Sinopsis

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.

Excerpt from American Inventions and Inventors

A school history should set forth such facts, and in such an order, as to show the progress of civilization. The great lessons of history are found in that line of events in the past which exhibits the progress of mankind - the uplift of humanity. The record of no other country can present a more startling array of forward movements and upward tendencies than that of our own land, and in no one direction does this upward movement appear quite so clearly as in the line of inventions.

Mans efforts are, first, to overcome nature. Food, shelter, and clothing are his primary wants. After these are supplied, he rises to higher realms of thought and action. Then he nourishes his intellect, exercises his sensibilities, and provides nutriment for his soul, that it, also, may grow. In this book the above logical order is followed.

It is painfully evident that many school-children dislike the study of history. The authors of this book believe that this need not be. It is clear that the study should be undertaken at an earlier age than is usually the case in our public schools. It is not necessary, and oftentimes not desirable, that the books of history should be studied as text-books. Frequently they should be used as reading books. Such use is more likely to develop in the minds of the younger children a love for history.

This book, while adapted to older persons, has been prepared with special reference to the needs and capacities of children from ten to twelve years of age. It is commended to teachers and parents with full confidence that they will find it useful, and that the children will be both interested and profited by its perusal.
