A book from past. Brought me from far.
I like to read the original sources, opinions, point of views.
The booklet was written in an age when the founder of the Toastmasters International, still was not convinced that we should call a critic 'evaluator'... but it does have detailed explanation why critic is needed, how to go about it, how long, what look for, and so on.
I am not sure, but I think it must be written about the age I was born, that is 77 years ago!
