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 R. 2>onticum, Linn. 

 The cuckoo was heard on the 11th, or eight days earlier than 

 in 1895. 



June. — After the 1st, 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, w^esterly 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 beincr reojistered — the 2:reate3t amount for one dav 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
