Practically all the original matter is reproduced in this edition; any small parts which have been omitted have been replaced by illustrations of more modern machinery. The additional matter embraces 108 new illustrations with the corresponding text; it includes the two distinct types of automatic weft supply mechanism, the chain linking machine, terry towel motions, warp stop motions, indi vidual motor drives, improved types of box motions and jacquards. In nearly every chapter there has been inserted one or more new illustrations of modern weaving machinery. We desire again to express our best thanks to all those who have been kind enough to assist us in this work, and to the publishers and printers for the excellent manner in which they have done their part.
