METEOROLOGICAL NOTES DURING THE YEAR 1897. 169 



which there were only thirteen days without rain. On several 

 occasions the rainfall was heavy; on the 11th no less than IJ 

 inches fell — the total amount resristered for the month beinsj 5*51 

 inches, much above what fell in August, 1896, though J inch less 

 than in the same month of 1895. 



The atmospheric pressure was somewhat low. Only on one 

 occasion was it above 30 inches ; this occurring on the 3rd, when 

 it was at 30*10. There was a quick fall to 29*50 on the 6th, and 

 the pressure then ranged between 29*70 and 29*10 all month. 

 The winds varied a good deal in direction and force. 



Despite the heavy rainfall, the temperature was high, and as 

 the maximum thermometer in shade was ten times above 70° and 

 only once below 60", the averages are higher by 4° in each case 

 than in August, 1896, the figures being — maximum, 67°; 

 minimum, 52°. 



The moist, warm weather tended to keep vegetation fresh and 

 bright. Such trees as the Lime and Sycamore, which usually 

 begin to lose their foliage in our city parks by the third week of 

 August, were quite fresh at the end of the month. Grain crops 

 filled up well, but were not ready for harvesting during the month. 



September. — The weather was showery and somewhat colder 

 until the 6th, then it kept dry and fine until the 20th, excepting 

 on the 16th, when we had a heavy fall of rain. Showery, and at 

 times disagreeable weather prevailed more or less until the end 

 of the month. There were sixteen dry days, and the rainfall 

 amounted to 3*39 inches. 



The readings of the barometer show a wide range in the pressure. 

 From 29-30 on the 2nd, it rose to 30*33 on the Uth, then it fell 

 rapidly to 29*30 on the 18th, afterwards varying irregularly to 

 29*10 on the 26th and up to 29*90 on the 27th. 



Though no frost was registered, the freezing point was closely 

 approached on several occasions, and the temperature kept a some- 

 what low range, consequently the averages — maximum, 58°; mini- 

 mum, 44° — are even lower than they were in the same month in 

 1896, which in turn were several degrees below those of the 

 corresponding month of its predecessor. 



The low temperature had the natural efiect on vegetation of 

 causinsr deciduous trees to lose their folias^e rapidlv towards the
