Ocean Oddities.

The ocean at the depth of a mile has a pressure of one ton on every square inch. At the depth of 8,500 feet waves are never felt. If a box six feet deep of any size were filled with sea water and the same left to evaporate, there would be a layer of salt two inches thick left on the bottom of the box. Taking the nverage depth of all ooeaus to be three miles, there would be a salt stratum 230 feet thick over all the surface now occupied by oceans should the same evaporate.
