 excellent display. The autumnal coloration in the foliage of 

 many deciduous trees was also more pronounced than usual, 

 whilst the defoliation was not very apparent until towards the 

 end of month. 



October. — The weather of October was on the whole dull, 

 changeable, and showery. During the former part of the month, 

 though the days opened fine and bright, the afternoons were 

 often dull and wet. Towards the 10th the first touch of winter 

 was experienced, and though no frost was registered during the 

 month the thermometer was frequently hovering about freezing-

 the day advanced the fog cleared off and the sun broke through. 

 The closing days of the month were dull and wet, and there was

 days. 



No frost was registered this month at Queen's Park, and the 

 average maximum temperature was 53° and the average mini-
