BREAKING AND SCUTCHING. The care exercised in growing and retting a flax crop must be supplemented by the skill of the mill- worker in breaking and cleaning it. The operation of removing from the fibre the ligneous or woody part of the straw commonly called shives is the test by which to judge the effectiveness of the preparatory operations. Properly retted flax of good quality gets rid of a great deal of its woody shive dur- ing the operation of breaking. If under-retted, the shive clings to t...he fibre, and the resultant excessive use of the scutching knives causes an excessive amount of tow and breaking of the fibre. If the shives cling to the fibre in places after the scutcher has done his best, the value of the flax is considerably reduced. Over-retted straw and short mixed in a handful fall into waste at every application of the knives. Moreover, wastage is easily caused on good flax when either the break hands or the scutchers are careless or unskilled. As the function of the breaks is quite as much to reduce the wood into shive uniformly as well as finely, it is important that the man who feeds the break spread the flax out evenly.
