This classic work about all aspects of farming has been immensely enhanced by the inclusion of striking pictures and images to explain and amplify the text. The most successful farmers are those who work in harmony with the forces of nature that control the growth and development of plants and animals. These hardscrabble men have gained their knowledge by careful observation, experiment, and doing. This book covers the principles of farming. A number of simple experiments have been added to make the work more interesting to the general reader, and aid the prospective farmer in making simple investigations for himself. However, the best observations begin on the farm. The plant is the central and all-important factor. And the root is the most important part of the plant to the plant grower. The conditions necessary for the growth and development of plant roots are regarded as the fundamental principles of all agriculture."
