Excerpt from A Treatise on the Design and Construction of Mill Buildings: And Other Industrial Plants This book is the outcome of a smaller one entitled Mill Build ing Construction, written in 1896 and given to the publishers in 1900. These books are based on the personal experience of the writer, covering a period of twenty years in designing and esti mating buildings, bridges and other structural work, and most of their contents is from his private notes and records. A separate part on The Theory of Economic Design was included in the present work because of the large amount of capi tal being invested in manufacturing plants. A knowledge of the possibilities and requirements should precede the design, and it is only by the exercise of such knowledge that the best results are Obtained. The introduction of Part I has caused some repetition, as subjects discussed generally in this part are treated more fully in Parts III and IV on details. The repetition, however, seems necessary for clearness, as the whole contents of one part would be out of place in the other. This is particularly the case in the chapters on framing of northern light and other roofs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
