Along the Xorth Atlantic coast Father Xeptune needs his heaviest guns, for the hard rock 

 cliffs of the coastline offer great resistance to the attacking sea 



the same relation to one another that they 

 did before. 



The geological history of the Panama 

 Canal region well illustrates how the 

 lands alternately subside and rise. On 

 the Atlantic side, the fact that the ancient 

 bed of the Chagres River is more than 

 ioo feet below the present land surface 

 was the principal cause of the fear in the 

 minds of some engineers that Gatun Dam 

 would not be stable. On the other hand, 

 not far from Panama City, there is a 

 beach where Indians formerly tied up 

 their boats that is now many feet above 



the surrounding water and some distance 

 back from the shoreline. 



The charting of the 20- fathom line 

 along the Atlantic coast from the Xorth 

 Carolina- Virginia boundary to Cape May 

 reveals the fact that if the ground were 

 to rise 20 fathoms or the sea to sink 20 

 fathoms there would be no Chesapeake 

 Bay and no Delaware Bay. The shore- 

 line between these points would be al- 

 most direct, with only very small, open 

 bays and peninsulas. The geological his- 

 tory of the Chesapeake Bay region, in 

 fact, shows that once there was no such
