AUGUST, 1911 continued. 

 August 22nd, 1911. 



8 a.m. Barometer fallen slightly. Temperature falling. Glaciers clear. 



Calm. Clear. A little Strato-cumulus low down on the northern horizon suggests 

 frost-smoke and open water to the N. (R. E. P.) 



2 p.m. Clear. Calm. Temperature and barometer steady. All day Cirro-stratus and 

 Alto-stratus clouds trending W. and E., and apparently drawing towards a focus in the 

 W., have occupied the lower portions of the sky, but there has been no cloud within 45 

 of the zenith. 



Much frost-smoke is rising from the open water to the N., but is being absorbed into the 

 atmosphere at a low level. Between 12 and 1 o'clock a whale-backed cloud formed and 

 dissipated again to the S. of the southern end of Cape Adare at a height of about 4,000 feet. 



From time to time trails of frost-smoke formed to the N.W. of Minto and Adam, and 

 occasionally whirlwinds of snow fog have been observed travelling fairly slowly down 

 Warning Glacier. A light southerly air here has been marked most of the day. I shipped 

 the new Solar Radiation thermometer to-day. Its number is MO 952, and it is shipped 

 in the same position as the one last summer. (R. E. P.) 



8 p.m. Clear but hazy. Calm. The southern nine-tenths of the sky is covered with a thin 

 haze through which the stars shine with scarcely diminished brightness, and which is only 

 rendered plainly visible by the contrast this portion of the sky shows against the lighter- 

 hued sky along the N. and W. horizon and by a comparison of the brightness of the stars 

 in the two sections. This afternoon a S.E. breeze blew for some time and was accompanied 

 by a rise of temperature which still continues. The barometer is rising slowly. 



(R. E. P.) 



10 p.m. A S.E. breeze of moderate strength sprang up but only lasted for a short time. 



(R. E. P.) 



August 23rd, 1911. 



8 a.m. Calm. Clear. A little Stratus to the S. and Alto-stratus to the N. Glaciers clear. 

 Thermometer fallen 21. Barometer steady. (R. E. P.) 



2 p.m. Calm. Cloudy. Sky became partially overcast by spread of Nimbus clouds with 

 outliers of Cirro-cumulus from the S.E. Sabine, Herschell, Adam and Minto hidden, 

 but lower mountains clear. A little Stratus has formed also to the N. at an altitude 

 of a few degrees. Temperature steady. Barometer settling slowly. The air this morning- 

 has been full of minute ice spicules whose presence was only rendered visible when looking 

 towards the sun. A number of fern-like crystals have been deposited on the bulb of the 

 Solar Radiation thermometer, and I was again, as yesterday, obliged to clean the Sunshine 

 Recorder sphere. These ice-crystals may be due to the saturation of the air above the 

 open water to the N.W. brought here by N.W. airs and then cooled below dew point by 

 the recent fall of temperature. (R. E. P.) 



8 p.m. Heavy spicular snow in flakes falling. | inch in all. N.W. breeze of force 1 to 2. 



Mountains, glaciers and Cape Adare obscured. Temperature steady. Barometer rising. 

 Overcast with heavy snow-cloud. (R. E. P.) 



9 p.m. Dickason reports clear sky and light southerly wind. (H. D.) 



9.15p.m. N.W. airs. Clear sky. Bank of clouds to the N. and E. behind Cape 

 Adare is the only sign of the recent squall. (R. E. P.) 



August 2Uh, 1911. 



8 a.m. Southerly airs. Clear. Barometer risen slightly. Glaciers clear. Temperature risen 

 19. Cloud cap on Cape Adare. (R. E. P.)
