APRIL, 1 01 1 continual. 



April 23/Y/, 1911 continued. 



2 p.m. At 11.15 a breeze started blowing in gusts from the S.W., and brought with it snow- 

 scud across from the mountains, banking it up on Cape Adare. 



Immediately under the cloud a fog began to form on the Cape. At 12 o'clock 

 Browning noted the scud moving from the S.E. along Cape Adare, and a quarter of an hour 

 later the sky was clear, except for a roll of Strato-cumulus to the N., which is being fed 

 by frost smoke oft the open water. At present it is calm with smith westerly airs. 

 Temperature and barometer fairly steady. 



8 p.m. Calm. Temperature oscillating. Barometer rising a little. 



Clear. Cumulus off Cape Adare. Strato-cumulus along the Northern horizon. Scud 

 or snow mist on the southern part of Cape Adare. 



April 24th, 1911. 



6 a.m. Barometer risen. Calm or southerly airs. Temperature low. 

 Sky clear except for a strip of cloud on the Northern horizon. 



8 a.m. Fine prismatic sunrise. About 8 a.m. scud formed to leeward of Cape Adare in some 

 quantity and travelled fast from the N.W. It has now almost ceased forming. A little 

 condensation cloud on Cape Adare, Mt. Minto and the Glaciers. Strato-cumulus on the 

 horizon. 



Temperature and barometer steady. 



10 a.m. On these bright days the shadow of Cape Adare shows in the morning as a broad 

 blue-black band underneath the purple of the prismatic sunrise colours on the western 

 horizon, and as the sun rises this band sinks until it impinges on the bay and loses its 

 definition. About this time, however, the shadow becomes well marked as a triangle of 

 darker sky to the S.E. and S. bounded by a well-defined straight line. This triangle 

 gradually decreases in size till it finally disappears. 



12 noon. Barometer rising. Temperature oscillating. The barograph had run down on 

 Sunday afternoon. I suppose that I had not fully wound it up the previous Monday. The 

 thermograph is showing a fall of only 4 for 16 F. It has worked rather better for the last 

 two days showing one or two small variations. 



If it does not improve during the week I shall be inclined to try it in here for a week 

 and experiment with it. It is impossible to keep it in the screen owing to the drift. It 

 is at present in a venesta box and has been exposed quite freely to the air during the 

 whole of last week. 



Alto-stratus trending N.W. and S.E. above the northern horizon. The Strato- 

 cumulus on the northern horizon is being constantly fed by the sea-smoke. 



2 p.m. After a good deal of trouble I have managed to re-set the anemometer and start it 

 going again. How long it will last I don't know. Glazed frost very thick on the Sunshine 

 Recorder. 



4 p.m. About 3.30 the sun disappeared behind the Strato-cumulus along the horizon to the 

 N.W. A breeze of force 3 to 4 sprang up from the N.E. and immediately Stratus-clouds 

 formed along the mountains S. of Sabine. 



Geikie Land was obscured and the Glaciers filled with mist, while scud was formed 

 on Cape Adare and carried S. and banked up against the clouds there. Besides these 

 clouds a quantity of scud was brought from the N.E. by the wind. This latter was 

 probably the frost smoke being blown inland. 



The temperature has risen 6 Barometer steady. 



p.m. Temperature fallen 5. Barometer fallen. Ice crystals separating out on every- 

 thing outside. Heavy glazed frost on all glass instruments and ice is separating out of 

 the air as rods, spicules. and grains. 



A band of Stratus and Strato-cumulus to the N. Scud on Cape Adare. Calm. 



8 p.m. Calm and bright. Temperature steady and barometer rising.
