Rhododendron Eugenie, which was in full bloom by the 20th, 
making a pleasing display amid the shrubbery, while the bulbous 
plants in the plots in the parks and squares bloomed brilliantly, 
notably hyacinths and Narcissi. The earlier tulips, on the other 
hand, were not so good, owing to the hard drying winds of the 
preceding month having injured the expanding buds. 
May.—The bright pleasant weather of the close of April did 
not hold through this month, The weather was backward, with 
hard cold north and north-east winds, and a tendency to frost at 
nights. Until the 12th the weather was dull and changeable, with 
frost and showers of hail on the 15th, after which hard dry 
weather was experienced till the close of the month.. Frost was 
registered on four days, and amounted to 6°. The highest 
thermometer reading was 65°, and the lowest 30°. The average 
maximum temperature was 58°, and the minimum 40°, almost 
identical with that of May, 1897. The range of the barometer 
readings was wide, and varied from 30°10 on the 7th to 28-70 on 
the 11th, rising rapidly and steadily to 30:10 onthe 19th. Until 
the end of the month it had a steadier but lower range. Rain 
fell on nine days to the amount of 2:04 inches, which is slightly 
under the amount recorded for the same month in 1897. 
Vegetation, which was in a forward state in April, lost 
considerably, and was somewhat damaged by the cold winds 
and low temperature of this month. The tender leaves of the 
trees, particularly the Horse Chestnut, suffered severely by the 
sharp frosts and showers of hail which occurred between the 12th 
and 18th, and the fruit crops were likewise severely damaged. 
Several species of trees and shrubs bloomed remarkably well 
through this month, notably Cherries, Pyruses, and Lilacs; and 
the late-flowering tulips were very fine, compensating for the weak 
display made by the earlier varieties. The Oak leafed on the 6th, 
and the Ash on the 18th, the former 13 days and the latter 6 
days earlier than in 1897. 
June.—For the first fortnight there was a continuation of the 
cold unseasonable weather which characterised May, with easterly 
winds, and not until the 18th, when the wind changed to the 
south-west, did the weather become seasonably warm. With a 
low barometer (29°20) on the Ist, cold showers of rain fell, after 
which the barometer rose gradually, and the weather became
