Book Description
Excerpt from d104-Book of Land Drainage The low yields of farm crops in this country are frequently used as a basis for speculation as to the future limit of food supply. The causes for these low yields are variously estimated. Bad management, over-cropping, loss of soil fertility, washing away of soils, "changing climatic conditions," and even "over-drainage" are among the more prominent of the causes named. "Bad management" is a very comprehensive term. "Loss of soil fertility" is a much used expression, but indifferently understood. Sometimes it is properly applied, but in many cases it probably does not apply except in so far as it may be synonymous with malnutrition of the crop. The improper functioning of common soils, because of the extended presence, at some time during each year, of excessive amounts of water, is seldom mentioned; and yet one needs but to travel through the land with an observant eye in the cropping season to discover areas (even in the so-called "garden spots") where half stands exist, fourth stands, and actually no stands for a half field or whole field, indicating failure in germination or very soon thereafter. He discovers sickly full stands, half stands and less; also drowned areas, and places where no crops have been planted -"skipped areas" - in fields that in other parts have a thrifty appearance of crops. It is difficult, indeed, to estimate the losses resulting from such conditions. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

Book Description
Excerpt from Notes on Drainage: Class Room, Field, and Laboratory Exercises for Students of Land Drainage Drainage is vitally concerned with the difference in elevation between points on the area in question. The distance through which this fall is to be distributed is another factor. Then too, the extent of the area to be drained must be considered. This is the first step in the reclamation of broad expanses of marsh lands, un touched perhaps by all save the original survey, accord ing to which the sub-division was made. Old section corners must be located so that correct descriptions can be obtained, of all parcels of land to be included in the proposed drainage district.

Book Description
Excerpt from Engineering for Land Drainage: A Manual for Laying Out and Constructing Drains for the Improvement of Agricultural Lands Land drainage in this country has had its principal growth during the last twenty years. Its practice reaches from the simple drainage of a garden costing only a few dollars to that of tracts containing thousands of acres, involving elaborate plans and the expenditure of large sums of money. It includes the drainage of all kinds of lands which require it, either for profit or for health, and hence embraces a wider range Of topics than, upon first thought, seems to be involved.

Not illustrated. 1916 edition. Excerpt: ...drain, as described in paragraph 146, excepting that the laterals discharge at their lower terminal into the main or sub-main, and not at an outlet. It is most convenient to drive the grade stakes at intervals of 50 feet, for reasons given in paragraph 147, and for the further reason that a greater distance than 50 feet increases the difficulty in using the boning line. 154. The angle of approach for laterals.--It is common, in systems like that illustrated in Fig. 25, to locate the laterals so that their upper angle to the main shall be less than 90 degrees. If, however, it should be deemed advisable to run the lateral at right angles to the main, as shown in Fig. 26, then they should be turned slightly as they approach the main so as to enter at an angle of less than 90 degrees, the reason being that if the water from the lateral is discharged into the main at an angle of 90 degrees, it is likely to interfere with the movements of the water and also with the ready movement of the silt which may be carried by the waters of the main. Another factor, however, that must enter into the angle of approach is the position and shape of the area requiring drainage. (See Figs. 28 and 29.) The angle of approach must be determined by the needs of the land and economy i in labor. The angle of discharge should be governed by the suggestions above. 155. The location of the upper end of mains and laterals.--It is not necessary to carry the end of either main or lateral to the very edge of the area to be drained. The water in the soil will move toward the end as readily as it will toward any other point in the drain. The line of equal influence of the drain at this point is the arc of a circle whose center is the end of the drain. 156. Measurements.--Due...
