Conway had no race or color prejudice, and it was an affectation for him to pretend, as he sometimes did in clubs and first-class railway carriages, that he set any particular store on the "whiteness" of a lobster-red face under a topee. It saved trouble to let it be so assumed, especially in India, and Conway was a conscientious trouble-saver. But in China it had been less necessary; he had had many Chinese friends, and it had never occurred to him to treat them as inferiors. Hence, in his intercourse with Chang, he was sufficiently unpreoccupied to see in him a mannered old gentleman who might not be entirely trustworthy, but who was certainly of high intelligence. Mallinson, on the other hand, tended to regard him through the bars of an imaginary cage; Miss Brinklow was sharp and sprightly, as with the heathen in his blindness; while Barnard's wise-cracking bonhomie was of the kind he would have cultivated with a butler.
Interesting. Not what I had expected given some of the earlier comments in the book.
