Excerpt from American Inventions and Inventors While we watch the steamer glide around Castle Garden into East River, evening begins to come on; we must hasten uptown. As we pass along Broadway, lights flash out in the darkness and our thoughts are again turned to fire and steam. We have heard that the source of the electric light is in the dynamo, and that steam power is used to turn that great machine. The enormous engine, the mammoth boat, the brilliant light - all need the power of steam, and nothing but fire will produce this steam. What, then, is fire? And is its only use that of changing quiet, liquid water into powerful steam? Let us see. Did you notice that machine shop which we passed when we were in Cleveland a few days ago? Did you see those furnaces with the huge volumes of flame bursting out of the open doors? You know that great heat is necessary to make tools and other implements of iron, and all the instruments of everyday life that are formed out of metals. Our pens and needles, our hoes and rakes, our horseshoes, our stoves and furnaces, our registers and the iron of our desks - all de pend upon heat for their production. Fire can do much for us. To change water into steam is but one of its powers. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
