There were light winds from the N.E. and N.W., and the rainfall 
was limited in amount to only 0°60 inch, of which 0°40 inch fell 
on the 18th, There were twenty-eight dry days. This month 
was very similar to May, 1895, the chief feature being the very 
limited rainfall. On three days the maximum temperature in the 
shade was over 70°, and only on six days was it below 60°, while 
the minimum was only four times slightly under 40°, Con- 
sequently the average temperature was high for the month, the 
maximum being 63° and the minimum 43°. The fact that no 
frost occurred in May has again to be noted. 
With the bright sunshine and the absence of frost, vegetation, 
already abnormally forward, received no check; and there was a 
wonderful development of leaf and growth during the month. 
The Oak was in leaf on the 3rd and the Ash on the 12th, both 
being slightly earlier than in 1895. Hawthorn, Laburnum, Bird 
Cherry, and Horse Chestnut were in bloom by the 12th, also 
Rhododendron Cunninghami, Hort., and &. ponticwm, Linn. 
The cuckoo was heard on the 11th, or eight days earlier than 
in 1895. 
June.—After the lst, which was a dull though otherwise a fine 
day, the wind changed to the N.E., and for fully a week thereafter 
the weather was dull and showery. ‘Thunderstorms occurred on 
the 4th and 8th, after which the weather was fine and warm. 
Although, after the 15th, westerly winds prevailed and several 
days were showery and ungenial, the readings of the barometer 
showed that the pressure was fairly steady, the lowest point being 
29:30 on the 17th, when heavy rain fell during the early part of 
the day, and the highest points on the 26th and 29th, when 
30 inches were recorded. The rainfall was above the average, 
4-07 being registered—the greatest amount for one day was 0:94 
inch, which fell on the 4th. There were sixteen dry days. The 
highest day temperature in the shade was 78° on the 16th. This 
temperature is the same as that of the hottest day of 1895, viz, 
26th June. The average maximum temperature was 65° and 
the minimum 49°, the former being 1° less and the latter 3° more 
than that of the corresponding month of 1895, 
The rains in the early part of the month, after the warmth of 
May, gave an impetus to vegetation, and the development in 
growth was exceptional; in fact, such quality of foliage on trees
