For the week preceding the 19th, the Diaxiiiumi and 

 minimum temperatures varied only a few degrees, the 

 maximum keeping between 70° and 80°. On the 20th when 

 the hot Avind l^egan the temperature went up to '^^^ , and it 

 rose still higher, to 92° and 95° F., on the two following days. 

 Then the hot north wind ceased and it was succeeded by a 

 south-easterly breeze bringing clouds. Rain fell on the 25th, 

 26th and 27th, and it ended in a fall of snow, which covered 

 the hills surrounding Pietermaritzburg and lay there for a 

 couple of days. Although the temperature always falls, it is 

 quite exceptional to have a fall of snoAv. On the 29th the 

 conditions had returned to what they were up to the 19tli. 

 During the time of the disturbance, and for a few days before, 

 the barometer showed constant variations, rising and falling 

 about an inch. 



I will give another good example of this kind of disturb- 

 ance. The maximum shade temperatures for Pietermaritzburg 

 were : on September 25th 80°, on the 26th 86°, on the 27th 

 1 00°, on the 28th 76°, on the 29th 69°, on the 30th 64°, on 

 October 1st 75°. Rain began on September 29th and continued 

 until October 2nd. At Pietermaritzburg 5'99 in. were 

 recorded, but this was veiy much below the average for 

 Natal. Durban had 15'66 in., at the Cornubia Estate
