Delivered by the firmness of our government, and the spirit of our people--by the wisdom which centuries of freedom has diffused, and the habits which wide-spread and long-continued prosperity have rendered general--from the immediate dangers of a similar convulsion, it well becomes us to take advantage of the breathing time thus afforded, to consider how we may lessen the danger in future times, and remove those causes which rendered it serious in the crisis through which we have passed. It is in vain to conceal that the danger was very great. For the first time for a hundred and sixty years, Revolution walked our streets; a large portion of our manufacturing population looked only for the telegraph from London on the 10th April to commence the work of insurrection. That such insane attempts would have been defeated is indeed certain; but what unutterable misery to the persons engaged in them, and the whole industrious population in the realm, awaited the successful issue of treason, even for a brief period, and in a single city? If Glasgow had been three days in the hands of the mob after the 6th March; if a portion even of London had remained in the possession of the Chartists on the night of the 10th April; if Dublin had become the theatre of a second rebellion on the 17th March, and Sackville Street had witnessed the throwing of rockets and storming of barricades, as Elbœuf and Rouen have lately done, who can estimate the shock which would have been given to industry, the ruin to capital, the destruction of employment, that must inevitably have ensued throughout the empire? It would not have been--as was said of the failure of the potatoes in Ireland--a famine of the thirteenth, with the population of the nineteenth century; it would have been the horrors of the Jacquerie, decimating the myriads of ancient Babylon.
