MARCH, 1911 continued. 

 March nth, 1911 continued. 



2 p.m. AVind risen to force 9 in gusts, heavy drift flying. Sun showing continuously. Heavy 

 Cumulus banking up to the X.W., giving off Cirro-cumulus at its southern end, which is 

 being blown back from the N.AV. Alto-stratus near the northern horizon trending E. 

 and W. 



4 p.m. AVind dropping a little. A'ery little drift. A radiant of Cirrus with the radiant point 

 N.W. Cumulus banked up under the radiant point and Alto-stratus to N., running E. 

 and AV. AVestern mountains clear and free from drift and cloud. 



6 p.m. AVind dropped. Barometer rising rapidly since 2 p.m. Two series of clouds, the 

 upper of Cirrus and Cirro-cumulus trending N.E. and S.AV. and moving from the N. The 

 lower trending S.E. and N.AV. and moving from the S.W. is of Stratus. Heavy Stratus 

 low down to the N. and over the mountains to the S.W. 



8 p.m. Sky clouding over again with snow scud from the N. AVind about the same as the 



last observation. Barometer and temperature rising. 



Something has gone wrong with the maximum thermometer to-day and it has been 

 reading below the minimum, but I reversed it once or twice and it seems all right now. 



9 p.m. Aurora behind the cloud to the N.E. 



March 18th, 1911. 



6 a.m. The snow-cloud haze over the sky has partially cleared since the observations. Slight 

 spicular snow falling. No wind. Barometer risen considerably. Thermometer falling. 



8 a.m. Snow haze still thick to the S., but broken up into Cumulus clouds near to the zenith. 

 No snow. | inch of snow altogether. Thermometer rising. 



All times in meteorology are Local Mean time as determined by Campbell as 1 have 

 no instructions as to what time to use, and it would be decidedly inconvenient to have a 

 different time for meteorology. 



10 p.m. This afternoon the sky cleared completely and now there are still no clouds. Still 



calm. Temperature falling and barometer rising still (29-304). 



An arch of Aurora to N. and N.E., altitude about 10 to 15 at centre. The arch was 

 never complete but consisted of 3 or 4 detached curtains, and their light was much impaired 

 by the brilliancy of the moon. There is a bright light in the direction of the Magnetic 

 Pole, which Campbell thinks is a glow from an Aurora further S., and I am inclined to agree 

 with him, though up to now I have been inclined to consider this an afterglow from the 

 sunset. It has been seen in the same position now for several nights. 



10.15 p.m. A complete arch is now to be seen in the place before mentioned as being occupied 

 by detached curtains, and at its northern end it turns acutely and rises towards the zenith. 

 This latter portion is very faint. 



March 19th, 1911. 



8 a.m. A\ r hen Browning took the observations at 6 a.m., the wind was light from the S.E., 

 and the weather was clear, an upper layer of Cirro-cumulus, Cirro-stratus and Alto-stratus 

 being present only. 



At 8 a.m. the barometer had fallen a tenth, the thermometer had risen 7 and a wind 

 from the E.S.E. of force 5 to 9 was blowing. The usual snow-cloud haze was spreading 

 over the sky, though as yet so thin that there was still a suggestion of the upper clouds 

 to be seen through it. while in places they were quite clear. A heavy roll of Cumulus was 

 low down on the northern hozizon, while a little to the N.N.AV. of us detached Cumulus- 

 formed condensation clouds were rapidly forming, rising and dissipating into an unsaturated 

 atmosphere above.
