This is a lovely wee number - originally published in 1909 it's a kind of satirical ethnography of the British, in all their ridiculousness and customs, written by a well-travelled Sierra Leonean. It's got that quality of the writer being kind of indifferent to the madness of greedy landlords, the pervasiveness of hucksters, the insularity of the middle classes. It's by and large light-hearted, though necessarily takes aim at colonialism, racism, and the absurd stereotypes applied to black folk. Apparently he was asked more than once if he had a tail (!)
It's also interesting to read about two forms of Christianity - the writer's, which is of a more central and imperative role in his life, and that of Londoners in the early 1900s - largely ceremonial, social. Interesting also that this is long before Windrush - so there were fewer black communities in the UK - and this writer is clearly posh as the sun, that the racism he experiences is not so different to what he might experience now.
Anyway yeah - it's a cute and witty wee one, probably ideally suited to a train journey.
