seasons in the west- are — (1) Autumn ; (2) winter ; while spring 

 and summer are almost equally wet. On the east winter is 

 considerably the wettest season, and the remainder are much 

 alike, spring and then autumn being a little drier than 

 summer. Taking the months (loc. cit., p. 428), on the east 

 (Christchui-ch) the driest is September, 1-161 in., and the 

 wettest June and July, 3-189 in. and 2-449 in. respectively; 

 and on the west (Bealey) the driest month is Mai'ch, 3-921 in., 

 and the wettest is October, 15'501in., closely followed by 

 December, 14-087 in., a considerable contrast to the same 

 month (1-622 in.) in the east. 



Secondly, as to Temperature. — The average yearly maxi- 

 mum temperature for Christchurch is 88-16° Fahr., the average 

 minimum 25-16° Fahr. ; and for Bealey 78-08° Fahr., and 

 12-38° Fahr. The average temperatures at Beiiley are — 

 Winter, 37-40° Fahr. ; spring, 46-04° Fahr. ; summer, 54-86° 

 Fahr. ; autumn, 48-56° Fahr. ; for the year, 46-76° Fahr. : 

 and at Christchurch thev are— Winter, 43-52° Fahr. ; sprmg, 

 53-24° Fahr. ; summer, 61-52° Fahr. ; autumn, 53-60° Fahr. ; 

 for the year, 52-88° Fahr. The average daily range of tem- 

 perature is of interest ; unfortunately, I can only quote that 

 of Christchurch : — 



Eead in conjunction with the above the following mean 

 monthly temperatures at the same station for the years pre- 

 ceding 1877 are important, though the maximum and mini- 

 mum temperatures for the same period would be more valu- 

 able : — 



The following table show^s the maximum and minimum 

 temperatures at Bealey for a course of years : —
