burner:

I have a couple of his early books at home. One of them, I think, is "The Downfall of Prempeh."

It's an account of the Ashanti campaign of 1895, and IIRC, it's in that book that he expresses his developing thoughts about what a "boy scout" organization might look like, and why he thought it would be useful to society.

I'll look through it tonight and report back.
