Excerpt from Practical Farm Drainage a Manual for Farmer and Student
Twenty-five years ago "Practical Farm Drainage" was prepared by the author to meet an urgent demand for a simple manual upon the draining of farm lands. At that time the value of under-drainage was only beginning to be appreciated, but soon became recognized as an improvement of great importance in the development of agriculture. The book was cordially received, and the demand for it has been continuous. Now, after an added experience of twenty-five years, during which the author has been closely identified with many and varied drainage projects throughout the United States, he has entirely rewritten the book, bringing it up to date and adding much valuable matter. This new edition he herewith presents for the use of farmers and students. For a more complete discussion of drainage engineering and the larger problems connected with the subject, the reader is referred to the authors work on "Engineering for Land Drainage."
