Excerpt from Junior General Science When I was a boy in a country school a forward-looking teacher placed in the school a textbook entitled Natural Philosophy. That book was a storehouse of information. It described in simple language many examples of natural phemena. It was an introduction to the science of interesting everyday things. As a result of the study or reading of this book many of us began to understand in a new way the world about us. It contained little mathematics. Such mathematical problems as it did present could be solved by arithmetic and were t so difficult as to detract from the interest of the book. In the intervening years I have always regarded that book as most valuable. I have heard one of our most distinguished physicists say that books of this kind do more to popularize science for the masses of the people than any similar books of severer scientific pretension. Since that time applied science has been greatly extended, so that it touches our common lives at more points than formerly. Mr. Daniel R. Hodgdon, a science teacher of experience, has prepared a book similar to the one I have briefly described, as a contribution to the field of general science as it exists to-day. It is simple, it has little mathematics, it is free from technicalities, it makes pretense of being exhaustive, and it is, moreover, very interesting. The kind of information that this book and similar books contain should be in the possession of all our young people.
