JULY, 1911 continued. 

 July 17th, 1911 continued. 



The sky gradually cleared. A N.W. wind blew again for a couple of hours this 

 evening and the weather became very thick, Cape Adare almost disappeared, and spicular 

 snow fell again. The barometer is steady and the temperature high. 



12 midnight, The sky has cleared, but for Strato-cumulus on the Northern horizon and a 

 bank of cloud on Cape Adare. Calm. Temperature falling. 



July 18th, 1911. 



4 a.m. Calm. Sky remains clear. Glaciers cleared since 2 a.m. Barometer steady and 

 temperature falling. 



10 a.m. Calm. Clear. Temperature fallen considerably. Clouds moving from the N.N.E. 

 and banking up in the N. Barometer steady. 



10 p.m. This morning heavy whirlwinds of drift were observed on the sea ice to the N.,but it 

 remained calm here. It has been calm all day. 



Between 4 p.m. and 6 p.m. a thick haze formed which had thinned much by 8 p.m., 

 but has never quite dispersed. From 6 p.m. a few spicules of snow have been falling, 

 but never enough to count. 



The temperature remained low until 4 p.m., but then rose several degrees and has 

 remained steady since. Barometer steady. 



July 19th, 1911. 



4 a.m. A little light cumuliform scud is forming to the N. The glaciers are again obscured 

 by low mist. Calm. Clear. Barometer steady. 

 Temperature fallen several degrees again. 



10 a.m. S.E. wind just commencing, light airs. Overcast. Temperature rising. Barometer 

 steady. Glaciers obscured. 



10 p.m. Temperature remained high until 6 p.m., and then fell quickly to normal. 



S.E. airs and overcast sky, with a little snow, prevailed until the same hour after which 

 the sky cleared except for low cloud over Geikie Land and to the N. Slight haze still. 

 Barometer falling. 



N.B. The whirlwinds of drift seen during the morning of the 18th on the sea ice 

 proved, as I suspected and suggested at the time, to have been of sea smoke from a large 

 pond of open water, probably formed by the pressing up of water from under a depressed 

 portion of sea ice during the high tide, or through a crack formed during the recent fall of 

 temperature. 



July 20th, 1911. 



4 a.m. Calm. Clear, but slightly hazy. Glaciers obscured. Temperature risen a little but 

 now steady. Barometer steady. 



4.30 a.m. Rushing sound of wind and pressure from behind Cape Adare. It is hard to resolve 

 this noise into its elements, but I went out and listened to it without a helmet and could 

 distinguish two components at least ; one a rushing sound like wind among trees, and a 

 faint noise of creaking and grinding. 



10 a.m. Southerly airs. Overcast and hazy but clear to S. Temperature risen 6 F. 

 Barometer steady. 



6 p.m. Rather hazy. The predominant feature of the month's weather so far has been the 

 amount of haze. I have been rather at a loss how to enter this in the weather column, 

 but have finally contented myself by counting the sky as clear when I could see the stars, 

 and noting the haze under remarks or in the cloud column. This haze when it thickens 

 forms the indefinite snow cloud, like a high level fog, I have called Nimbus. As it gets 

 lighter and we get the sun back the division between haze and Nimbus will naturally become 

 more arbitrary, but it should be quite possible to differentiate them.
