In September 1925 organizers formed a council headquartered in Rockland—Pine Tree Council. Camden was added to this council in 1928, but then Pine Tree Council was absorbed into Cumberland County Council in 1929. The latter council had been growing quite nicely already, as it had added eight towns in Oxford County in May 1929. Also added in 1929 were units in Sagadahoc, Franklin, and Kennebec Counties, as well as those in parts of Knox, Lincoln, and Somerset Counties. Five more towns in Knox County were added in 1930.
