Never, throughout the annals of universal Christendom, has there indeed been any act of one solitary insulated individual, armed with power so appalling over the hearts of men, as that exterminating murder, by which, during the winter of 1812, John Williams in one hour, smote two houses with emptiness, exterminated all but two entire households, and asserted his own supremacy above all the children of Cain. It would be absolutely impossible adequately to describe the frenzy of feelings which, throughout the next fortnight, mastered the popular heart; the mere delirium of indignant horror in some, the mere delirium of panic in others. For twelve succeeding days, under some groundless notion that the unknown murderer had quitted London, the panic which had convulsed the mighty metropolis diffused itself all over the island. I was myself at that time nearly three hundred miles from London; but there, and everywhere, the panic was indescribable. One lady, my next neighbor, whom personally I knew, living at the moment, during the absence of her husband, with a few servants in a very solitary house, never rested until she had placed eighteen doors (so she told me, and, indeed, satisfied me by ocular proof), each secured by ponderous bolts, and bars, and chains, between her own bedroom and any intruder of human build. To reach her, even in her drawing-room, was like going, as a flag of truce, into a beleaguered fortress; at every sixth step one was stopped by a sort of portcullis. The panic was not confined to the rich; women in the humblest ranks more than once died upon the spot, from the shock attending some suspicious attempts at intrusion upon the part of vagrants, meditating probably nothing worse than a robbery, but whom the poor women, misled by the London newspapers, had fancied to be the dreadful London murderer. Meantime, this solitary artist, that rested in the centre of London, self-supported by his own conscious grandeur, as a domestic Attila, or 'scourge of God;' this man, that walked in darkness, and relied upon murder (as afterwards transpired) for bread, for clothes, for promotion in life, was silently preparing an effectual answer to the public journals; and on the twelfth day after his inaugural murder, he advertised his presence in London, and published to all men the absurdity of ascribing to _him_ any ruralizing propensities, by striking a second blow, and accomplishing a second family extermination. Somewhat lightened was the _provincial_ panic by this proof that the murderer had not condescended to sneak into the country, or to abandon for a moment, under any motive of caution or fear, the great metropolitan _castra stativa_ of gigantic crime, seated for ever on the Thames. In fact, the great artist disdained a provincial reputation; and he must have felt, as a case of ludicrous disproportion, the contrast between a country town or village, on the one hand, and, on the other, a work more lasting than
