A year's weather. 397 



Councillor Buck noticed at Perran a remarkable swarm of one 

 of the cockchafers, Rhizotrogus solstitialis, L., which almost covered 

 the outsides of some of the houses. The farmer should see that 

 all cockchafers are destroyed, as the beetle both in the grub and 

 perfect state is harmful to vegetation.

September 20th, 1892. 



SEPTEMBER. 



We have had only about eight Septembers during the 

 last 43 years so dry as the last one. Our average rainfall for the 

 month is three and a half inches, but last month under two inches 

 fell during that period. We had wet on 16 days, which singularly 

 is the average number of days on which rain falls in September 

 here, but half of them only registered one-hundredth of an inch 

 each, or under one-tenth of an inch for the eight days. We had a 

 dribbling rain about the 7th and 8th, a heavy shower on the 20th, 

 rain which fell somewhat heavily on the 27th, a little lighter, but 

 continuous on the 28th, which finished in very heavy rains on the 

 29th, with these exceptions we had practicallj'- a dry month. Mr. 

 Davey gives me the September rainfall in Kennal Vale at 2*88 inches, 

 an inch heavier than at Truro. 



September, 1891, was a sad month to the farmer, but September 

 this year was more favourable as regards rain, as the downpour was 

 less by 1.13 inches. We saw the sun on 28 days. The month 

 suffered from coldness. We did register on one day 70 degress in 

 shade, but registrations of 75, 76, 77, 78, 79, 81, and 82 degrees
