cheerless waste, as it does over the frozen lakes 

 and seas, carrying cold and dryness to the south. 



We can now without difficulty explain why the 

 lowest mean yearly temperature, and the coldest 

 winters, must be found especially in the inland 

 parts of continents, why their position with regard 

 to the sea, and the direction of their winds, have 

 almost as much effect upon the climate of the 

 countries in the far north, as the slanting direction 

 of the sun's rays, and the length of its winter 

 absence. It is clear, too, that in the coldest 

 regions of the earth every wind must bring warmth 

 with it, and that the severest cold can only occur 

 when the air is still.
