To continue the study, I analyzed the drift of the Sedo u from 1 September 1938 through 

 1 January 1940, i. e. , the period when the Sedo u was over great ocean depths and far from the dis- 

 torting influence of the coast. During that time, 5764 measurements of wind speed and direction 

 were made on the Sedou . In the analysis, I found that I could use 378 drift segments included be- 

 tween complete astronomical determinations and that I could calculate the resultant winds for these 

 segments. 



In processing this extensive material I found that the wind path often intersected itself. This 

 allowed me, using Nansen's method, to calculate the elements of the steady current at various 

 regions of the drift. First of all, I became convinced that the drift velocity is a linear function of 

 the wind speed.
