NOTES AND REMARKS UPON THE WEATHER. 193 



thunderstorms occurred. The third week was cold and dry, with 

 a prevalence of easterly winds. Rain was registered on the 22nd, 

 23rd, and 24th, but, with these exceptions, dry weather prevailed 

 until the last two days, both of which were extremely raw and 

 disagreeable. 



With the exception of the change which occurred from 29*60 

 inches on the 1st to 28" 80 inches on the 2nd, when a gale of 

 some severity was experienced, the range of atmospheric pressure 

 was moderately high, with no outstanding feature of variation. 

 The range was chiefly between 29 "40 and 30' 00 inches, the 

 latter point being only slightly exceeded on the 17th, 18th, and 

 19th, and again on the 28th and 29th, with the pressure rapidly 

 declining on the 30th and 31st, when it was down to 29*50 

 inches. 



Rain fell most frequently in the early part of the month, the 

 total amount registered being 3 '63 inches, which is slightly under 

 what was registered in the previous May. There were 13 diy 

 davs. 



The absence of sunshine and the prevalence of cold winds had 

 their natural effect on the day temperature. The average 

 maximum consequently is low, only 53°, which is 1° lower than 

 that of May, 1906. In the case of the average minimum, which 

 was 43°, it is 1° higher than that of the previous May, while 

 the figures were 4° and 2° respectively lower than those of 

 May, 1905. 



While the rains of the early part of the month had a vivifying 

 effect on vegetation, the gain was counterbalanced by the un- 

 seasonably cold, sunless weather experienced during the latter 

 part, consequently growth was slower and later than usual. The 

 gale on the 2nd sadly mutilated the young 9 soft foliage of Acers 

 and Chestnuts, also destroyed much of the bloom on Rhododen- 

 drons. The display of bloom on most deciduous trees and shrubs 

 was more irregular than usual, some specimens being profuse and 

 others sparsely flowered. Pears, Cherries, and Plums in some 

 places were fine, and in others under the average, though it may 

 be noted that the most profusely bloomed plants do not usually 

 set fruits so well as those more moderately flowered. While the 

 leafing of trees was later than usual, the absence of " May frosts " 

 permitted the development without injury, and the foliage of the 

 later species was fully above the average in size and quantity.
