The subtitle is 'Britain in a Nutshell', and such is what it purports to be. It considers England, Wales, Ireland, and Scotland in turn, pointing out the national characteristics of each, and the distinctive traits of various regions. All is done in staccato sentences, which are supposedly comprehensive but, of course, are nothing of the kind. ('Cambridge always wins the boat race. Cambridge has sausages.')
Yes, the joke is rather one-note, and utterly silly, but it rather beguiled me - as a snapshot of a period, as much as anything else.
The other thing which made this a snapshot of its publication year (1936) was how generous the publisher is with space. It's an above-average-height hardback, and a lot of the pages are almost empty. It adds to the humour (because it becomes all the clearer that they are dismissing places and people in a handful of words) but, to those of us familiar with the 'wartime restrictions' notes in the wafer-thin-paper hardbacks which were soon to follow, it feels anachronistic.
So, a silly book, but just the sort of silly I love.
