The winter is not uniformly cold throughout. 1'eri-nK of low 

 temperature become longer and more intense until midwinter, after 

 which they decrease gradually until spring. These cold period- of 

 '.wo or three days' duration are due to north winds, and are always 

 moderated by a change of wind. A warm south wind now and 

 again causes a thaw, and a portion of the -now disappears. SO that 

 an e umulation of snow is u-ually prevented. These 



variation- are not 50 marked in the north, and its climate is more 

 c< (liable. 



The direction of the wind, as so far indicated, governs the cli- 

 mate to a great extent. Winds from certain quarter- greatly influ- 

 the seasons in their variation from each other. The prevail- 

 ing winds are from the west. As they pass over the Great I 

 their coldness is moderated in winter and their heat in summer. 

 Hot wind- from the south are similarly tempered. Damage from 

 wind storms is uncommon. 



The Great Lakes have an influence apart from altitude, altl 

 the latter has a minor effect. They remain comparatively warm 

 during the winter and ha\ : in tempering the climate 



of places on the shore* than of tho-e inland, the diffe
