DROUGHTS IN GUERNSEY 



DURING THE FIFTY YEAE PERIOD, 1843-1893. 

 BY MR, A, COLLENETTE, F.C.S, 



PART I. 



Observations on rainfall have been taken in Guernsey un- 

 interruptedly for fifty years, counting from the commence- 

 ment of the year 1843 to the end of the year 1892. We 

 are, therefore, able to compare the droughts of the whole 

 period of the fifty years with those just over. Dr. Hoskins, 

 F.R.S., kept records from 1843 to 1881, while my own over- 

 lapped his during 1881 and continued to the present day. 

 From these I have drawn the facts mentioned in this paper. 



I shall divide this paper into two parts ; the first part 

 will deal with absolute droughts, that is periods of over four- 

 teen consecutive days during which no rain fell. The second 

 part will deal with partial droughts, that is periods of more 

 than twenty-eight consecutive days during which the aggre- 

 gate rainfall did not exceed an average of one-hundredth of 

 an inch per diem. 



See Table I. 



Table I. gives a graphic view of the whole of the absolute 

 droughts. These are found to be seventy-six in number, and 

 to have occurred in forty-two years, that is, there were only 

 nine } T ears out of fifty during which no absolute drought was 

 recorded. Those years were 1843, 1862, 1866, 1873, 1878, 

 1879, 1881, 1885, 1888 and 1892. It is worthy of remark that 

 these years were not all wet years, nor did they differ from 

 the remainder in any appreciable way.
