The leafing of tlie Oak on the 13th and the Ash about the 25th 

 was similar in time to the previous year. Seeds in garden and 

 field generally nuide a good start in growth, but many (if the 

 more tender sorts developed imperfectly, or failed entirely in 

 growth afterwards, on account of the want of genial weather 

 conditions. 



The Cuckoo was heard on the llth, and House-Swallows 

 ol^served on the 16th. 



June. — There was no improvement in the weather conditions 

 with the advent of what is usually one of the most pleasant 

 ntonths of the year. Rarely indeed do we experience such a 

 prolonged spell of cold, cheerless, sunless weather in June. Heavy 

 showers of rain, and occasionally hail, fell on most days of the 

 month, while local thunderstorms were somewhat frequent. On 

 the 29th, which was a remarkably pleasant day, during the 

 prevalence of one of these storms, there were part® of the city 

 deluged for a short time at different periods of the day, whilst 

 in some parts not a drop of rain fell. 



The barometric readings do not .show either a w^ide range or 

 any notable change in the atmospheric pressure. On the 1st it 

 was at 29'60 inches, varying only a few points up and down 

 till the r7th, when it touched 29"90 inches, falling about four 

 points the following day, and keeping very steady thereafter till 

 the 24th, when it fell to 29"30 inches, rising slowly aftei-wards 

 to 29-90 inches on the 30th. 



The character of the weather may be gauged by the fact that 

 only on 6 days was no rain recorded. The total amount of 

 rainfall registered was 3"99 inches. In June, 1906, there were 

 only 1'69 inches of rain and 17 dry days. 



With an abnormal rainfall and absence of sunshine the 

 temperature was low, the average maximum being 57°, and the 

 average minimum 47°, compared with 65° and 50° respectively 

 for the corresponding month in 1906. In that year the maximum 

 thennometer in shade was above 70° on four occasions, and above 

 60° on twenty-six, whereas in the year under review it was only 

 six times above 60°, the highest reading being 63° on the 11th. 



Consequent on the somewhat abnonnal conditions, vegetation 

 made but slow progress. Hawthorns were but bursting into 

 bloom during the second week, and flowered very irregularly.'
