���Much of the danger of driving on snow is eliminated by the

use of these skiis on the front wheels. They travel lightly

over the snow, and by responding promptly to the wheel

make skidding less likely

��Motoring on Skiis

MOTORISTS who know the diffi- culties and dangers of piloting their cars through heavy snow, will greet with approval a new device which is claimed to make snow-driving safe, prac- tical and comfortable.

Two kiln-dried white ash skiis are fas- tened securely to the front wheels, and carrv them over the surface of the snow. In deep snow the full width of the skiis carries the load, while on a hard path only the steel guide runner touches the road. The guide runner also makes steering easy and prevents the skidding of the front wheels.

Does Your Child Suck It's Thumb?

IT is very seldom that we see a straight, well-formed mouth. Sometimes it is spoiled by protruding teeth, sometimes by a large overhanging upper jaw, gen- erally we find the upper lip much larger than the lower. This is not. as might at first be supposed, a characteristic of the American people just as flat noses are a characteristic of the Negro race.

��It is due to one of the most unfortunate habits that can be formed in childhood — the sucking of the thumb.

The bones of a baby's jaw are extremely plas- tic, and subject to al- most any amount of de- formity by long-contin- ued impact and strain. If even as soft an object as a thumb is placed in the mouth for any length of time, the inevitable re- sult will be that the up- per jaw and the teeth will be pushed out of place.

Many mothers are aware of the dan- ger in making such a habit, and they resort to what they think is the next best thing — which is in reality the next worst thing — the pacifier. Imag- ine a bit of hard in a child's mouth waking hours, and

A child should not be permitted to carry any object in its mouth aside from the rubber nipple of its bottle, and even here care should be taken to see that this is removed prompt- ly after the feeding is over.

It is not easy to prevent the baby from putting its fingers into its mouth, as this is more or less of a natural in- clination. In rare extreme cases it is necessary to tie the hands. Many par- ents put a bitter solution on the fingers which is sufficiently distasteful to break up the practice, but this is a doubtful procedure and one to resort to only by the advice of a physician.

PENNSYLVANIA leads all other states in the country in the use of steam power, using twenty per cent, of all that is used in the entire United States.
