And yet they _had_ something to do with that engine, or, rather, it had to do with them. But for it, and the rest of the Red Brigade, London would have long ago been in ashes. It is only by unremitting vigilance and incessant action that the London fires can be kept within bounds. There are nearly two thousand fires in the year in the metropolis, and the heroic little army which keeps these in check numbers only three hundred and seventy-eight men. That this force is much too small for the work to be done is proved by the fact, that the same men have sometimes to turn out three, four or five times in a night, to work of the most trying and dangerous nature. There is no occupation in which the lives of the men employed are so frequently risked, and their physical endurance so severely tried, as that of a London fireman. As there are, on the average, five fires every night all the year round, it follows that he is liable to be called out several times every night; and, in point of fact, this actually takes place very often. Sometimes he has barely returned from a fire, and put off his drenched garments, when he receives another "call," and is obliged to put them on again, and go forth weary--it may be fasting--to engage in another skirmish with the flames. In all weathers and at all seasons--hot or cold, wet or dry--he must turn out at a moment's notice, to find himself, almost before he is well awake, in the midst of stifling smoke, obliged to face and to endure the power of roasting flames, to stand under cataracts of water, beside tottering walls and gables, or to plunge through smoke and flames, in order to rescue human lives. Liability to be called _occasionally_ to the exercise of such courage and endurance is severe enough; it is what every soldier is liable to in time of war, and the lifeboat-man in times of storm; but to be liable to such calls several times every day and night all round the year is hard indeed, and proves that the Red Brigade, although almost perfect in its organisation and heroic in its elements, is far too small. Paris has about seven hundred fires a year; New York somewhere about three hundred; yet these cities have a far larger body of firemen than London, which with little short of two thousand fires a year, does her work of extinction with only three hundred and seventy-eight men!
