I recently picked up a copy of The Oxford Pocket Book of Cricket Coaching, by D.C.H. Townsend (Oxford University & England), first published in 1953, with a second impression in 1955.
Not surprisingly, the book, written after the first M.C.C. Coaching Conference, in December 1951, describes a fairly formal and traditional description of the key techniques of the game.
Interesting as an historical document, but with a few ideas that would not look so out-of-place in the curriculum of the most maverick coaching programmes today.
