An International Correspondence Schools instruction paper on preparing and scouring raw wool in the mill. It covers dusting machines (cone, square and open dusters), the impurities in grease wool such as yolk, suint and dirt, and scouring agents (soaps, soda ash, potash), with tests for caustic alkali and adulteration. It also treats water hardness and softening, the effects of improper scouring, scouring machines (rake, parallel rake, hydraulic washers, squeeze rolls, self-feeds), naphtha degreasing, and the use of thermometers and hydrometers, ending with a Baumé–Twaddle comparison table.
