Thus to detach an injury done to us, and plant it in space, for mathematical measurement of its weight and bulk, is an art; it may also be an instinct of self-preservation; otherwise, as when mountains crumble adjacent villages are crushed, men of feeling may at any moment be killed outright by the iniquitous and the callous. But, as an art, it should be known to those who are for practising an art so beneficent, that circumstances must lend their aid. Sir Willoughby's instinct even had sat dull and crushed before his conversation with Mrs. Mountstuart. She lifted him to one of his ideals of himself. Among gentlemen he was the English gentleman; with ladies his aim was the Gallican courtier of any period from Louis Treize to Louis Quinze. He could doat on those who led him to talk in that character--backed by English solidity, you understand. Roast beef stood eminent behind the souffle and champagne. An English squire excelling his fellows at hazardous leaps in public, he was additionally a polished whisperer, a lively dialoguer, one for witty bouts, with something in him--capacity for a drive and dig or two--beyond mere wit, as they soon learned who called up his reserves, and had a bosom for pinking. So much for his ideal of himself. Now, Clara not only never evoked, never responded to it, she repelled it; there was no flourishing of it near her. He considerately overlooked these facts in his ordinary calculations; he was a man of honour and she was a girl of beauty; but the accidental blooming of his ideal, with Mrs. Mountstuart, on the very heels of Clara's offence, restored him to full command of his art of detachment, and he thrust her out, quite apart from himself, to contemplate her disgraceful revolutions. Deeply read in the Book of Egoism that he was, he knew the wisdom of the sentence: An injured pride that strikes not out will strike home. What was he to strike with? Ten years younger, Laetitia might have been the instrument. To think of her now was preposterous. Beside Clara she had the hue of Winter under the springing bough. He tossed her away, vexed to the very soul by an ostentatious decay that shrank from comparison with the blooming creature he had to scourge in self-defence, by some agency or other. Mrs. Mountstuart was on the step of her carriage when the silken parasols of the young ladies were descried on a slope of the park, where the yellow green of May-clothed beeches flowed over the brown ground of last year's leaves. "Who's the cavalier?" she inquired. A gentleman escorted them. "Vernon? No! he's pegging at Crossjay," quoth Willoughby. Vernon and Crossjay came out for the boy's half-hour's run before his dinner. Crossjay spied Miss Middleton and was off to meet her at a bound. Vernon followed him leisurely. "The rogue has no cousin, has she?" said Mrs. Mountstuart. "It's a family of one son or one daughter for generations," replied Willoughby. "And Letty Dale?"
