'I don't think, talking of Americans, that I've told you about an old couple called Williams Jackson who have "debouchés" here as the trimmings of an American commission sent out on Persian relief work. He's a learned Professor who wrote the "Life of Zoroaster" and other works (all of which I have by good fortune read) and she's a nice old thing [...] I've made bosom friends with both of them, especially with the Professor. They brim over with universal kindness and American sentimentality — a quality quite as truly American as hard-headedness.'
