The relation of the velocity to depth was deduced from hydro- 

 dynamical considerations, but its relation to distance from the coast, 

 which requires the determination of the function f(z) (equation 177, 

 p. 400), did not result from the foregoing reasoning, but will now be 

 considered. From equation (177), page 400 /(0)=:0 and f(z)= 1 

 as z increases, and for large values of y off San Diego, equation (185) 

 becomes

where (pp. 377, 388) W 1 = 31 meters per month where z equals 10 

 miles, and equals double that value or 62 meters per month, where 

 z equals zero. From page 363, for an average wind velocity of 15 miles 

 per hour or 7.5 meters per second
