development of flower and growth of the earlier-growing species 

 was sadly checked by the cold wind and low temperature. The 

 hailstorm on the 2oth had a disastrous effect on many trees 

 and shrubs. In many cases the young shoots were blackened 

 and broken, while such subjects as acers and chestnuts had their 

 leaves torn and lacerated and ruined for the season. The fine 

 promise of a crop of fruit on apples, pears, plums, &c., was 

 dispelled by the same storm, as the trees were literally stripped 

 of their flowers and embryo fruit within an hour. The leafing 

 of the oak occurred on the 13th, and the ash on the 28th; in 

 the former on the same date, and the latter a week later than 

 in the previous year. 



June. — After the 1st, which was showery, there was a marked 

 improvement in the weather, which became dry and warm. 

 These delightful conditions prevailed for some time, and no rain 

 fell until the evening of the Hth, when there was a light drizzle. 

 Heavier rain fell on the I7th, and, though more or less rain 

 fell on most days thereafter, the weather, on the whole, was 

 pleasant and enjoyable — indeed, several days were very warm 

 and bright, notably the 18th and 19th. 



When the fine weather prevailed there was a fairly high and 

 steady line of atmospheric pressure. On the 1st the barometer 

 indicated 29"30 inches, then, after a sharp rise to 30"00 inches 

 on the 3rd, it kept above that point until the 14th, and on 

 several occasions was as high as 30' 20 inches. A slight de- 

 pression occurred on the 15th, but the pressure kept about 

 30'00 inches until the 22nd, when it fell almost steadily to 29-50 

 inches on the 27th, on which day there was a strong S.W. wind; 

 then, after a rapid rise, it kept at 29*90 inches during the two 

 last days of the month. 



The rainfall of Jime has for several years been low, and no 

 exception occurred on this occasion, as only r69 inches were 

 registered. There were 17 dry days. In the previous June the 

 rainfall was only 0'82 inch, and there were 22 dry days. 



In regard to the temperature, although the thermometer in 

 shade was only above 70° on four occasions — 9th, 10th, 11th, and 

 12th — it was above 60° on 26 days, the result being that the 

 average maximum (65°) is 1° higher than in June of 1905,
