Alphabetically, categorically (automobiles; balls and dances; business matters; etc. with subdivisions) and cross-indexed (alibis--see apologies and excuses) this is twice as voluminous, page-wise, as the Post and Vanderbilt it frequently supplements. With an alibi--we have not seen the index--it is hard to say how easy this will be to use and certainly some of the material has been optionally included: i.e. handling your child's allowance, or stopping payment on a check. However the book is more modern and democratic in tone--and while putting down people who chew gum or wear curlers publicly, it at least acknowledges the possibility. And along with all the high protocol of formal occasions, it does deal with many daily practicalities with not too many lapses. (Say speaking of soup--while telling you how to fill the spoon, it never mentions at what angle you empty it?) All in all very substantial coverage, casual but definite and an introduction by Cleveland Amory.
