George Lower was inducted into the Order of the Arrow (OA) at Treasure Island during the second summer of Wimachtendienk in 1916. He was one of the two major contributors to the writing of the rituals used by the Grand Lodge from 1921 until 1936. Prior to 1921, Lower was one of the quiet adult forces within the Wimachtendienk. In a newspaper article in August 1921, he is pictured in a sash and black robe and identified as one of two Medicine Men along with Dr. William M. Hinkle.
In 1921, for his leadership and influence in the Wimachtendienk W. W., George Lower became the sixth Arrowman to receive the Third Degree.
On November 8, 1934 National Chief Thomas Cairns wrote to George Lower asking for his assistance regarding transformation of the ceremonies critical to the integration of the OA into the BSA:
This step has brought to light a number of rather interesting questions and I should like, if at all possible, to secure your help in answering one of these.
In the Ritual (copy enclosed) on pages 9, 11, 13, and 22 the Meteu is called upon to say a prayer. This Ritual has been submitted to the National Scout Committee on Church Relations and by them to their subdivisions on Protestant, Catholic and Jewish Scouting. There is a common agreement, conveyed to me by Urner Goodman, of the desirability of eliminating from the Ritual these prayers as such since it is extremely difficult to have any one prayer which is acceptable to all three groups.
George Lower wrote back to Thomas Cairns on January 6, 1935. George Lower had become inactive in the OA and was a teacher at the Westtown School, Westtown, Pennsylvania. Along with agreeing to do the re-writes, George Lower wrote:
Receiving your request recalled to my mind the hours and hours Dr. Hinkle and I spent on this ritual years ago and I was quite surprised to see that it had not been changed since our last revision.
Lower completed the revisions of the ceremonies and the OA published them in 1936.
