set in, and the pressure again rapidly declined to 28*80 inches 

 on the 25th, after which it rose, till on the 28th it reached 

 29-40 inches. 



Including melted snow, the rainfall amounted to 2*83 inches, 

 which is slightly in excess of the amount (2" 51 inches) registered 

 in the previous February. There were 10 dry days. 



In regard to the average temperatures — maximum, 42°, and 

 minimum, 30° — these, compared with 45° and 34° in 1905 and 

 41° and 32° in 1904 respectively, were somewhat low, owing to 

 the amount of frost registered during the month. Frost occurred 

 on 19 days, to the total of 92°, whereas in 1905 the amount 

 for February was only 35° on 11 days. The lowest readings 

 were 22° on the 5th, 20° on the 12th, and 22° on the 24th. 



The cold weather had its natural effect on vegetation. Plants 

 which were on the move were checked, and those early-blooming 

 rhododendrons which were opening their buds in January were 

 severely injured, while all soft shoots on evergreens were 

 blackened. The first open blooms on Daphne Mezereum were 

 observed on the 6th, and the first crocus on the 20th, while the 

 snowdrops were in full bloom all month. 



March. — During the first week the weather was fine and dry. 

 A change set in on the 6th, when a sharp gale, with rain, 

 occurred in the morning. Rain also fell on the 7th, while the 

 8th was wild and stormy, with heavy showers of hail and rain. 

 These conditions prevailed until the forenoon of the 9th. On 

 the 11th, which was also stormy, there was a fall of snow. 

 Thereafter for several days the weather kept dry and frosty, 

 snow again falling on the 14th, while on the 15th and 16th a 

 considerable quantity of rain fell. The latter half of the month 

 was generally bright, dry, and sunny, though, on account of the 

 easterly winds, at times very cold. The closing days were much 

 milder. 



The barometric readings show that the atmospheric pressure 

 was erratic and irregular during the first half of the month. 

 On the 1st the pressure was 29*30 inches, and on the 3rd, 30*10 

 inches. A fairly steady decline to 29*30 inches on the 9th, then, 

 with a rise of four points on the 10th, was followed by the 

 sharpest fall of the month, when, during the storm of the 11th, 

 the reading was 28*90 inches. The subsequent rise was equally
