1914.] BAILIWICK RAINFALL. 145 



The rainfall measured at the three stations after the storm 

 was : Guernsey 0*10 in. ; Sark 0*60 in. ; Alderney 0'73 in. 

 The week ending Saturday, July 11th, and which includes 

 the above thunderstorm rain, was one of unusually variable 

 rainfall over the Bailiwick as shown by the totals given below. 



Guernsey 0*44 in. ; Sark 0*85 in. ; Alderney 1*34 in. 



To Captain Henry and to Sark belong the honour of 

 recording the first inch rainfall of the year ! This fell on 

 Sunday, July 19th, and was not a thunderstorm downpour. 

 Alderney came off best on this occasion. For how many 

 hours the rain poured down at Sark and Alderney we do not 

 know, but at Guernsey the fall lasted six hours — from 3 to 9 

 p.m. — during most of which time the Avind was strong and 

 squally from S.E. The measurements were : 



Guernsey (Les Blanches), 0*83 in. ; Sark, 1*04 in. ; Al- 

 derney, 0*58 in. 



A slight thunderstorm passed over Guernsey and Sark 

 during the afternoon of July 22nd and gave 0*28 in. of rain 

 in both islands. At Alderney that day no less than O70 in. 

 fell, but we cannot say whether in association with an electri- 

 cal disturbance or not. Probably it was. 



In July Guernsey was by far the driest of the three 

 islands where a total rainfall of 2*48 in. was measured at Les 

 Blanches against 3*12 in. at Sark and 3*18. in. at Alderney — 

 a curious reversal of the usual conditions. 



August 12th and 13th, two hot days, the latter espe- 

 cially so with max. and mean temperature of 79*0 and 70*0 

 deg. respectively, were followed on the 14th by a severe 

 thunderstorm in all the islands. At Guernsey where it pre- 

 vailed from 5 to 9 p.m. rain fell very heavily, as much as 1*54 

 in. being measured at Les Blanches and 1*84 in. at the Guille- 

 Alles Library. Houses on the Fort Boad were struck by 

 the electric fluid and serious damage by flooding was done in 

 several places. The storm gave 0*91 in. of rain at Sark and 

 0*97 in. at Alderney and, as usually happens, very effectively 

 cooled the air. A paragraph in the Evening Press of the 

 17th thus described the disturbance at Alderney : 



"A severe thunderstorm broke over the island from the south 

 west on Friday evening, and lasted to near midnight. Much rain fell, 

 the lightning was almost continuous, and the hill -side roads were in 

 many places guttered and denuded of sittings. An operator at the 

 Esses Hill telephone was paralysed. The full strength of the storm 

 spent itself in the Channel." 



Favourable weather prevailed at Guernsey for obser- 

 vation of the partial eclipse of the sun on Friday, August 

 21st. A sensible reduction of light was noticeable at the
