a "camp fraternity" was the way to improve the summer camp experience and to encourage older Scouts to continue attending Scout summer camp. In developing this program they borrowed from the traditions and practices of several other organizations. Edward Cave's Boy's Camp Book (1914) was consulted for the concept of a camp society that would perpetuate camp traditions. College fraternities were also influential for their concepts of brotherhood and rituals, and the idea of new members pledging themselves to the new organization. Inspired by Ernest Thompson Seton's previous Woodcraft Indians program, American Indian motifs were used to make the organization interesting and appealing to youth. Other influences include the Brotherhood of Andrew and Phillip, a Presbyterian church youth group with which Goodman had been involved as a young man, and Freemasonry. The traditions and rituals of Freemasonry contributed more to the basic structure of the OA ritual than any other organization. In fact, there appears to be no known fraternal organization more faithful in form to Freemasonry than the OA. Familiar terms such as "lodge" and "obligation" were borrowed from Masonic practice, as were most of the ceremonial structures and ritual formulae. Even the early national meeting was called a "Grand Lodge," a Masonic reference. Goodman and Edson ultimately devised a program where troops chose, at the summer camp's conclusion, those boys from among their number who they felt best exemplified the ideals of Scouting. Those elected were acknowledged as having displayed, in the eyes of their fellow Scouts, a spirit of unselfish service and brotherhood. Edson and Goodman said they "based the OA's lore and ceremonies on the lore of the Lenni Lenape Indians who had occupied Treasure Island in earlier times" and based the group's structure "on a loose interpretation of Hiawatha and Last of the Mohicans", both popular works of fiction by Henry Wadsworth Longfellow and James Fenimore Cooper, respectively. The Scouts considered this move a success, and went on to repeat this pattern the following summer at Treasure Island. Those Scouts honored at Treasure Island in 1915 and 1916 would become members of what is now Unami Lodge. By 1921, Goodman had spoken to Scout leaders in surrounding states about their honor society, which resulted in multiple lodges being established by Scout councils in the northeastern United States. The name of the society was then changed to Order of the Arrow, and in October 1921, Goodman
