Joseph Bushnell Ames
I can find little about Joseph Bushnell Ames, except for his being listed as author on a number of books - one of which has "Boy Scouts" in the title.
Most of his output seems to have been westerns. IMDB lists him as writer for a Tom Mix film entitled Catch My Smoke.
His book Under Boy Scout Colors has "APPROVED BY THE BOY SCOUTS OF AMERICA” on its title page, so he's included as a BSA-approved author.
The title page also includes "TO THE MEMBERS OF TROOP FIVE - FROM A GRATEFUL SCOUTMASTER" - which would suggest that he was active in scouting.
