With regard to the temperature, there are some interesting 

 points of comparison with that of the preceding year. Six 

 months of the year — viz., February, March, May, July, August, 

 and October — had a higher average temperature than in 1900, 

 while the average maximum temperature for July, 1901 (69°) 

 is greater by 2° than the average maximum of any month of 

 1900, and has only been equalled once during the last eight 

 years — namely, in June of 1899. Frost was registered on 70 

 occasions to the extent of 327°, although the thermometer was 

 at or below freezing-pomt (32° Fahr.) 78 times. In 1900 the 

 amount of frost recorded was 326° for 57 days, and the freezing- 

 point was touched in all 64 times. The lowest reading of the 

 thermometer in 1901 was 17° (15° of frost), on 16th November, 

 while the lowest reading of 1900 was 9° (23° of frost), on 11th 

 February. There were only two occasions on which the ther- 

 mometer did not rise above freezing-point during 24 hours. In 

 the previous year this happened on five occasions. 



The coldest month of the year was February, when the frost 

 totalled 97° for 20 days. July was the warmest month, with 

 a mean temperature of 62°; in 1900 July was likewise the 

 warmest month, but the mean temperature was 60°. The 

 highest reading of the thermometer in the shade was 77°, occur- 

 ring on two occasions, both in July — the 5th and 19th. In 

 1900 the warmest day was on the 15th August, when the ther- 

 mometer rose to 75°. 



The maximum thermometer was at or above 70° on 2 days in 

 May, 2 days in Jime, 16 days in July, and 4 days in August — 24 

 times in all — whereas in 1900 this point was touched 21 times, 

 and occurred in June, July, and August. 



During the year there was an unusual prevalence of easterly 

 winds, as shown by the following records : — From the south-west, 

 218; west, 43; north-east, 4; east, 65; north-west, 6; south, 1; 

 and south-east, 28 days, respectively. Thus, excluding the direct 

 north and south, the western group shows 267 and the eastern 

 group 97 times, against 290 for the western and 72 for the 

 eastern in 1900. 



From the barometric records it is seen that the range is higher 

 than in the previous year. The highest reading of the year, 

 30'40 inches, was taken on the 25th, and again on the 26th,
