925, Dr. Huber W. Hurt, a research psychologist and veteran Scouter, was authorized to study existing organizations for younger boys, such as Boy Rangers, Boy Pioneers, American Eagles, and Boys' Clubs. He found that only one boy in 50 participated regularly in any type of organized leisure-time program. He also found that younger boys responded better to leadership and program efforts than older boys. He worked closely with Ernest Thompson Seton. Both men recommended that the BSA adopt a program for younger boys, with older Boy Scouts as leaders, to tie into home, church, school, and Boy Scouting.
The National Executive Board authorized the Chief Scout Executive to thoroughly investigate the matter. An advisory committee worked with the BSA to develop a plan and produce the necessary literature. Advice was obtained from leading psychologists, sociologists, teachers, school superintendents, professors of education, college executives, and recreation and welfare directors.
By 1929, the new Cubbing program (it wasn't called "Cub Scouting" until several years later) was taking shape and was introduced as a demonstration project in a limited number of communities. Its structure was similar to today's Cub Scouting, except that dens were led by Boy Scout den chiefs. The plan included a neighborhood mothers' committee to encourage Cubs and den chiefs.
In 1930, Cub Scouting was formally launched, with 5,102 boys registered at the end of that first year. By 1933 the time had come to promote Cub Scouting throughout the country as a part of Scouting. All experimental restrictions were removed, and the first national director of Cub Scouting was appointed.
Hmmm. Sound familiar? By the way, if you don't have a Den Chief, see about getting one. Your troop's Scoutmaster should be able to make a great recommendation.
