THE PRINCIPLES AND PRACTICE OF LAND DRAINAGE: EMBRACING A BRIEF HISTORY OF UNDERDRAINING; A DETAILED EXAMINA TICAL DIRECTIONS FOR THEIR CONSTRUCTION: THE MANUFACTURE OF DRAIN-TILE, ETC. Author of the "Wheat Plant," Corresponding Secretary of the Ohio State [THIRD EDITION.] CINCINNATI: ROBERT CLARKE & CO., PUBLISHERS AND BOOKSELLERS. Entered, according to act of Congress, in the year 1861, BY ROBERT CLARKE & CO., In the Clerk's Office of the District Court of the United States for the Southern District of Ohio. THIS treatise is presented to the public as a brief dis cussion of the most important considerations involved in Land Drainage. The writer has not aimed to produce an original work, but has endeavored to collate well ascertained facts, and present them in as brief a space as the nature of the subject would permit. The productions of the best writers on the subject in Great Britain, France and Germany, as well as the current agricultural publications of this country, whether serial or otherwise, have been consulted in the preparation of this volume; while the numerous opportunities which presented themselves to the author, in fulfilling his duties in connection with the State Board of Agriculture, for observing the practical details of the work by visiting places where draining operations were conducted, tile manufactured, etc., have been cheerfully embraced, and the results embodied in the work. It may not be improper to state that the work was undertaken at the earnest solicitation of the Committee on Agriculture of the Ohio Legislature, during the session of 1858-9. The engravings were ordered and the greater portion of them finished before the appearance of Judge French's excellent work on the same subject; it was then too late to abandon the project. The work is respectfully submitted to the judgment of the farmers of the Great Northwest, in the hope that it may be found not altogether unuseful to them in their endeavors to improve their property. 299354 |
