At the present moment, then, the protection against fire in London consists, firstly, in the 300 and odd parish engines (two to each parish), which are paid for out of the rates. The majority of these are very inefficient, not having any persons appointed to work them who possess a competent knowledge of the service. Even women used now and then to fill the arduous post of director; and it is not long since a certain Mrs. Smith, a widow, might be seen at conflagrations, hurrying about in her pattens, directing the firemen of her engine, which belonged to the united parishes of St. Michael Royal and St. Martin Vintry, in the city. We question, indeed, if at the present moment any of the parish-engines are much better officered than in the days of widow Smith, with the exception of those of Hackney, Whitechapel, Islington, and perhaps two or three others. Secondly, there are an unknown number of private engines kept in public buildings, and large manufactories, which sometimes do good service when they arrive early at small fires in their neighborhood, although, singularly enough, when called upon to extinguish a conflagration in their own establishments, they generally "lose their heads," as the Brigade men express it, and very many instances have occurred where even the parish-engines have arrived and set to work before the one on the premises could be brought to bear upon the fire. The cause is clear. The requisite coolness and method which every one can exercise so philosophically in other people's misfortunes, utterly fail them when in trouble themselves. The doctor is wiser in his generation, and is never so foolish as to prescribe for himself or to attend his own family.
