TABLE VIII. Percentage Distribution of Wind Direction under 16 Points at the Winter Quarters of the 

 German Antarctic Exploration Vessel " Gauss," in Latitude 66 2' S., Longitude 89 38' E. 



TABLE IX. The Relative Frequency of Winds from each of Sixteen Points, and of Calms, observed 

 during Two Cruises of the "Scotia" in the Weddell Sea, in February and March, 1903, and in 

 March, 1904. 



From this table it will be seen that the winds blew chiefly from N.E., N., N.W., W. and S.W., and less 

 frequently from S., S.E. and E., but it is pointed out by Mr. MOSSMAN, in the paper from which this table 

 is derived, that "practically all the east winds recorded during the two cruises were experienced to the 

 south of the Antarctic circle," and also that the east winds were stronger than those from any other quarter, 

 from which it may be reasonably inferred that the wind distribution shown in the table was chiefly due to 

 the comparatively low latitudes at which the bulk of the observations were made, and that had the vessel 

 remained longer in the higher latitudes she occasionally reached, the easterly current would have been more 

 prominently exhibited. 



WIND CURRENTS AT HIGHER LEVELS. 



In one respect the choice of the " Discovery's " Winter Quarters proved to be an exceptionally fortunate 

 one, inasmuch as it afforded opportunities for obtaining information respecting the direction of motion of 

 the upper air currents by observations of the smoke emitted from the crater of Mount Erebus, nearly 

 13,000 feet above the sea level. 



Although the mountain was not visible from the ship it could always be seen, under normal conditions 

 of weather, from a short distance to the westward, and also from the observing station off Cape Armitage. 



On many of the sledge journeys, also, the smoke was visible, and it was the practice to include a note of 

 the direction of its drift along with the other meteorological observations. These sledge journey records
