“It’s the only Xingu in the Encyclopaedia; and she _has_ been living in Brazil,” Miss Van Vluyck persisted. “Yes: her brother has a consulship there,” Mrs. Leveret interposed. “But it’s too ridiculous! I--we--why we _all_ remember studying Xingu last year--or the year before last,” Mrs. Ballinger stammered. “I thought I did when _you_ said so,” Laura Glyde avowed. “I said so?” cried Mrs. Ballinger. “Yes. You said it had crowded everything else out of your mind.” “Well _you_ said it had changed your whole life!” “For that matter. Miss Van Vluyck said she had never grudged the time she’d given it.” Mrs. Plinth interposed: “I made it clear that I knew nothing whatever of the original.” Mrs. Ballinger broke off the dispute with a groan. “Oh, what does it all matter if she’s been making fools of us? I believe Miss Van Vluyck’s right--she was talking of the river all the while!” “How could she? It’s too preposterous,” Miss Glyde exclaimed. “Listen.” Miss Van Vluyck had repossessed herself of the Encyclopaedia, and restored her spectacles to a nose reddened by excitement. “‘The Xingu, one of the principal rivers of Brazil, rises on the plateau of Mato Grosso, and flows in a northerly direction for a length of no less than one thousand one hundred and eighteen miles, entering the Amazon near the mouth of the latter river. The upper course of the Xingu is auriferous and fed by numerous branches. Its source was first discovered in 1884 by the German explorer von den Steinen, after a difficult and dangerous expedition through a region inhabited by tribes still in the Stone Age of culture.’” The ladies received this communication in a state of stupefied silence from which Mrs. Leveret was the first to rally. “She certainly _did_ speak of its having branches.” The word seemed to snap the last thread of their incredulity. “And of its great length,” gasped Mrs. Ballinger. “She said it was awfully deep, and you couldn’t skip--you just had to wade through,” Miss Glyde added. The idea worked its way more slowly through Mrs. Plinth’s compact resistances. “How could there be anything improper about a river?” she enquired. “Improper?” “Why, what she said about the source--that it was corrupt?” “Not corrupt, but hard to get at,” Laura Glyde corrected. “Some one who’d been there had told her so. I daresay it was the explorer himself--doesn’t it say the expedition was dangerous?” “‘Difficult and dangerous,’” read Miss Van Vluyck. Mrs. Ballinger pressed her hands to her throbbing temples. “There’s nothing she said that wouldn’t apply to a river--to this river!” She swung about excitedly to the other members. “Why, do you remember her telling us that she hadn’t read ‘The Supreme Instant’ because she’d taken it on a boating party while she was staying with her brother, and some one had ‘shied’ it overboard--‘shied’ of course was her own expression.” The ladies breathlessly signified that the expression had not escaped them.
