Mr. Jones, in his "Special reading lists," gives many such references to juvenile literature. Books like Ingersoll's "Country cousins," which contains an article on shell money, also an account of Professor Agassiz's laboratory at Newport; Mary Bamford's "Talks by queer folks," giving many of the superstitions prevalent about animals; the set of books by Uncle Lawrence, "Young folks' ideas," "Queries," and "Whys and wherefores," recently republished under the title "Science in story," and others of this sort, if carefully indexed, answer many of the questions brought every day by children, and amply repay for the trouble. For even if juvenile books are classified on the shelves, much time is wasted in going through many indexes. A wide-awake teacher often gives his pupils the events of the day to study, and if they cannot grasp the situation from the daily papers, juvenile periodicals furnish the best material. For this a classified index is indispensable; it makes available accounts of the workings of government, the weather bureau, mint, and other intangible topics. Until the recent publication of Capt. King's "Cadet days," I knew of no other place to find any description of West Point routine outside of Boynton's or Cullum's histories. One glimpse of either would convince any boy he would rather try some other subject. A short article often suffices to give the main facts. My experience, both as teacher and librarian, persuades me that the average child is eminently statistical. "A horse is an animal with four legs--one at each corner," is fairly representative of the kind of information he seeks. When he becomes diffuse, we may feel sure he has had help. Sissy Jupes are of course to be found, who cannot grapple with facts. Working on this principle, I have made liberal use of a book issued by the U. S. Government--"The growth of industrial art." It gives, in pictures, with only a line or two of description, the progress of different industries--such as the locomotive, from the clumsy engine of 1802 to the elaborate machinery of the present day; the evolution of lighting, from the pine-knot and tallow-dip to the electric light; methods of signalling, from the Indian fire-signal to the telegraph; time-keeping, etc. A child will get more ideas from one page of pictures than from a dozen or more pages of description and hard words.
