Show The Old and New Way ol Scouring Wool. Our ancestors scoured their wool in tubs, much as our wives and daughters scour our clothes today. In the hand washing of wool, a tub was filled with the suds, m which one or two men with long poles stirred the wool until clean, when they lifted it upon a traveling apron, which carried it between a pair of rollers which squeezed out the water. The same principle is applied in the automatic au-tomatic scouring now in vogue. Great forks or rakes seize the wool as it is carried by rollers from a feeding apron into the iron tanks, and by alternating alter-nating motions of their teeth give it a thorough scouring. Thus cleansed, the wool is delivered by rollers to the drying dry-ing machines, where hot air and great fans are now utilized to extract all the moisture without tearing the fiber. 3. N. D.
