     summary: The practical idea of invoking great men. No longer can great men and great events be aimed at it and glanced off on it--into single nations.

     summary: Such water engines have come into vogue only in comparatively recent times, being suggested by the steam engine. In the present volume we are concerned with those primitive applications of force through which man early learned to add to his working efficiency, and with the elaborate mechanisms--turbine wheels, steam engines, dynamos--through which he has been enabled to multiply his powers until it is scarcely exaggeration to say that he has made all Nature subservient to his will.

     summary: Its success has led to the purchase of other motor engines, some fitted with a chemical apparatus, which, by the action of acid on a solution of soda in closed cylinders, is enabled to fling water impregnated with carbonic acid gas on to the fire the moment it arrives within working distance of the conflagration, and gives very valuable first aid while the pumping apparatus is being got into order. The latest thing in motor fire engines is one which carries a fire-escape with it, in addition to water-flinging machinery.
