leaving and entering port. The general set of the shore 

 currents has an effect upon the position and shape of 

 these inlets, deflecting the openings in the direction of 

 their flow. They may also singularly modify the outlines 

 of the reefs themselves as in the formation of the three 

 much dreaded capes off the coast of North Carolina. 



144. Depressed Coast. Experiment 127. Cover a small board 

 with a piece of thin oilcloth which has been most irregularly crumpled. 

 Take the board by one edge and inclining it slightly gradually sub- 

 merge it in a dish of water. What kind of a line does the water form 

 where it meets the oilcloth ? In what way would this line change if 

 the oilcloth were more crumpled? If it were less crumpled? If the 

 board is more submerged, does the position of the water line change ? 

 Why does its form materially alter? 



PART OF THE COAST OF MAINE. 

 A fine example of depressed coast. 



Along a coast which has been depressed, the shore line 

 has moved landward and a surface rendered irregular by 

 erosion is lapped by the inflowing water. All the ir-
