Show BIRTH OF THE MOON. Year by year the moon Is getting a few Inches more distant, and, reversing the argument, year by year. In the great past, the moon was nearer to us. Prof. George Darwin has shown that long, long ago the moon revolved close to the earth, and still earlier formed part of this globe. From that time to the present he calculates at least 54.-000,000 54.-000,000 years must have elapsed. The birth of the moon took place, therefore, somewhere about that date In the past. Sir Robert Ball observed that when the moon was near to us Its attraction must have produced enormous tides, many times greater than those that wash our shores today, and he suggested sug-gested that these tides, by their powerful pow-erful erosions and wasting of the land, accelerated the geological forces, and so reduced the tremendous periods which the geologists have demanded. |
