WOOL-CLASSES

Eleven students were present at the wool class at the Masterton Technical School last night, ami displayed a line interest in their work. The lecture

-was: "Yolk and its Kffeets on "Wool."

-Mr <„'. Bannister impressed the students that yolk acted an important part in Avoid growing, and- varied in. quality and quantity in different breeds, merino sheep producing the most. Although yolk was of a greasy, or fatty nature, it differed from all other fatty matter, being composed mostly of potash. It would dissolve in water, aud oven absorb half its own weight of water, was found in the greatest quantities - in the front half of the sheep ,aml through its agency the wool there was found to be the sounder. It acts as a. preservative to the fib re, ma Icing it soft and pliant. When in a healthy condition, it leaves a silky touch, but if the wool is devoid of yolk it will feel harsh and

unkind

In concluding his lecture, Mr Bamuster stated that in the wool'seou'ring industry of the Dominion the idea of saving yolk - seemed to be quite neglected. Tons wore allowed to run to waste, the only idea being to get rid of it. About half of the .0 per cent of shrinkage was pure yolk, so that from every lOOlbs of wool "L.ll . of this greasy matter or yolk could be saved. The •fat thus obtained was in some countries treated by a patent German method which freed it from all wax-like substances. Lanoline, which has such a high market value, was the result.

"Crimps and Serrations" will be the subject of next week's* lecture.
