JUNE, 191 1 continued. 



June loth, I nil. 

 2 a.m. Calm or southerly airs. Clear, no clouds. Barometer and thermometer steady. 



10 a.m. C^alm or southerly airs. Clear, no clouds. Barometer and thermometer steady. 

 Thermometer has risen 4 or 5 degrees since 8 a.m., when the reading was low 25 F. to 

 -20 F. 



2 p.m. Between 1 p.m. and 2 p.m. a broad band of Strato-cumulus fringed with Cirro-cumuli- 

 form scud formed from behind Cape Adare to the E. and spread over the sky in a N.N.W. 

 direction. The temperature is falling. All the morning there has been a thin layer of 

 tree-like cloud on the northern horizon which is probably the result of convection currents 

 over an open lead of sea-water. 



8 p.m. Calm and clear. The clouds gradually thinned after 4 p.m. until now there is only a 

 thin band of Stratus on the horizon. Temperature falling slightly. Barometer steady. 



June 16th, 1911. 



4 a.m. Calm and clear. Stratus and scud are forming to the S. of us and on Cape Adare, 

 and the glaciers are obscured. Barometer falling slowly. Temperature steady. 



10 a.m. Calm clear. Strato-cumulus and scud to N. and S. Barometer and thermometer 

 steady. 



12 noon. Calm. Clear. Stratus stretches outward across Geikie Land from Warning Glacier 

 at a height of a few thousand feet, and a long line of similar cloud stretches along in 

 front of the mountains from S. to N.W. 



It seems probable that this is due to convection currents above a freshly-opened crack. 

 Similar clouds to the N. Dry bulb thermometer 31-8 F. ; the first time it has passed 

 -30F. 



2 p.m. Calm. Clear. Clouds have dispersed from the W. and S. and the cloud off Warning 

 Glacier is much smaller. Heavy Stratus toN. from horizon to 15 altitude. Above this is 

 a broad band of Cirro-cumuliform. Stratus reaching from N. 20 E. to N.W T . at an altitude 



of 30. 



Temperature has risen again. 



4 p.m. Calm or southerly airs. Cloudy. Dense snow-cloud capping Cape Adare and spreading 

 northward to increase the bank of Stratus running from N. to N.W. The glazed frost 

 has almost disappeared from the thermometers inside the screen. (The frost had lightly 

 covered the instruments between 10a.m. and 12 noon.) No clouds to S. and W. 



6 p.m. Mushroom-shaped cloud spreading from Cape Adare. Stratus to N. dispersing. 

 Glaciers clear. Calm. Cloud}'. 



8 p.m. Calm. Overcast. Barometer steady. Temperature risen 7. 



Cloud spread over the sky from Cape Adare until the only blue sky is a narrow strip 

 from S. to N.W. near the horizon. Warning glacier is obscured, but only by clouds. A 

 westerly wind of force 3 to 4 blew for a few minutes about a quarter to 7. The glazed 

 frost has been entirely absorbed into the atmosphere from the instruments in the screen. 

 A sharp southerly wind was reported from the end of Cape Adare this morning by Campbell. 



10 p.m. Calm or northerly airs. Temperature still rising. Barometer steady. 

 Clouds thinning to W. and N. but still thick over Cape Adare. 



June 11 f h, 1911. 



4 a.m. Overcast at 2 a.m. but clearing now from N. and zenith. Thick clouds on Cape Adare 

 and glaciers obscured. Calm to S. wind of force 1 to 2. 



Temperature fell 11 to 2 a.m. but has risen 5 since then. Barometer steady. Close 

 halo round moon showing through the scud. 

 Inner ring white, to brown, to green.
