About the middle of theeighteenth century machinery for spinning yarnsbegan to lie improved so that there came a de-mand for an improved loom: the result was theproduction of a power-loom in 1785 by Dr. Ed-mund Cartwright, which came into successfuloperation in weaving-sheds or factories in theearly part of the nineteenth century. The de-velopment of the industry has been attended bygome of the most wonderful mechanical inven-tions. The result is the automatic productionby machinery of fabrics rivaling if not surpass-ing the most elaborate and costly made by handwith far greater rapidity and a greater degreeof perfection. Weaves. While there are innumerable ar-rangements, called iceaves. for the interlacing ofthe warp and filling threads in weaving varioustextile fabrics, these arrangements are all basedon three primary weaves, illustrated in Figs. 1,^, and 3, technically called the plain, ticill, ami.
