From the first days of the Scouting Movement, boys under the minimum age of 14 wanted to get involved. In Britain, the birthplace of Scouting, a "Wolf Cub" program began relatively early with the publication of "The Wolf Cub Handbook" in 1916 by Robert Baden-Powell himself. In the United States it took longer for the idea to be adopted, mainly due to the reluctance of Chief Scout Executive James E. West. The "Younger Boy Problem" was studied off and on for many years until it became an official experiment in 1929 and was adopted in 1930 as "Cubs BSA". Cub Scouting has continued to evolve as ever-younger boys are shown to benefit from structured activity and "fun with a purpose" led by dedicated adults. First grade boys are now welcomed into Tiger Cub dens, and experimental "Lion Cub" dens with Kindergarten aged boys are being studied by the Northern Star Council, with an eye to national adoption of the program in 2014.
