No claims are made for originality or discovery, but if there is merit in the work, it lies in the practical applica tion of scientific facts to the everyday problems and conditions as they are found on the farm. In the treatment of the various subjects I have tried to present them in the briefest way, and have given the results of scientific research as far as known and as far as they square with practical experience, leaving all theories in the hands of experimenter and investigator. This should enable the reader to secure a fairly accurate knowledge of the subject in which he is interested with out the necessity of searching through many bulletins and elementary works. The subjects treated are believed to be those in which the great majority of farmers are most interested. The science of agriculture (if, strictly speaking, there is such a science) is as broad as the universe, embracing within its domain, to some extent, all other sciences, presenting rich fields in many directions for investigation and discovery, and awaiting the intelligent application of such discoveries to agricultural conditions as we find them.
