The Scientific American as it comes to us each week is filled with most useful and practical matter. It keeps close watch of every field of science and industry, and is a faithful recorder of the progress that is being made. It employs none but the most thoroughly competent writers, and consequently its information is always reliable. It is a paper for men, and at the same time it is pre-eminently the paper for boys. Its matter has the advantage of being solid and substantial, while it is also most interesting as well. Boys will pore over its pages by the hour. And when they turn away from its study, their minds are filled with useful facts about farming, fruit-raising, carpentering, machinery, etc., etc. For there is no field of the useful vocations of life from which this valuable paper does not bring you interesting sheaves of desirable knowledge. If parents will furnish themselves and their children with such papers as the Scientific American, instead of those that are more or less filled with stories of highway robberies, conflicts with policemen, hair-breadth escapes from bears and the like, they will see their sons grow into useful men rather than “border ruffians.” Munn & Co., 361 Broadway, New York City, are the publishers of the Scientific American, and they are always glad to send sample copies, and answer the inquiries of those who may become interested in the paper.
