MARCH, 1911 continued. 

 March 15th, 1911 continued. 



10 a.m. Cloud haze thicker and fairly heavy snow falling in flakes. FIT 9 and FIT 10 crystals 

 are common, but the majority are small stars with a granular centre. Several of these 

 latter are interlocked to make a flake. Cape Adare is indistinct and the glaciers are 

 blotted out. 



10.10a.m. The snow has been for 5 minutes consisting entirely of large flakes of crystals 

 of types allied to FII 9 and FIT 10. It is now intermediate, part as above and part as 

 at 10 o'clock. 



12 noon. The clouds are breaking up into definite billow-like forms, and are forming roughly 

 a very heavy radiant with a radiant point of unbroken clouds to the W. A few crystals 

 of snow falling (FII 9). 



8p.m. No change. Calm all day. Heavy snow to the N.W. about 4 p.m., but has since 

 cleared. 



March 16th, 1911. 



6.30 a.m. Heavy snow composed of large flakes of immature crystals. Half an inch has 

 already fallen. Slight draught from the N.W. 



12 noon. Heavy snow falling all the morning, about 2 inches up to the present. 



Snow falling in flakes of different sizes, but all composed of rods and immature stars. 

 No different types recognisable. 



8 p.m. This afternoon about 5 p.m. we noticed drift flying off Cape Adare. The glaciers had 

 been obscured all day, and this was the first intimation of a southerly wind approaching. 



A quarter of an hour later the wind struck us, and blew in gusts up to force 4 for a 

 few minutes, with long intervals of calm. About 6 o'clock the wind ceased again and 

 now there is a back-draught from the N. 



The clouds broke up this evening. We saw two radiants, one of Cirro-cumuliform 

 scud with the radiant point to the N.W., and the other of heavy Nimbus with the radiant 

 point to the N. These were present at the same time, but the Nimbus was on the lower level. 

 Over the mountains to the N.W. and W. were two layers of Stratus, one about 2,000 feet 

 above sea-level, and the other about 9,000 feet. 



The glaciers are clear now. Luminous glow of Aurora was observed at 10 p.m. 



March 17 'th, 1911. 



8 a.m. At 7 this morning the sky was almost clear with the exception of low Cumulus and 

 Stratus to N., which were probably caused by rising sea-smoke. About 7.15 a.m. Warning 

 and Sir George Newnes glaciers became obscured by heavy snow-cloud which gradually 

 moved from the S.E. until now it covers about a third of the sky. It advanced at first 

 with broad Cumulus rays thrown out ahead of it, but the easternmost rays moved faster 

 eastward than the others, and gradually they all merged into one dense cloud. The moun- 

 tains are now obscured and heavy snow is falling from the edge of the cloud. 



A fine mock sun of the halo of 22 was visible at 7.30 this morning with the red, 

 yellow and green well marked, but the blue indistinct. 



After the sun was overclouded by light Cirro-cumuliform snow-cloud a very fine 

 effect was produced by the rays of white light striking across the shadow-darkened blue. 



10 a.m. One heavy snow-cloud has passed over and now is breaking up to the N., while another 

 is showing over the southern horizon and obscuring the glaciers. A few snow grains are 

 falling. When I took observations the wind blew about force 1 from the S.20W. and 

 then immediately swung to E.S.E. and blew up to force 4, when a low drift was flying. 

 Before the southerly wind reached here the drift was flying northward from the N. point 

 of the beach. A break in the snow-clouds shows an upper layer of Stratus trending E. 

 and W.
