PREFACE. THE sole object of the chapters comprising this volume is to give the reader a general view of the principles which underlie the several manufactures described. It is in no way intended to present such an account of details as will suffice for the student of any particular industry, as indeed must be obvious from the size of the book. The usefulness with which the authors venture to accredit their work is to be found in the fact that it seeks to expound those dominant principles which are too often hidden beneath masses of mere detail, and are consequently apt to be overlooked by the specialist in any one branch, to his detriment, in that he frequently fails to apply to his own work principles which are matters of common knowledge elsewhere. These remarks are rendered necessary by the fact that the scope and intention of the first volume of this book appear to have been occasionally misunderstood. The Bibliography, which will be found at the end of the work, will serve to indicate the sources of information which are at hand for those who desire further details on any particular subject. In this volume the authors have had the able advice of Mr. Geo. H. Hurst concerning the technique of Bleaching and Dyeing, and they take this opportunity of thanking him for his valuable assistance.
