 April 10th, 1911 continued. 



4 p.m. Anemometer readings : 876(5,79 ; 8767,75 : 8768,77 ; 8769,59. Northern half of the 

 sky is clouding over. Cirrus and Cirro-cumulus from the N.E. to N.W. Barometer falling 

 steeply. Temperature falling slightly. 



6 p.m. Wind has reached hurricane force in gusts. Anemometer readings : 8880,13 ; 

 8880,86; 8882,13; 8883,04; 8884,12; 8885,06"; 8886,41; 8887,56. 

 Barometer falling. Temperature steady. 



April Uth, 1911. 



2 p.m. The wind reached its strongest at 12 p.m. last night, and from then gradually decreased. 

 At the 6 a.m. observations it was from force 6 to 8, and at the 8 a.m. observations from 

 force 5 to 6. Unfortunately, the anemometer was torn from its place last night, and 

 accurate readings are not possible until it is refitted. The wind has swung gradually 

 round until it is now S. 20 W., and blowing force 3 to 4. 



Sky clear all day and full sun. The barometer dropped during the night and this 

 morning stood at 28 '54, but it is now slowly rising. 



Temperature high this morning, but again slowly falling. 



6 p.m. Sky clouded over from the N.E. and S.W. A bar of Strato-cumulus has thus formed 

 across the zenith down to 20 above each horizon. 

 Mountains hidden above 4,000 feet. 

 Slight S.W. airs. Barometer rising. Temperature falling. 



April 12th, 1911. 



6 a.m. Sky covered with dense snow-cloud. Barometer rising. 

 Thermometer steady. Wind of force 1. 



8 p.m. Sky cleared this morning and remained clear all day, except for Strato-cumulus on the 

 horizon to the N. 



Barometer rising and temperature falling. 



All minimum observations to-day are unreliable, for both had bubbles in them after 

 the gale. The Terrestrial Radiation thermometer is so bad that I have had to retire it 

 from action (M.O. 3457), and have replaced it with M.O. 3445. The Minimum thermometer 

 proper I managed to save. 



April 13th, 1911. 



8 a.m. Sky clouded with dense snow-cloud. Granular snow falling, j inch of snow fell 

 yesterday and about |- inch last night. 



10 a.m. No change. Slight westerly breeze. Barometer high. Temperature steady. 



8 p.m. Barometer highest yet, 29'632. Temperature falling slowly. Westerly airs or calm 

 all day. Sky cleared during the day, but again overclouded with Strato-cumulus to night. 



April 14th, 1911. 



8 a.m. Barometer unusually high 29'764. Thermometer risen a little. 



Wind blowing from N. 70 E., force 3 to 5. Sky covered with dense snow-cloud. Snow- 

 cloud on Cape Adare at 1,000 feet. Mountains obscured above 4,000 feet. Heavy cumulus 

 off the glaciers. 



2 p.m. Wind blew force 2 to 4 from the N.W. from 12.30 to 1 p.m., then swung to S. 45 E., 

 and is now blowing up to force 8. Anemometer readings : 9380,79; 9381,36; 9382,09; 

 9382,76. Barometer falling and temperature rising. 

 Heavy drift. Sky obscured by dense snow-cloud.
