ABSTRACT
Before the days of modern cities smoke could be sent up into the clean air without harm. Sunlight among the foliage of green trees or dappling the pure stream – sunshine on grass or on distant hills – clear gleams after rain – golden settings and risings – these are the lovely things of the earth. Although an economical method of combustion is likely to pay in the long run, a reform doubtless means a fresh investment of capital on apparatus, or on providing new boiler room, or installing a gas or electric plant. The pile of the feudal castle has given way to the greater pile of the modem factory. Every class in every age in whose control lie the means of production and consequent power over others, needs watching for the public weal. To-day knightly service must be rendered under the quieter name of public duty.
