And now the talk took a capricious turn, as it will do occasionally, in those companies where people are old-fashioned enough to “sit” after dinner, and let the decanter circulate. Even here, however, conversation could not run smoothly. Ogden launched into the manufacture of wines, the chemistry of adulterations, and the grape disease, on every one of which Layton found something to correct him,--some slip or error to set right,--an annoyance all the more poignant that Karstairs seemed to enjoy it heartily. From fabricated wines to poisons the transition was easy, and they began to talk of certain curious trials wherein the medical testimony formed the turning-point of conviction. Here, again, Layton was his superior in information, and made the superiority felt. Of what the most subtle tests consisted, and wherein their fallacy lay, he was thoroughly master, while his retentive memory supplied a vast variety of curious and interesting illustration. Has our reader ever “assisted” at a scene where the great talker of a company has unexpectedly found himself confronted by some unknown, undistinguished competitor, who, with the pertinacity of an actual persecution, will follow him through all the devious windings of an evening's conversation, ever present to correct, contradict, amend, or refute? In vain the hunted martyr seeks out some new line of country, or starts new game; his tormentor is ever close behind him. Ogden wandered from law to literature. He tried art, scientific discovery, religious controversy, agriculture, foreign travel, the drama, and field sports; and Layton followed him through all,--always able to take up the theme and carry it beyond where the other had halted. If Millar underwent all the tortures of an unhappy host at this, Karstairs was in ecstasy. He had been spending a week at the Rectory in Ogden's company, and it seemed a sort of just retribution now that this dictatorial personage should have met his persecutor. Layton, always drinking deeply as the wine came to him, and excited by a sort of conflict which for years back he had never known, grew more and more daring in his contradictions, less deferential, and less fearful of offending. Whatever little reserve he had felt at first, oozed away as the evening advanced. The law of physics is the rule of morals, and as the swing of the pendulum is greater in proportion to the retraction, so the bashful man, once emancipated from his reserve, becomes the most daringly aggressive to mortals. Not content with refuting, he now ridiculed; his vein of banter was his richest, and he indulged it in all the easy freedom of one who defied reprisals. Millar tried once or twice to interpose, and was at last fain to suggest that, as the decanters came round untouched, they should adjourn to coffee. Ogden rose abruptly at the intimation, and, muttering something inaudible, led the way into the drawing-room.
