Ok here are some links I have found. And I want to give a shout out to @Kudu and his Inquiry.net website. It has a wealth of information there. And I want to apologize about the wrong year for the 3rd edition of the SMHB, it was published in 1936, not 1929.
Ok here to the links that can help.
http://scoutmastertroop56.weebly.com/uploads/1/6/8/6/16867144/the_patrol_method_helps_for_scoutmasters.pdf links to a 1938 pamphlet to help SMs. While Bill is not credited, he probably wrote it.
http://inquiry.net/patrol/index.htm Is a ton of resources on the Patrol Method.
I believe this is Hillcourt's training regimen. @Kudu, please correct me if I am wrong.
Start of the training http://inquiry.net/patrol/green_bar/index.htm
1st meeting http://inquiry.net/patrol/green_bar/1st.htm
2nd meeting http://www.inquiry.net/patrol/green_bar/2nd.htm
3rd meeting http://www.inquiry.net/patrol/green_bar/3rd.htm
4th meeting http://www.inquiry.net/patrol/green_bar/4th.htm
5th meeting http://www.inquiry.net/patrol/green_bar/5th.htm
6th meeting http://www.inquiry.net/patrol/green_bar/6th.htm
PLC Camp Out http://www.inquiry.net/patrol/green_bar/6z_camp.htm
As I stated previously, not advancement oriented, but establishing a youth run troop oriented.
Kudu also has posted other materials on training Scouts as well.
Another source of info is http://www.thedump.scoutscan.com/nonfict.html Looks to be Canadian in origin. EH!
Hope this helps.
Seriously though, I will be looking to see if anyone has posted Bill's stuff to the net. Again I lent my copy of the 3rd edition SM handbook, to a Scoutreach SM to help him out. He used it to start 4 troops that he was the SM for. Sadly when he left the area, no one in the troops stepped up to the plate, and they folded.
And I didn't get the book back either.
@Eagle94-A1 Post a link to Green Bar Bill's ideas on how to start a new troop.
One challenge always is for the kids to figure out who would be a good leader and getting to know each other so they can vote on who would be a good PL (or SPL).
I'd suggest the first meeting include one or two get to know you games. And, run the games so that the girls start asserting their personality. You will quickly know who would do well standing up in front of others and helping keep things moving.
I'd also start PL (SPL) early, but keep it simple. Then continually grow their role as they are ready. Continually though, focus on them having positive experiences as a leader. Otherwise, it can be intimidating and will scare off future scouts from volunteering to do.
