of the ocean currents as factors in determining the climate 

 of our State. 



Furthermore, they prove the advisability of our Govern- 

 ment, through its branch the Signal Service, continuing 

 this research. The isothermal lines of the ocean for differ- 

 ent months at different distances from shore and along the 

 -entirewest coast of the United States, should be established 

 beyond doubt. They will form the constant factor for the 

 calculations of our meteorologists. They will probably 

 explain the formation of our barometric maxima and 

 minima, and will enable us to make weather predictions 

 with more accuracy than it is possible to do without them.
