MAECH, 1911 continued. 

 March 2nd, 1911. 



10.30 a.m. Campbell has examined the barometers and has found the Fuess Barometer broken, 

 but the Kew Pattern Station Barometer is apparently all right. I gave the Thermograph 

 a vertical mark at 10.30 this morning. 



A wind about force 5 or 6, rather gusty and carrying a little drift was blowing when 

 we turned out this morning. About | inch of snow has fallen (estimated), but at present 

 the sky is clearing and the sun showing occasionally. 



I have started this morning taking accurate readings of the Anemometer with the 

 aid of a watch, and am entering the times in one of the spare columns at the end of the 

 page of the log-book. The other column I am using for recording the occurrence of drift 

 snow. 



10 p.m. Since my last note, the wind has continued with varying intensity but always very 

 gusty. It has never, I should say, reached a speed of above 30 miles an hour, but I have 

 not worked out the Anemometer readings. 



Until 2 o'clock this afternoon the Cumulus clouds were working gradually towards 

 the S., but between then and 8 p.m. there was rather a rapid return towards the X.W. 

 At the 10 o'clock observation the clouds were much denser, a slight snow had commenced 

 to fall, and movement of the cloud was imperceptible. 



March 3rd, 1911. 



8 p.m. Wind to-day has been much less gusty, and towards the middle of the day rose to 



force 7. I find I have been under-estimating the wind force up to now and am therefore 

 slightly changing my scale to bring the Beaufort scale estimations in line with the Anemometer 

 readings up to now. From now on, I shall continue estimation without comparing. 

 About 6 p.m. a well-marked Alto-stratus radiant became visible owing to the dispersion 

 of the lower Cumulus and Ximbus. The radiant point was a little E.S.E. 



10 p.m. Wind almost ceased (2 to 0). Heavy cloud masses, especially dense Ximbus on the 

 Northern horizon. Temperature has been remarkably constant all day. (+24 F. to 



+28 F.). 



March UJi, 1911. 



9 a.m. Sky quite clear but for a few Cumulus clouds in the mountains. Calm witLrsoutherly 



airs. 



6 p.m. At about 5.30 I noticed Ximbus clouds moving rapidly towards the S.W., appearing 

 over Cape Adare. The sky at the time was obscured by dense Cumulo-stratus. 



Stratus and the Ximbus clouds formed a second layer beneath these. At 5 o'clock a 

 wind of from force 2 to 3 blew in 3-minute gusts with about 5- to 10-minute intervals between 

 them. 



At the present time it is calm and has been so for more than 20 minutes. Snow 

 commenced to fall at 5.45 p.m. in flakes of three types : 



(1) Shapeless granules. 



(2) Six-rayed stars of Type E. 10. 



(3) The same stars with little clubs of snow depending from the end of the rays. 



This afternoon we fixed the sunshine recorder, making the necessary adjustments 

 for meridian and latitude, and placed an equinoctial card in the bowl. Owing to our 

 position under Cape Adare, it will be necessary in striking an average of the amount of 

 sunlight, to take into account the loss owing to the shadow of that peninsula. 



8 p.m. The wind dropped completely until 7 o'clock, when a few gusts from the S.E. led us 

 to expect a gale, but at the present observation there is a slight draught from the W. A 

 few crystals of snow are falling, but both to X. and S. of us the snow-fall must be much 

 heavier. 



10 p.m. Wind has gone back to E.S.E. and is blowing in gusts up to force 5, but there are long 



lulls when it is scarcely strong enough to move the Anemometer. The sky is still obscured 

 and our horizon is much reduced by the snow. Xo snow is falling here.
