The contents of the following pages have been derived from a long course of art and technical training, together with a lengthened practical experience in textile manufacturing and designing; during which time I received much valuable assistance from many kind friends—especially Mr. B. Ashenhurst, when master of the Belfast Technical School, and his brother, of Bradford; also Mr. John Mitchell, of Belfast and Glasgow—which I thankfully acknowledge.

To supply a treatise that would be alike suitable to the manufacturer, the workman, and the student would be a difficult matter. To explain each point so fully that it would be clear to every person would make it wearisome to those having a knowledge of the subject. I have therefore endeavoured to keep the descriptions as concise as is compatible with a fairly clear explanation, which I hope will be considered the wisest plan to adopt; and, while quite aware of the many shortcomings of the work, I venture to hope that it will prove a valuable assistance to those wishing to improve their knowledge of jacquard weaving and designing.

T. F. BELL. Belfast, 1894.

It affords me much satisfaction to add a few words of introduction to this work of my friend Mr. Bell. I cannot pretend to criticise his explanation of technical processes, but, from an examination of the proof-sheets, I am convinced that the book will be found an invaluable aid to students of both art and technical schools. We already possess numerous text-books on designing as an art, as also on the technical processes of weaving, &c., and on the materials of manufacture. Mr. Bell has aimed at bringing the technical and artistic sides of the subject together in a practical form, and has thus provided us with a valuable handbook.

Though we have a Government Department of Science and Art, a knowledge of both branches is seldom united in the same individual. The artist is too often deficient in the science of his craft; while the man of science not unfrequently shows contempt for art. The author of this volume is peculiarly qualified for the task he has set himself, being a practical manufacturer as well as a designer of long experience, and thoroughly learned in the science of his subject. His book will supply a long-felt need.
