Prop. II. — It is required to calculate the effects of the Kuro-Siwo (Japan 

 current) upon climates in the North Pacific, and its effect upon high latitudes, 

 if it were admitted to the Arctic Ocean through Behring Strait, luidened 

 and deepened. 



Following the same method that I have used for the Gulf Stream, I 

 find the effects of the Kuro-Siwo in the North Pacific to he as follow : — 



North Pacific. Mean July Temperatures. 



This table shows that the summer effect of the Kuro-Siwo upon the 

 North Pacific is even less than the summer effect of the Gulf Stream upon 

 the North Atlantic. The reason of this is, that although the Kuro-Siwo 

 is a much larger current than the Gulf Stream, it is required to heat a 

 much larger area, for the North Pacific is much larger than the North 

 Atlantic. 



The effects produced in winter by the Kuro-Siwo are shown in the 

 following table : — 



' This represents the effect of the portion of the Kuro-Siwo which enters 

 Behring Strait in summer, and extends eastward as far as Banks' Land, but is 

 unable to enter in winter.
