The resultant direction and its amount are shown in the last line. The 

 prevailing winds are chiefly easterly. The station lay on the north side of 

 the Atlantic barometrical trough (p. 572). 



The mean velocity of the wind is estimated a little less than the measured 

 velocity at the Fram (p. 309). 



Gales with estimated velocities of 15 metres per second and upwards to 

 18 metres were experienced on two days in December, on two days in January, 

 and on one day in February. The highest velocity measured at the Fram 

 was 18 m. p. s. (p. 310). 



In order to see how the observations at the winter-hut stand in relation 

 to those of the Fram and at Cape Flora i (Lat. 78° 55' N; Long. 48 "40' E), 

 I have put together the following Table.
