It Is Worth While to Know
It is worth while to know: The English soldiers were sent out to Tibet with ordinary open kettles for cooking and ordinary oil for lubricant. They did not know that at 15,000 feet above the sea, oil is no longer a lubricant, but a clog. They did not know that water boiling in an open vessel drops two degrees Fahrenheit for every 1,000 feet ascended. At the height of 15,000 feet water boils at 182°. This was not sufficient heat to cook food properly. Thereupon the men suffered. One Englishman points out that the cooking pots should have had air-tight lids, with safety-valves blowing off at a pressure of normal atmosphere at sea level, fifteen pounds to the square inch, and pure glycerine to lubricate the locks of rifles and Maxims. The suffering would have been saved. Facts in nature must not be ignored. Life and health come in harmony with the laws of life and health.
