and average minimum 37°, compared with 6° of frost for one day 

 and average maximum and minimum temperatures 55° and 41° 

 for the preceding April. 



Consequent on the cold, ungenial weather, the hyacinths and 

 tulips which bloomed this month only lasted a short time, and 

 vegetation generally made little progress, being at least three 

 weeks later than the previous year. The trees noted in leaf in 

 the parks were hawthorn, on the 15tb, and birch, on the 20th. 



May. — The milder weather experienced in the closing days of 

 April did not last long, as the 1st of May came in cold, and, 

 instead of the dews expected in the morning, there was a fall of 

 snow and sleet, followed by a cold rain. On the 3rd, however, 

 with a rising barometer, the weather became dry and brighter, 

 though still cold, with the wind from the east and north-east. 

 Frost to the extent of 4° and 3° was registered on the 4th and 

 5th respectively. On the wind changing to the south-west, a 

 thunder storm was experienced on the 15th, accompanied with a 

 strong wind and heavy rain. Dull and showery weather con- 

 tinued till the last week of the month, when it became much

 held on the last Saturday, was a day of bright sunshine, which 

 added greatly to the success of the undertaking. 



The rainfall for the month was heavy (4-45 inches), though 

 there were IS dry days, two days having over one inch each, viz., 

 1-50 inches on the 19th, and 1-05 inches on the 20th. 



Frost occurred on two days to the amount of 7°, and the highest 

 tempei'atures recorded were on the last two days of the month, 

 when 67° were registered. 



The progress of vegetation was much impeded by the cold, 

 searching east winds, the first grass being cut in the parks on the 

 24th, as compared with the first cut on 25th April, 189S. 



June. — The first three weeks of June were like the last week of 

 May — warm and sunny days and cold nights, with scarcely any 

 rain. The only rain registered during this period was 0-05 inches 

 and 0-09 inches on the 4th and 19th. With the last ten days of 

 the month came refreshing showers of rain, and the atmosphere 

 was more temperate. On thirteen occasions during the month the
