cycle. In the first area the land is supposed to have risen with respect 

 to the water far enough to bring all the features of shore development 

 of the previous cycle above baselevel ; while in the second area these 

 features are depressed beneath baselevel. Criteria are worked out for 

 these two normal or average conditions, and later other possibilities will 

 be considered in connection with actual regions. 



2. Uniform Uplift. 



Initial Stage of an Ideal Area. — Let it be conceived that a region be 

 elevated as a unit to a certain distance above sealevel. The geologic 

 cause of such uplift need not be considered here, as this paper treats of

 Elevated Former Shoreline, and the Dissected Oldland.
