Book Description
Excerpt from Land Drainage by Means of Pumps In constructing diversion ditches the experience of the Coal Creek District should be kept in mind and ample provision made for the deposition of silt before it reaches the diversion channel proper, otherwise the usefulness of the latter will be of very short duration. Even when silting basins are provided it Should be remembered that they will eventually become filled, and they should therefore be so located that other basins can later be constructed to receive the silt from the'same stream without incurring needless expense due to the improper location of the first basin. Local conditions will deter mine the plan to be followed, but the subject merits the most careful study. While in this country work of this nature is just starting, in England and Holland diversion ditches to prevent drainage water from flowing from higher lands onto lower areas, to the great damage of the latter, have been in systematic use for a long time. If the levees are properly constructed, as heretofore explained, the amount of seepage water passing under them is ordinarily so small as to be negligible, but if the soil or the subsoil of the district be very sandy, or if the levees have been carelessly constructed upon an improper foundation, the seepage may accumulate in sufficient quan tity to be troublesome. Ordinarily, if land near the levee is injured by seepage, the difficulty may be corrected by laying a line of tile parallel with the levee and 50 to 100 feet from the toe of the s10pe.

Book Description
Excerpt from Mine Drainage, Pumps, Etc Dear sir: In pursuance of your instructions, I have prepared this Bulletin of the State Mining Bureau, treating of the most important applications of water-raising machinery for the drainage of mines. It has been my aim to make this a short, popular exposition of methods, constructions, and principles involved in the machines used in the extremely varied conditions of mining on the Pacific Coast and, in view of the modern improvements and facilities in the transmission of power, which may make advantageous the use of machines not now employed in mine drainage, these have also been given consideration. The amount of ground covered in the treatment of each subject has necessarily been limited. The principles governing the design and Oper ation of apparatus have, however, been given at some length, in order to render them clear. Only where absolutely necessary has use been made of mathematical expressions, and these most simple. The old Cornish and other non-rotative engines applied to the so called Cornish system, which are to-day practically obsolete, have received only the brief notice due from the standpoint of historical reference, and where necessary to explain motives for improvement of methods. As akin to the general subject, water-raising machines applied to other uses than mine drainage are incidentally mentioned; and in an appendix will be found some remarks on the appliances used in irrigation and land drainage. Among the difficulties encountered in preparing a work of this nature, and which cause delay in its completion, are those of obtaining correct data with reference to the practical working of apparatus, and recon oiling contradictory statements of results.

Book Description
Excerpt from Land Drainage This book deals with the subject of drainage primarily from the agricultural standpoint, and the subject has been developed largely as a matter of applied soil-physics. Drainage is considered herein as a means of reclaiming additional areas and of making wet lands more productive. Reclamation of arid and wet lands affords the chief means of increasing our food producing areas and drawing a greater proportion of our population into the rural districts. The present volume is intended, first, as a text book for students of general agriculture or agricultural engineering; second, as a reference book for practical farmers; and third, as an aid to owners of wet, overflowed, marsh, swamp or alkaline land who desire to improve their holdings. The information presented herein has been gathered by the authors, as farmers, students and instructors, in the Corn Belt States and later in the West, where preliminary feasibility surveys and selection of lands for irrigation projects and drainage projects have been an important feature of our work. Review questions, general references and laboratory exercises have been included to help make up the kind of a book that has seemed to the writers to be needed.
