MacMillan: SHORES at lake of the woods. 959 



B. Drier shores. 



1. Shores not easily wet by water or capable of rapid drainage. 



2. Shores unfavorably exposed to dews, rains and drifting snow. 



3. Shores protected against the deposition of surf and spray. 



4. Shores of which the outline, slope or exposure is unfavorable to the 

 deposit of ice floes in early spring. 



5. Shores from which the evaporation of moisture is promoted by ex- 

 posure to sunshine and atmospheric currents. 



H. Shores of which the texture favors the evaporation of rain, dew, 

 surf, spray, snow, ice or running water. 



TV. Classification of shores with reference to nutritive value. 



A. Nutritive shores. 



1. Shores, the components of which are rich in nutritive substances. 



2. Shores upon which waters, rich in nutritive substances, debouch 

 from streams or collect from waves. 



B. Sterile shores. 



1. Shores, the components of which are poor in nutritive substances. 



2. Shores upon which waters debouch or waves collect which are poor 

 in nutritive substances. 



V. Classification of shores with reference to atmospheric 



currents. 



A. Wind-swept shores. 



1. Shores exposed toward the quarter from which come the prevailing 

 winds. 



2. High or promontory-like shores. 



3. Shores facing wide expanses of water over which the wind has 

 greater sweep. 



4. Shores devoid of surface irregularities or growths of vegetation 

 sufficient to break the force of the wind. 



B. Sheltered shores. 



1. Shores exposed toward quarters from which prevailing winds do not 

 blow. 



2. Low or protected shores. 



3. Shores facing narrow expanses of water over which the wind has 

 not free sweep. 



4. Shores provided with irregularities of surface or growths of vegeta- 

 tion by which the force of the wind is broken. 



VI. Classification of shores with reference to mechanical 



effect of surf. 



A. Surf-beaten shores. 



1. Shores exposed to wide expanses of water resulting in more contin- 

 uous surf. 



2. Shores of which the slope affords greater impact-force to the surf. 



3. Shores exposed toward the quarter from which prevailing winds are 

 accustomed to blow.
