point (32°). The average maximum and minimum temperatures 

 were 38° and 26° respectively. In 1899 these figures were 43° 

 and 32° respectivelj\ 



The rainfall of the month was 2-68 inches, and included a 

 quantity of melted snow. There were 20 dry days. 



The sharp frosts experienced during the month checked 

 precocious vegetation, and had a most damaging effect upon those 

 shrubs which made late growth, or whose tissues were surcharged 

 with sap, consequent on the mild wet weather which prevailed 

 during the greater part of the four preceding months. Such 

 plants as Aucuba ja2)onica, certain forms of Rhododendron 

 ponticum, and the common laurel suffered severe injury in the 

 young shoots. The foliage of the laurel especially, was browned 

 to a gi'eater degree than usual in the western and northern 

 parks. In the case of Olearia Haasti, which, by the way, we 

 find to be an excellent town plant, in several parks it was hardly 

 injured, whilst in others it was killed to the ground. 



March. — As in the previous month, the weather in March 

 continued cold and frosty, with a period of fine clear days. 



The opening days were bright and springlike, but on the 19th 

 the atmosphere became colder, and snow fell to a depth of 2 

 inches. Thereafter the weather remained cold and dull, with a 

 recurrence of snow on the 27th and 28th. 



The atmospheric pressure was regular for the first fortnight, 

 but on the 14th the barometer fell sharply from 30-38 inches to 

 29 '10 inches on the 19th, the day on which the snowfall occurred. 

 From this point it gradually rose until it reached 30'05 inches 

 on the 31st. 



The rainfall recorded this month was very moderate — the 

 amount measured (0'28 inch) being little more than a quarter 

 of an inch. There were 27 dry days during the month. 



Frost to the extent of 83° was recorded for twenty days, and the 

 lowest thermometer was 22° (10° of frost) on the 18th. For the 

 same month of 1899 there were 72° of frost for nine days. The 

 average maximum temperature for the month was 44° and the 

 average minimum 31°, against 46° and 35° respectively for the 

 corresponding month of last year. 



Vegetation was held in check by the cold and frosty winds
