Here's a passage where Westfield talks about possibly having to allow Natives into the European club:
"Got to put up with it, I suppose", he said. "B--s of natives are getting into all the Clubs nowadays. Even the Pegu Club, I'm told. Way this country's going, you know. We're about the last Club in Burma to hold out against 'em"
I can't figure out what the "B--s" is supposed to be. Could it be bollocks? I haven't heard that word being used in this way yet, and it seems weird to me to censor bollocks but not the n-word, although I guess those were different times.
