Some time ago there were in- dications that special valves for working from a source of relative ly low voltage would be intro- duced. These special valves were to be of the four electrode type, but apparently the manufacturers who were experimenting with these valres decided that the de- mand would not justify them in by the output transformer, which placing the valves on the market has the loudspeaker connected to for very little is heard of them it. nowadays.

DISAPPEARING SCRUBBING

BRUSH.

"Before two years have passed I hope such a thing as a scrubbing- brush will not be known in our schools," said Mrs. Wilton Phipps at a meeting of the London County! Council Education Committee, an- mauncing the result of the oil treat- ment of the floors of schools. "Or course I am old-fashioned, and I have a preference for the scrubbing- brush, but I have frankly to admit that the new method of cleaning has made a great deal of difference to both scholars and teachers."

The method had been extended to 100 additional schools, and had been used in 571 departments in 218 elementary schools. Extension of the treatment would ultimately effect a saving of about $4,000 a year. The experiment had been a very great success. The teachers] were pleased with it, and the medi cal officers gave them very great. encouragement concerning it.

Mr. Manning, supporting, said || that if 25,000 a year was to be saved by the adoption of the oil tatment of school floors he would prefer that the money saved went on to the wages of the women whom they had to employ,

The amendment was defeated and the report, which recommend ed that the scale of assistance to 'school keepers for cleaning; should abe reduced by two-thirds at schools where the floors were olled for Polished wit
