Water Treasure and Temperature.

The pressure of water at the average depth of the ocean—two miles—is about equal to that of 320 atmospheres, that Is to say, 4,800 pounds to the square Inch. The temperature of the atmosphere cools, on an average, about one degree for every 300 feet that we ascend, or warms at the same rate as we descend. The mean temperature at the north polo Is about 0, and at the equator between 80 and 90 degrees. We can. therefore, get into a temperature one degree colder for every 70 or 80 miles that we travel north, or In a temperature one degree warmer for every 70 or SO that we travel south.
