Age of the Oceans.

Scientists have figured out the average amount of salt carried by the-, rivers of the world as a total, and have compared with the total quantity of salt in the oceans. From these data (taking into account evaporation and rate of stream flow), it is.possible to reckon how many years have been required to make the seas as salt aa they are today. On this basis. Prof.' Frank Clarke of the United Stales geological survey, one of the foremost authorities, estimates that the ojeana are about 90,000,000 years old.
