MARCH, 1911 continued. 



March 19th, 1911 continued. 



10 a.m. Wind the strongest yet. I took 4 one-minute readings on the anemometer and they 

 were as follows : 5246,06 to 5246,85 (a comparative lull), to 5247,96 (a gust), to 5249,17 

 (the same gust), to 5250,01 (end of gust and beginning of lull). This makes the wind in the 

 gusts up to 72 miles an hour for an interval of 1 minute. The detached Cumulus over 

 the sea to the N.W. is still rising rapidly and dissipating, though at a somewhat greater 

 height than before. The snow-cloud is a little thicker and the upper clouds are blotted 

 out altogether. 



12 noon. At one-minute intervals the readings on the anemometer were as follows : 5367,13 

 to 5368,24, to 5369,27, to 5370,68, up to 84 miles an hour the last reading. Clouds 

 unchanged but heavier. 



2 p.m. The wind has reached hurricane force. The anemometer registered 73 miles an hour 

 for the 2 hours, and when I arrived it was broken and gave no movement of figures at 

 all. I have taken it down and put it into Borchgrevink's hut until there is an opportunity 

 to look at the extent of the damage. It is impossible to walk against the gusts, one has 

 to wait for a lull. The sky is shrouded in the snow-cloud moving from the E.S.E. 



6 p.m. The instruments are too delicately constituted for this weather. 



The minimum dumb-bell has been shaken down into the bulb and the maximum 

 thermometer is reading consistently below the dry bulb (some mercury in wrong end). 



I am reading the dry bulb, minimum spirit column and terrestrial radiation. The 

 wind is dropping, temperature steady, and barometer rising. 



The barograph has been shaken so much by the vibration of the hut that it shows 

 only as a broad blotch, but I have removed it from its shelf and put it on the table where 

 it is steadier, if exposed to more danger of shock. 



March 20th, 1911. 



10 a.m. Browning reports the wind less at 6 a.m., but it is now gradually increasing. The 

 maximum thermometer has resumed duty but the minimum is still impossible. Cirro- 

 stratus clouds are visible over a great part of the sky. They trend N.E. and S.W. A few 

 condensation clouds are forming at fairly high altitudes to the N. of us, while the glaciers 

 are obscured by high flying drift and above the drift is a certain amount of snow scud 

 moving from the S.E. The sun is shining quite clearly but is not marking the Sunshine 

 Recorder. 



12 noon. Strongly marked Cirrus Radiant with radiant point S.E. 



2 p.m. Two well-marked series of Cirrus and Cirro-stratus. The lower one of Cirrus trends 

 E. and W. and the upper one of Cirrus and Cirro-stratus trends N.N.E. and S.S.W. Heavy 

 snow-clouds to the S. on the mountains. 



Drift flying to the N. and W. but not here. 



6 p.m. The clouds are arranged in cone form with the point of the cone to the N.W. From 

 the point for about 20 is an unbroken mass of stratus gradually becoming thinner and 

 finally being superseded by rays of Cirro-cumulus which at first are crowded together, 

 but gradually become more and more spaced until the ones to the East of the zenith seem 

 to form a Cirro-cumulus radiant with the radiant point to the E. over Cape Adare. The 

 wind has dropped considerably and the temperature is beginning to fall again while the 

 barometer rises steadily. 



6.30 p.m. Browning reports two flashes as of sheet lightning across the Western Mountains. 

 The flashes were of white light and were quite momentary with hardly a second between 

 them. 



March 21st, 1911. 



8 a.m. Heavy cloud spreading over the sky from the N. Very dense. 



Heavy snow falling over the sea. Spicular snow commenced falling here at 7.30. As 

 yet no definite crystals but all spikes and irregular granules.
