INTRODUCTION. 



Although considerable attention lias been paid to the question 

 of ocean currents off the west coast of the United States, yet 

 much work remains to be done, that accurate information as to 

 the limits, direction and temperature during the year of the 

 various streams or drifts may be ascertained. The Pilot Charts 

 of the North Pacific, issued monthly by the United States Hydro- 

 graphic Office, give for each of the four seasons a somewhat 

 schematic current chart which is virtually a composite of the 

 observations received by that office. Upon the face of each 

 sheet there is a statement printed in red, calling attention to the
