over each other, and then thoroughly teased until a 

 uniform blend is obtained. 



From this point onward the process of manufacture 

 is practically the same for wool as for cotton. The 

 various spinning-machines and looms are practically 

 the same, modified in details for certain purposes, and 

 need not be considered separately. The story of the 

 development of these machines centers about the cot- 

 ton industry; but what is said of the manufacture of 

 this textile applies equally, with certain modifications 

 as to details, to the sister textile as well. We may 

 note here, however, that wool is habitually worked into 

 two quite different types of yarn, known respectively 

 as "worsted" and "woolen" yarn. In worsted yarns 

 the fibers are long and lie nearly parallel with one 

 another, so giving the material a smooth surface. The 

 fibers of woolen yarn, on the other hand, lie in all 

 directions, with many loose ends projecting so giving 

 a rough surface. But cloth woven from these rough 

 fibers, when felted or milled, presents a smooth and 

 even surface, concealing the individual threads, owing 

 to the interlacing of the individual fibers during the 

 milling process. The difference in texture between 

 worsteds and woolens as presented in the finished goods 

 is familiar to every one.

For over a century England has been the center of 

 cotton- and wool-manufacture of the world; the revo-
