RAINFALL OF GUERNSEY. 



As regards the distribution of rainfall over the year 

 Table I shows that January and February contributed 23%, 

 October, November and December over 48°/ Q , leaving only 

 29°/ Q for the remaining seven months. 



The distribution of rain over the whole island is shown 

 in Table 2. There are, owing to the somewhat partial dis- 

 tribution of the heaviest falls, differences which throw some 

 of the stations a little out of their former proportionate 

 values. For instance, Hautnez collected only 85°/ o5 Grange 

 85°/ 0 and L'Ancresse 79°/ c of the Brooklyn totals, whereas 

 last year their proportions were 90°/ o , 95°/ Q and 96°/ Q . In 

 the case of L'Ancresse the moving of the gauge from Mr. 

 Hocart's at Les Mielles to Fort Doyle (Mr. E. O. Catford) 

 may possibly account for a part of the loss. In the other 

 cases the gauges have not been moved. 



As regards wet days this year has given as many as 

 the previous wettest and the number, 232, exceeds the average 

 by 51. The stations vary among themselves as much as 

 62 days (181 to 243). 



In Table 7 I have collected the results of the measure- 

 ments in Alderney and Sark (as kindly provided by Mr. 

 Rowswell) and I compare them with the falls on the roof 

 of the Library, where the fall for the year has been 

 2*39 inches less than at St. Martin's Road. 



A month's total (October) is missing from the Alderney 

 returns and the gap has been filled by crediting the island 

 with 7 inches for that month, which seems to be a consistent 

 quantity, but of course this is done merely to be able to use 

 the returns of the other months and must not be taken as 

 correct.
