removed by a process known as breaking. The straw is 

 either pounded with wooden mallets or bent in some sort of 

 machine, but the best quality of fiber is obtained when the 

 work is done by hand with mallets. Any coarse fiber, bark, 

 or wood which remains is removed by a process known as 

 scutching, which consists of beating the bundles of fiber with 

 a series of paddles. This is sometimes done by hand, but 

 usually by machinery. . The fiber is then sorted according 

 to its quality and baled into bundles of about 200 pounds 

 each. It is kept in these bales until it is spun into thread 

 and woven into cloth, either alone or in combination with 

 cotton. Some of the finest laces and fabrics are made from 

 linen thread. The coarser fiber, or tow, is used in the manu- 

 facture of twine and in upholstering.
