Tlie west coast of Hollanfl from the northernmost outlet of tlie Rhine to Helder 

 at the uilet to the Zuyder Zee (Atlas Univ. 26; Holl., 14, 19, 24, 25, 30, 37). Tliis 

 is a porti'^n of tlie confluent delta of the Rhine and adjacent streams. 



The coast of Belgium (Alias Univ., 25; Belg., 4, 5, 11, 12, 19). 



Depressioii : Youth. — Southwest Ireland is a typical example of youthful shore 

 evolution upon a vigorous coast (Ireland, 150, 151, 160, 161, 162, 171, 172, 17o, 182, 

 183, 184, 190, 191, 192, 197, 198, 199, 203, 204). A region of strong relief, with 

 transverse trends, dissected to about early maturity, was deeply drownt'd and 

 exposed to the strong attack of the open sea. Far up into the bays the waves 

 attack the coast and the offshore currents carry away the waste from tlie jagged 

 cliffs. Grade is reached only in the bay-bars near the heads of the bays. 



The southern coast of Curzola island (Austr., 34, XVI). 



The west coast of Central America, San Juan del Sur to gulf of Nicoya (II. 0., 

 1016, details in 1025-1034). 



Soledad bay and Santo Tomas anchorage. Lower California (II. 0., 1044). 



Port Islay, Peru (H. 0., 1183). 



Brayza island, Austria (Austr., 32, XV). 



Meleda island, Austria (Austr., 34, XVII). 



The southernmost portion of the Austrian coast, in places becoming adolescent 

 (Austr., 3(i, XIX ; 37, XX). 



Many portions of the coast of Greece (Attica, III, VIII, XVI, XXI, XXII, and 

 XXIII). 



The youthful shoreline of the low coast of Saitiiolm is markedly contrasted with 

 the adolescent shoreline north and south of Copenliagen (Denm., Kjilbenliavn). 



The eastern coast of Schleswig (Germ., 7, 13, 14, 23, 24). The development has 

 advanced to adolescence in many of the more exposed portions of this low coast. 



The steep eastern coast of Sweden from Ilanil Bay northward to a point on the 

 mainland opposite the north end of Gland island (Swe., 6, 10, 11, 12, 17, 22, 29). 

 It is worth notice how sligiitly the glacial accidents have here modified the forms 

 due to drowning. 



The Stockholm district (page 159). 



The irregular cliffs of eastern Scotland indicate yonth'"iil shore evolution (Scot., 

 57, 67, 77, 87).* The development has gone a little farther toward adolescence 

 near Rattray head (Scot., 97), but very jagged cliffs are seen to the west of this 

 head (Scot., 95, 96). The north coast of Scotland (Scot., 113, 114, 115, 116) shows 

 almost no transportation alongshore, althougli several bays have been partly filled. 



The west coast of North and South Uist (Scot., 08, 69, 78, 79, 88, 89) shows 

 a nearer approach to adolescent simplification of outline than their irregular 

 eastern coast. 



Taken as a whole the western coast of Scotland, where the sea attack is stronger 

 though the rocks are more resistant, is nearer adolescence than the eastern, where 

 the weaker attack of the North sea has not done so much work upon the less meta- 

 morphosed rocks. The time since the beginning of the present cycle may not have 

 been the same in the two areas. As the division lines have been drawn in this 

 scheme, this Atlantic coast of Scotland is about on the border between the two 

 stages. Youthful and adolescent features both occur. Two typical areas, from
