388 RAINFALL OF GUERNSEY. 



short distance apart. (Tuernsey itself attbrds frequent exam- 

 ples of this, and a ('()m])arison of the measurements made in 

 the other islands during showery Aveather naturally reyeals *^he 

 same sort of thing. Jamiary 3rd, 1907, is a good illustration. 

 On that day a strong to a gale W. to N. W. wind was blowing, 

 showers were Hying about, and yet Alderney escaped them 

 altogether, while Sark got a rainfall of 0*20 in. and Herm of 

 0*01 in. only. In Guernsey on that day the differences were 

 yery marked ; at I'Ancresse 0*08 in. was recorded, while 

 0*25 in. fell at St. Sampson's. A snowfall on the 30th ranged 

 from 0*02 in. at Alderney to 0*12 in. at Sark. In this island 

 0*21 in. fell at Les Blanches. Another and slighter snowfall 

 on February 3rd gaye 0*09 in. of Avater at Alderney, only 

 0*02 in. at Herm and none at vSark. Roughly one inch of 

 snow yields 0*08 in. of water. 



The delightfully fine and dry weather of the last fort- 

 night of March commenced one day earlier at Sark than in 

 the other islands, where fifteen rainless days occurred against 

 fourteen at Herm and Alderney. The return of unsettled 

 Aveather on April 2nd proyed the beginning of many weeks of 

 imseasonable rainy weather. In the second Aveek of April a 

 depression passed from south to north across the Channel 

 Islands, recurved and passed southward again. The depression 

 hoyered near us for a period of fiye days, from the 1 1th to the 

 loth, and gaye altogether 0*91 in. of rain at Sark, 0*85 in. at 

 Herm and 0*84 in. at Alderney, a yery equally distributed 

 rainfall as far as the smaller islands are concerned. 



On May 22nd a strikingly erratic rainfall was reported, 

 yiz., a quarter of an inch at Sark and Alderney and three- 

 quarters of an inch at Herm I At Guernsey the heayiest fall 

 reported to Mr. Collenette Avas from I'Ancresse Avhere oyer 

 half-an-inch (0'62) fell. The difference in the returns from 

 Sark and Herm (half-an-inch) is unusual, but the type of 

 Aveather at the time being thundery no doubt accounts for the 

 observed differences. I may add by the Avay that at St. 

 Aubin's, Jersey, 0*06 in. only Avas measured for that day, and 

 at Portland Bill across the Channel 0*13 in., AAdiich seems to 

 point to the rainfall of May 22nd having been concentrated 

 oyer the Bailiwick of Guernsey. 



On July 3rd and 4th much more rain fell at Sark than in 

 the other islands, yiz., 0*73 in. against 0*39 in. only at Herm 

 and 0*28 in. at Alderney. Jersey had oyer one inch for the 

 tAvo days, and the heayiest fall at Guernsey Avas 0'49 in. at the 

 Grange. .Vlderney reported a heayy thunderstorm on the 

 22nd July Avith 0*21 in. of Avater ; the other islands escaped
