convened the first national meeting of what at that time was called the "National Lodge of the Order of the Arrow" in Philadelphia—where Goodman was elected as Grand Chieftain. Committees were organized to formulate a constitution, refine ceremonial rituals, devise insignia, and plan future development. In the early 1920s, many Scout executives were skeptical of what they called "secret camp fraternities." By September 1922, opposition to the Order of the Arrow was such that a formal resolution opposing "camp fraternities" was proposed at a national meeting of Scout executives. Goodman argued against the motion: "Using the Scout ideals as our great objective", he said, a camp activity that will "further the advancement of those ideals" should not be suppressed. The motion was narrowly defeated, and the fledgling Order continued as an experimental program throughout the 1920s and 1930s. In 1931, there were OA lodges in 7 percent of BSA councils nationwide. By 1948, about two-thirds of the BSA's councils had established OA lodges. That year, the OA was also integrated as an official part of the Scouting program. 21st century Over the century since the Order of the Arrow's founding, more than one million Scouts and Scouters have worn the OA sash on their uniforms, denoting membership in the Brotherhood. The four stated purposes of the Order of the Arrow are: "(1) Recognize those who best exemplify the Scout Oath and Law in their daily lives and through that recognition cause others to conduct themselves in a way that warrants similar recognition; (2) Promote camping, responsible outdoor adventure, and environmental stewardship as essential components of every Scout’s experience, in the unit, year-round, and in summer camp; (3) Develop leaders with the willingness, character, spirit and ability to advance the activities of their units, our Brotherhood, Scouting, and ultimately our nation; and (4) Crystallize the Scout habit of helpfulness into a life purpose of leadership in cheerful service to others. In a new program of national service conducted from June through August 2008, the OA offered ArrowCorps5 to both youth and adult Arrowmen. Described as "one of the largest conservation efforts in Scouting's history" by the Boy Scouts of America, approximately 3,500 Arrowmen converged on five national forests to work on various conservation projects such as building new trails and helping preserve nearly extinct species, as well as removing invasive species, in cooperation with the U.S. Forest Service.
