that side. At the same time less rapid erosion is taking place on 

 the west side under the action of less violent waves. 



CONCLUSIONS. 



In conclusion, it may be stated that the forelands here described 

 seem to have been built wholly by the action of waves acting 

 either directly or indirectly in association with longshore cur- 

 rents which were intimately associated with them. 



The location of the forelands is associated with some more or 

 less salient feature of the coast which has influenced the direc- 

 tion of wave advance and the course of longshore currents, and 

 has localized the effective transporting action of both. 



Their formation is due to the control exercised on wind 

 direction and on wave direction by the form of the bay. The 

 form of the forelands is due to the peculiar character of the long, 

 narrow water body on which they are situated, the conditions 

 being such that only certain classes of storms can be effective 

 agents in the shore transportation. The immature character, and 

 consequent imperfect adjustments of sub-acqueous portions of 

 the shore is an important control in wave-work. 



The V-terrace and the associated V-bar upon it, in the instances 

 here studied, are regarded as products of the same agent, and 

 do not necessarily imply a change in water level. The evidence 

 from Point Pleasant spit implies that there has been no signifi- 

 cant change in level during the long period of growth of the 



greater part of the spit.
