August 6, 1921.
Following are some interesting facts and tidbits from 1921.
Cotton which has been put under hydraulic pressure of from 6,000 to 8,000 pounds and made into gears, produces an article superior to that made of steel. Softer than steel, the cotton gear yields where the steel gear wears under friction.
The two main ingredients in the manufacture of linoleum are cork and linseed oil, to which are added smaller quantities of Kauri gum, rosin and pigments of various kinds.
Clouds are very variable in height, from 500 to 2,000 feet. The clouds in thunderstorms may be very deep, from 2 to 5 miles and more, hence the appearance as to distance is very deceptive. Cumulus clouds are intermedate.
The strength of males increases rapidly from 12 to 19 years and more slowly and regularly up to 30 years, after which it declines. The strength of females increases at a more uniform rate from 9 to 19 years, more slowly to 30 after which it falls off.
When buying woolen materials hold them up to the light and look through them; the best qualities are free from uneven and broken threads.
There is still a prejudice among some against noght air. For that reason some foolish people sleep with their windows closed. Night air is not dangerous. On the average it is more pure than that of the day. In malarious sections exposure at night may be dangerous, not because the air is bad but because malarial mosquitos bite only at night. The danger is in the mosquito, not the air.
Absence doth but hold off a friend to make one see him more truly.
The world is not a playground; it is a schoolroom. Life is not a holiday, but an education.
Corruption in political life is really skepticism. It is a distrust, a disuse which has lasted so long that it has grown into disbelief of political principles, of the first fundamental truths of the sacredness of government and the necessity of righteousness.
Chilled hands or feet should not be put near the fire or in hot water, as this causes the blood vessels to dilate too rapidly and chilblains result. The chilled members may be put in tepid water and a little hot water added from time to time, but the best plan is to warm by excercise and by rubbing.
A person breathing cold air obtains as much oxygen in six inhalations as he would in seven taken in hot weather. This increase of oxygen is a matter of great consequence to sufferers from lung trouble and also to the person enjoying good health.
Patriotism, magical emotion, which makes you rise superior to all obstacles, support all weariness, willingly accept all necessary discipline and joyfully face all dangers.
