HEAT AND COLD. 



the same time act from south to north, so we will not 

 be likely to have any trouble in tumbling from north 

 to south or vice versa. It requires heat to disperse the 

 frozen properties in each of these zones, and as long 

 as the heat is not forthcoming there is no danger of a 

 change in the zones. 



Now we will consider how the sun, aided by cold, 

 causes the ocean currents as an accessory to the revo- 

 lution of the earth on its axis. The sun acting with its 

 repelling force easterly, causes the water to impinge 

 against the adjacent continent, or coast line of same. 

 Then the waters become deflected by the outlines of the 

 continents in conformity with the general trend of 

 same. When deflected it becomes aided by the cooling 

 action of the zones of cold in which it has been forced 

 by the original power of movement. The water enter- 

 ing a zone where the tendency of the water is in the 

 range of cohesion, it in consequence must be caused 

 to move faster until the margin of expansion has been 

 reached in the body. When the water has been de- 

 flected south by continental outlines it is aided by the 

 cooling action of the cold until the point of expansion 

 has been reached in the body of water. The excess of 

 flow that continues beyond the margin of the expand- 

 ing in the southern waters becomes deflected from the 

 southern ice banks and is further aided by the propell- 

 ing power of the sun easterly until again affected by the 

 continental outlines, against which it again impinges. 



Let us take observations on the action of the sun
