frost and the low rainfall contributed to the high average tem- 

 perature, the maximum being 45° and the minimum 34°, 

 compared with 41° and 32° respectively in February, 1904. 



The rainfall (2-51 inches) was again low for the month, and not 

 much over what was registered for February, 1904, when the 

 amount was 2-28 inches. 



With the abnormally open weather, vegetation began to move, 

 and the buds on many deciduous trees and shrubs swelled con- 

 siderably. Rhododendron prmcox and R. nobleanum were open 

 by the middle of the month, but got frosted on the 22nd. Snow- 

 drops were in full bloom during the early weeks, and Daphne 

 mezereum about the 25th. 



March. — The weather during this month was of a very variable 

 character — rain falling nearly every day ; but frequently occurring 

 at night or early morning, the day-time was often bright and 

 fine, especially so for the season of the year. The notable excep- 

 tions were on the 9th, which was a wild wintry day, with heavy 

 showers of snow, which melted as it fell. A sharp, severe gale, 

 with rain, occurred on the 15th. On the 22nd a dense fog over- 

 hung the city until 11 a.m., the afternoon being fine and bright. 



The variableness of the weather is well shown by the erratic 

 barometric readings. On the 1st the pressure indicated was 

 29-15 inches, by the 3rd it was at 30-00 inches, which was the 

 highest point touched during the month. The fall was steady, 

 though erratic, till the 15th, when it was down to 28-20 inches, 

 which proved to be the lowest reading of the year. The rise was 

 rapid and regular for 4 days, as on the 19th it was up to 29-70 

 inches, keeping fairly regular within a few points of that figure 

 until the end of the month. Although there were only 6 dry 

 days, the rainfall was just about the average — the amount 

 registered being 3-16 inches. In March, 1904, the amount was 

 1-43 inches, which, however, was abnormally below the average 

 for this month. 



There was a notable absence of frost, as only 1° was registered, 

 compared with 61° on fifteen occasions in March, 1904. Conse- 

 quently, the average temperatures are high. The maximum 

 being 49° and the minimum 37°, in each case 5° higher than for 

 the corresponding month of the preceding year.
