The year 1902 has been a dry one. The total is 33*98 

 inches against an average (60 years) of 36*52. Three months 

 proved wet, viz., April, June and August. Owing to the 

 incideDce of these months the year divides itself into three 

 periods. January to March inclusive was dry, with a deficit 

 for the three months of 2*77 inches. April to September 

 inclusive gave a surplus of 2*03 inches. The third period, 

 October to December inclusive, gave a deficit of 1*80 inches. 

 The total deficit of the year works out at 2*54 inches. 



If, instead of considering Hauteville only, we take the 

 whole six stations, we find that the averages give the same 

 periods, but that owing to the smaller rainfall of the island as 

 compared with the town, the differences are as follows : — 

 1st period, deficit 3*24 inches instead of 2*77 inches ; 2nd period, 

 a surplus of 1*61 inches instead of 2*03 inches ; and 3rd period, 

 deficit of 2*81 inches instead of 1*80 inches. The deficit for 

 the year being 4*44 inches instead of 2*54 inches for Haute- 

 ville. 



It will be remembered that each year since the commence- 

 ment of the comparative tables I have found and corrected the 

 factor needed to adapt the town figures to the ascertained 

 rainfall of the whole island. It will be necessary to do this 

 for a period of 20 years, out of which but six have elapsed. 

 I, therefore, must content myself with the statement that the 

 difference between the town and the whole island now stands 

 at 2*37 inches. This is a smaller difference than I have shown 

 before, and it is quite possible that in wet years, or after a 

 series of wet years, the difference may sink to even a lower
