Excerpt from The Manufacture of Leather The manufacture of leather is now a chemical industry, and in this volume it has been the author's aim to treat it as such. The book is written for the general student of this branch of chemical technology, and an attempt has therefore been made on the one hand to keep the phraseology from being too scientific, in order that it may be intelligible to the intelligent workman, and on the other hand to keep it from being too technical in order that it may be of use to the pure chemist who wishes to apply his knowledge in the leather industry. On the technical side the author has endeavoured in his descriptions of practical methods to give prominence to those processes which are at present most widely used, but as the details of these processes vary so very much in different parts of the country and change so rapidly under the march of modern progress, it has been considered useless to enter into a minute description of them. At the most they may be taken as to some extent typical of what is employed in this country, and in no case is it claimed that the methods described will pro duce the best possible results. This is particularly true with regard to the finishing processes that are given. The reader who scans the later chapters of this book in the hope of dis covering new and wonderful recipes for seasons, finishes, etc., will search in vain. For the most part the recipes mentioned in the text are old and well known, and have been selected by the author merely from the standpoint of what was typical.

Excerpt from The Principles of Leather Manufacture In the eighteen years which have elapsed since the publication of the first edition, not only have great advances been made in the chemical knowledge on which the manufacture is based, but new points of view have been gained, involving an acquaintance with physical and colloidal chemistry which is not yet universal among leather-trade chemists, and I have felt compelled to enter into elementary details of these branches of science which, no doubt, in a few years will be among the commonplaces of chemical knowledge. I must therefore repeat the apology of the first preface, that to some of my readers much will necessarily seem too elementary, while to others it may prove too difficult, though I have endeavoured, as much as possible, to confine mathematical treatment to notes and appendices. It may be pointed out, however, that the advance of the future will necessarily tend to exact and mathematical methods, and that many theories which seem plausible enough when stated qualitatively and in general terms will break down when submitted to the rigorous examination of mathematics. The third volume on the Methods of Leather Manufacture, which was suggested in the former preface, yet remains to be written, but advancing age renders such a work impossible to the present writer, and its execution must be left to some of the young and well-trained chemists who are now devoting themselves to the trade. It is my pleasant duty to acknowledge much indebtedness to Mr F. C. Thompson, my Assistant in the Procter International Research Laboratory, not only for re-writing the chapters on the Chemistry of Hide and on that of the Tannins, with which he has made himself specially familiar, but for much general assistance both in the preparation of the work and in the reading of proofs; to Mr W. R. Atkin for his permission to insert the paper on hydrion measurement which appears in Appendix D, and also for help in proof-reading; and to the various gentlemen who have given information and allowed me to use their blocks and drawings in illustration; and especially to Mr A. Seymour-Jones, Professor McCandlish, Mr J. T. Wood, and Mr M. C. Lamb. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Manufacture of Leather: Manufacture of Leather, Parts 1-3 1. Definition and Classification. -The term leather is applied to the product obtained by the treatment of hides or skins of animals with certain reagents that convert the animal tissues into a tough, opaque, pliable, and fibrous substance which is not subject to putrefaction. 2. The pelts of animals come to the tanner in four conditions: green or market (fresh from the animal); green salted (when salt has been rubbed on the flesh and the skins placed in piles to cure); dry salted (same as green salted but afterwards allowed to dry); flint, or dry, hides (usually stretched and allowed to dry in the sun). According to their size, these pelts are divided into three general classes, namely, hides, kips, and skins. Hides comprise the coverings of larger animals such as the cow, horse, camel, and walrus. These are used for heavy leather manufacture such as shoe soles, machinery belting, harness, and other purposes where stiffness and strength are required. They are also often split for the purpose of producing shoe leather, bag, case, strap, automobile, and furniture leather. Kips are the undersized animals of the same species.

Excerpt from The Making of Leather The reader must therefore not complain if the ground covered is somewhat unfamiliar, but it is well worth exploring, since the explanation of some of the greatest problems of physiology and life undoubtedly lie in the same region.

Excerpt from The Leather Manufacture in the United States: A Dissertation on the Methods and Economics of Tanning The proprietor of the Shoe and Leather Reporter proposes to meet a very general demand for information in regard to the manufacture of bark tanned leather by grouping together in permanent form a series of articles on the subject, written for the paper by Mr. Jackson S. Schultz. To make the work acceptable to the tanners, not only of America but of foreign countries, it will be appropriately illustrated, presenting in outline, and in some instances in working drawings, the principal mechanical inventions employed in the business, so that the machines may be duplicated and the methods of their use easily comprehended. It was found inconvenient to illustrate the work during its publication in serial numbers, but now that it is to appear in book form that feature will be supplied, and will add to its appearance and usefulness. If the undertaking should be adequately encouraged by the tanners and finishers of bark leather, it will be followed at an early day by essays treating of "Sumac Tanning," and such other departments of leather and its fabrics as may be deemed worthy of consideration.
