Ernest Thompson Seton started the Woodcraft Indians in 1902 and published "The Birch Bark Roll of the Woodcraft Indians" in 1906. Daniel Carter Beard started the Sons of Daniel Boone in 1905. When Baden-Powell created the first Scouting program in 1907, he used elements of Setons' work in his "Scouting for Boys". Several small local Scouting programs started in the U.S. soon after, most notably the Boy Scouts of the United States (BSUS), the National Scouts of America (NSA) and the Peace Scouts of California—these later merged into the BSA soon after it was formed. The Southern Baptist Convention’s Royal Ambassadors was founded in 1908 for elementary-school-aged boys. The YMCA in Michigan was organizing Scout troops based on "Scouting for Boys" as early as 1909. Salvation Army founder William Booth met with Baden-Powell for discussion about a possible Salvationist Scouting program. The Salvation Army thus began its Life Saving Scouts of the World in 1913. The BSUS was started by the National Highway Protective Association and led by Peter S. Bomus. William Verbeck, Adjutant General of New York State, was leader of the National Scouts. Both the BSUS and NSA were both more military in style.
