From the book:Certain human beings are admitted to have a genius for discrimination in such matters as objects of art, pigs or stocks. Mrs. Ussher had this same instinct in regard to fashion, especially where fashions in people were concerned. She turned toward hidden social avail-ability very much as the douser's hazel wand turns toward the hidden spring. When she crossed the room to speak to some woman after dinner, whatever that woman's social position might formerly have been, you could be sure that at present she was on the upward wing. When Mrs. Ussher discovered extraordinary qualities of mind and sympathy in some hitherto impossible man, you might be certain it was time to begin to book him in advance.
