Book Description
Excerpt from Land Drainage: A Treatise on the Design and Construction of Open and Closed Drains To young and inexperienced drainage engineers: Especial efforts have been put forth through the medium of these-pages to acquaint you with the problems that you must meet; to impress upon you the importance of accuracy, judgment, hon esty and diligence in the investigation and solution of these problems, and to suggest methods of procedure under average conditions and the general principles upon which to base conclusions and plans. To experienced drainage engineers: The author hopes for a careful and analytical reading of these pages by you and that some of you will be thus incited to take issue with or elaborate upon the questions discussed and thus aid in the formulation of better drainage standards. To drainage contractors: The author has recognized the facts that contractors have been compelled too often to contend against such unfair conditions as incomplete surveys and reports; the framing of specifications so as to burden con tractors with the risks resulting from insufficient plans, and treacherous soils and unfavorable weather conditions, and has pleaded for justice and equity to contractors. Neither have the faults and obligations of contractors been overlooked. Also information is included which will prove useful to contractors, and it is suggested that a general study of the subject of land drainage would better enable contractors to protect their rights and succeed in their business. To land owners and drainage district officials: The author believes that a general understanding of land drainage science by you would enable you better to distinguish between the efficient and the incapable in employing drainage engineers and to assist and advise with them in the direction of the work which is of such great importance to the agricultural interests of the United States and thus accomplish more effective land drainage. In conclusion, this treatise has been made as complete as possible for the subjects connected with the successful drainage of agricultural lands by open and closed drains. The author hereby acknowledges a large amount of valuable information which has been gleaned from the reports of the United States Department of Agriculture, from reports of state and other col leges, from the reports of engineering societies, and from engi neering periodicals. Specific reference has been made in all cases where important data have been reproduced. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Drainage Engineering The purpose of writing the following pages has been to present a general treatise on the drainage of agricultural lands. An attempt has been made to outline the various questions that should be considered in taking up a drainage problem, and to put into brief but comprehensive form the principles involved in the design and construction of drainage works. The activities of the past few years intended to increase and improve agricultural areas through drainage, have greatly enlarged the application of engineering and scientific studies to this character of work. In addition to unwatering and re claiming natural swamp and overflow lands, of which there are many millions of acres, principally in the humid sections of the United States, large drainage problems have developed and are still developing in the arid regions, as a result of irriga tion. It has been estimated on irrigated lands generally that about one-fourth of the total area becomes unfit for profitable cultivation unless protected by drainage. As a branch of Engineering, drainage presents many interest ing and difficult problems. On account Of the many varied and uncertain factors relating to soil and ground water conditions, it is diffit to formulate general laws governing many features Of it. Each particular problem requires special study for economic and efficient results. The subject involves a study of the soil, hydrographic conditions, and also the location, design and construction of waterways for carrying away the excess supply. The effect of drainage upon the soil embraces questions of agriculture and soil physics. In every drainage enterprise economic questions are also involved. The principles and methods I have endeavored to outline have been slowly developed through many years - even centuries. It is impossible, in most cases, to determine to whom the credit for them belongs. I have attempted, where possible, to give appropriate references throughout the text. Acknowledgment also is made to all whose writings I have read, to engineers whose cooperation I have had in working out drainage problems, and to many friends who have kindly assisted me in the work.

Book Description
PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...

Book Description
Moisture control is fundamental to the proper functioning of any building. Controlling moisture is important to protect occupants from adverse health effects and to protect the building, its mechanical systems and its contents from physical or chemical damage. Yet, moisture problems are so common in buildings, many people consider them inevitable. Excessive moisture accumulation plagues buildings throughout the United States, from tropical Hawaii to arctic Alaska and from the hot, humid Gulf Coast to the hot, dry Sonoran Desert. Between 1994 and 1998, the U.S. Environmental Protection Agency (EPA) Building Assessment Survey and Evaluation (BASE) study collected information about the indoor air quality of 100 randomly selected public and private office buildings in the 10 U.S. climatic regions.
