was succeeded by several dull cold days with heavy showers. On 

 the 16th, with the wind northerly, the first sharp frost of the 

 season occurred. 



For several days the frosts continued, accompanied by fogs in 

 the city in the mornings. The dry weather continued until the 

 26 th, after which it was more or less rainy till end of month. 



The changeable character of the weather is well shown by the 

 wide and erratic range of the barometric readings. On the 1st 

 the atmospheric pressure was at 29 -65 inches and 29-70 inches on 

 the 3rd. A sudden drop to 28*90 inches occurred on the 4th, 

 which was succeeded by as quick a recovery to 29*90 inches on 

 the 5th. There was a gradual rise, and 30*30 inches was 

 recorded on the 10th and 11th. From that point there was 

 a sharp decline, and 29*30 inches was indicated on the 15th. 

 The following day the pressure was up five points, and kept 

 within a range of half an inch until the 29th when, from 

 29*80 inches, it suddenly fell to 28*90 inches, and kept at that 

 point on the 30th and 31st. 



"With eighteen dry days in the month, there was a rainfall of 

 2*57 inches. On four days the amount was over a quarter of an 

 inch; the greatest for tw r enty-four hours was 0*71 inch, regis- 

 tered on the morning of the 4th. In October, 1904, the rainfall 

 was 2*12 inches, with eleven dry days. 



Frost, amounting to 57°, was noted in the mornings. This, 

 with the cold winds, tended to keep the temperature down — hence 

 the averages are low, the maximum being 50° and the minimum 

 36°, compared with 54° and 43° respectively for October, 1904. 



The frosts finished the season so far as tender plants were 

 concerned. The most notable damage in our parks and gardens 

 was the ruin of the early outdoor chrysanthemums, which, 

 despite the good summer, were later in flowering than usual, and 

 were just coming to their best when caught by the frost, w'hich 

 utterly spoiled what promised to be a grand display. The frost 

 also completed the defoliation of deciduous trees. 



November. — The changeable, rainy weather which prevailed 

 during the last week of October continued until the middle of 

 month, only three days in that time being without rain. A week 

 of dry frosty weather followed, and dense fogs hung over the city 

 during the prevalence of the frost. A change set in on the 21st,
