232 BAILIWICK RAINFALL. 



Keepers measured 3*08 in., and at Alderney Mr. Picot's total 

 was 4'21 in. 



Underground water, which began to flow in November, 

 rose rapidly in December, and at the end of the month the 

 spring at Les Blanches was higher than it had been in 

 December for three years. A plentiful supply of water 

 during 1916 seems assured to us. 



In conclusion I have again pleasure in acknowledging 

 the valued help in the cause of rainfall observation rendered 

 by Capt. Henry at Sark and Mr. Picot at Alderney. As 

 already stated Capt. Henry having come to reside at Guernsey 

 the gauge has been transferred from Vallee du Creux to 

 Pointe Robert where it is now in charge of the guardians of 

 the Lighthouse who most kindly undertook to continue the 

 work carried on with such untiring zeal and devotion by Capt. 

 Henry for close upon ten years.
