MARCH, 1911 continued. 



March 10//(, 1911 continued. 



The principal types are small irregular granules, balls of snow with six small spikes, 

 six-sided plates of Type Bll 11, rods with or without dumbbell-like protuberances at the 

 end, and plain crystals of hexagonal symmetry, but with more or less of the rays missing. 



About 5 inches of snow is estimated as having fallen, the result being obtained by the 

 comparison of a dozen thicknesses on a level part of the beach. 



The wind swung between 10.30 and 11 a.m. from N. to N.E., blew up to force 2 for a 

 few minutes from that direction and then swung round to the E.S.E., from whence it is 

 still blowing. It is very gusty, varying from none at all to force 4. 



1.30 p.m. At about 12.30 a gust blew for about 5 minutes from the N.E. up to force 4 or 5. The 

 direction changed back to E.S.E. immediately. Between 12 and 1 o'clock the snow changed 

 back to the flaky type with iarge quantities of interlocked crystals of Types Fl 1 9 and Fl 110. 

 The wind was rising and a low drift beginning to fly. 



2 p.m. Wind increasing force 3 to 5. .Slightly less falling snow, but the wind is raising a low- 

 flying drift. 



p.m. Wind fairly steady at force 4 to 5. Snow falling and drift flying. 



Snow principally small-grained with many crystals of type Fll 9. 



An estimation of falling snow now becomes rather difficult because of the drift, but 

 I should think that 3 inches since 2 p.m. would be an under-statement. 



I find a complete garb for observation in this wind and temperature consists of a 

 pair of long thigh sea-boots (leather), an oilskin coat, one of our thickest type of Jaeger 

 woollen caps, and a pair of half mits with fur mits over them. 



To prevent trouble with flying pages of a book, I have got a piece of matchboarding, 

 3 inches by 4|- inches, and have pinned a sheet of paper on that with 4 drawing pins. It 

 answers very well, though if we had one to spare a sketch block would do as well. 



The barometer which had been falling all day, has reached its limit at 28'918 and is 

 now rising. 



8 p.m. Wind increased and still very gusty, force 5 to 8. Heavy drift. 



Some snow falling, but impossible to tell percentage of true snow from drift. All fine 

 snow, no flakes. Cape Adare is obscured and it is difficult to see the hut from the meteoro- 

 logical screen. 



D 



9.30 p.m. Wind increased, estimated at force 7 to 8 with gusts up to 9. Steady drift. Already 

 the ridges have been stripped of the snow that has fallen to-day, and drifts are thigh-deep 

 in the hollows. No falling snow. 



March llth, 194k 



8 a.m. Wind blowing force 7 to 9 with heavy drift. Thermograph is drifted up and not 

 acting, and the ink appears to be frozen. 



11 a.m. Wind blowing slightly less strong and fairly steady. The sun has been shining faintly 



through the clouds for the last 2 hours. 



Strong drift flying but I think no falling snow. The Stevenson Screen has collected 

 inside it the only drift that is to be seen within 40 or 50 yards of it. It seems badly 

 constructed for this particular phase of the Antarctic climate, but it is difficult to see how 

 to improve on it. 



12 noon. Wind about the same as at the last observation, but the drift is slightly less because 



there is less snow to drift. Sky becoming much lighter to the N.W., but there is no break 

 yet. A lower strip of Fracto-cumulus has formed from the N.W. to S.W. about 8 to 10 

 above the horizon. The sun is shining continuously through the snow-cloud haze. I 

 have logged these clouds as Nimbus because they are snow clouds, but they are not at all 

 like the definition of Nimbus, being merely a dull haze of cloud without any break. I 

 changed the Sunshine Recorder card at noon, but there is no mark on it. 



2 p.m. Situation unchanged. Wind gusty and slightly less.
