She had the valuable gift of sitting still without stiffness, and not fidgetting with fan, bouquet, or hand-kerchief, as she listened or talked. Rosa's mercurial temperament betrayed itself, every instant, in the bird-like turn of her small head, the fluttering or chafing of her brown fingers, and not unfrequently by an impatient stamp, or other movement of her foot that exposed fairy toe and instep. Contemplation of the one rested and refreshed the observer; of the other, amused and excited him. Mr. Dorrance's phlegmatic nature found supreme content in dwelling upon the incarnation of patrician tranquillity at his right hand, and he regarded the actions of his frisky would-be tormentor very much as a placid, well-gorged salmon would survey, from his bed of ease upon the bottom of a stream, the gyrations of a painted dragon fly overhead. A lull in the general conversation--the reaction after a hearty laugh at a happy repartee--gave others besides Mabel the opportunity of profiting by his learned remarks. “But does not that seem to you a short-sighted policy,” he was urging upon his auditor, with the assistance of a thumb and forefinger of one hand, joined as upon a pinch of snuff, and tapping the centre of the other palm; “does not that appear inexcusable profligacy of extravagance, which fells and consumes whole surface forests of magnificent trees--virgin growth--(I use the term as it is usually applied, although, philosophically considered, it is inaccurate) giants, which centuries will not replace, instead of seeking beneath the superficial covering of mould, nourishing these, for the exhaustless riches, carboniferous remains of antediluvian woods, hidden in the bowels of your mountains, and underlying your worn-out fields?” Rosa was shaking with internal laughter--she would give no escape except through her dancing eyes. Indeed, Mr. Dorrance's was the only staid countenance there, as Mabel said, pleasantly, moving her chair beyond the bounds of the ring, “I, for one, find the combustion of the upper forest growth too powerful, just at this instant. This is a genuine Christmas-storm--is it not? Listen to the wind?” In the stillness enjoined by her gesture, the growl of the blast in the chimney and in the grove; the groaning, tapping, and creaking of the tree branches; the pelting sleet and the rattle of casements all over the house brought to the least imaginative a picture of out-door desolation and fireside comfort that prolonged the hush of attention. Tom Barksdale's pretty wife slipped her hand covertly into his tight grasp, and their smile was of mutual congratulation that they were brightly and warmly housed and together. Rosa, preternaturally grave and quiet, lapsed into a profound study of the mountain of red-hot embers. Several young ladies shuddered audibly, as well as visibly, and were reassured by a whispered word, or the slightest conceivable movement of their gallants' chairs nearer their own.
