were experienced during the second and tliird weeks, while 

 showers of hail and snow were too frequent. A very unseason- 

 able fall of snow, fully 2 inches in depth, occurred between the 

 14th and 15th. During the latter half of the month many 

 days were bright and clear, but cold, owing to the predominance 

 of easterly winds. The last day, however, was mild, when a 

 thunderstonn, with lightning and heavy rain, was experienced. 



After the fu'st ten days, when the barometric readings were 

 somewhat enatic, the pressure got steadier, with an upward 

 tendency, until the I7th, when it reached 30" 25 inches. From 

 that point it gradually fell to 29*30 inches on the 27th, and 

 continued steady thereat for a few days. 



Though frost was only registei-ed on 10 occasions, the ther- 

 mometer was at or below freezing point (32'') on thirteen morn- 

 ings. The total amount of frost was 62°, the lowest reading was 

 22°, or 10° of frost, on the morning of the 15th. Consequent on 

 the amount of frost and prevalence of cold, easterly winds, the 

 average temperatures are lower than usual, the maximum being 

 48° and the minimum 34°, as compared with 53° and 41° 

 respectively in April, 1902. 



The rainfall (r42 inches) was low for this month, and proved 

 to be the lowest of any month of the year. There were 19 

 dry days. 



Vegetation, which had been naturally advanced by the open 

 weather of the preceding month, got a severe check by the 

 frosts and cold winds which prevailed during the latter half 

 of the month. Most shrubs, trees, and herbaceous plants, which 

 were in a forward state of growth, were severely crippled. In 

 many places the crop for the season on bush fruits. Plums 

 Cherries, Pears, &c., was completely ruined, while the loss in 

 plant nurseries of seedlings and young stock was incalculable. 

 The display of bulbous plants in beds and borders was com- 

 pletely spoiled, even the hardy Narcissi having a crippled 

 appearance. 



May. — Excepting a few diy days in the second week, the 

 weather during the first half of the month was generally dull 

 and showery. The latter half of the month was drier and more 

 pleasant, with some warm days.
