The great majority of fires are the result of some individual’s carelessness. Rubbish is left lying about near the cellar furnace; matches are placed where children can reach them; kerosene or gasoline is used to light the kitchen fire; chimneys are allowed to go unrepaired and uncleaned; ends of cigarettes are thrown on the floor or into the waste basket—individual carelessness may take many forms. But every fire is the same size when it starts and a trivial accident may cause the destruction of a whole city. Fire departments are necessary and they should be kept up to the highest efficiency, with well-trained men and motorized apparatus; but dollar for dollar the money spent in prevention brings far more return than expenditures for putting out fires after they occur. The work of fighting fires is spectacular and makes an impression on the people; there is nothing spectacular about _fire prevention_, hence it obtains far less attention from the average individual. Newspapers devote great headlines to the bravery of the fireman who carries somebody down the sheer wall of a high building in the midst of roaring flames and blinding smoke, but the man who quietly builds his tenement so that no such rescue will ever be necessary—he gets no headlines at all. For this the newspapers are of course not to blame; they merely follow the trend of popular interest. =The City’s Share in Health and Welfare Work.=—Many functions which formerly devolved wholly upon the city government have now been taken over to some extent by the state authorities. The state makes the general regulations and prescribes how things shall be done, but the city officials still remain largely responsible for putting the regulations into effect. [Sidenote: The broadening field of municipal activity.] This is true of public health protection, public utilities, poor-relief, correction, sanitation, and education, all of which are dealt with in later chapters of this book. No clear separation between state and local activities can be made nowadays, the two overlap and are intermixed. The city still retains, however, almost complete responsibility for the care of its streets, for street lighting, for the maintenance of parks, and for the provision of recreation. But whether it acts merely as the agent of the state or entirely on its own behalf the city’s functions are being broadened year by year. It is expected to do more and more for the social welfare of its people. [Sidenote: A typical example.]
