This weekend, I decided to take a look at a couple of books in my personal library, to see if they were a source for info on Wilder.
The Golden Book of Scouting, written for the 50th anniversary, is the source for the story on Kimo Wilder becoming Chief Seascout, and paying for the cost of the salary of the Sea Scout Department out of his own pocket.
William Murray's History of the BSA book is the source of saying the Department of Sea Scouting was composed of 3 people: Wilder, "Skipper Horton", and a third man who served as their secretary. "Skipper Horton" is obviously Herbert G. Horton, who apparently held the title of "Chief Pilot", not Skipper, and was a naval reservist.
Also, while Wilder's Sea Scout Manual is the first true BSA Sea Scout manual, its actually considered the 4th. Warrington B-P's, Carey's, and Longstreth's are considered the 1st, 2nd, and 3rd.
