240 THE WEATHER OF 1906. 



the form of snow. The fall of snow commenced on tliis day. 

 At the Coimty Museum, St. Albans, it was 5^ ins. in depth and 

 yielded 0"45 in. of water ; and at Weetwood, Watford, it was 

 6 ins., and yielded 0-50 in., the yield in each case being 

 one-twelfth the depth of snow, and doubtless this was general 

 over the county. Snow fell at every station on the three 

 following days and on the 30th, and at many also on the 29th. 

 On this day at Berkhamsted its average depth was 8 inches, 

 but at Watford it evaporated or consolidated each day after the 

 25th to the extent of the fall, never being more than 6 inches 

 in depth. The fall of snow was much the heaviest in the 

 Eastern Counties, reaching 12 inches in depth in Norfolk and 

 Suffolk. In the north-east and south-west of England, the 

 western part of Wales, nearly the whole of Ireland, and much 

 the greater part of Scotland, no snow fell. Accounts of the 

 storm over the British Isles are given by Dr. H. R. Mill in the 

 ' Meteorological Magazine,' vol. xH, pp. 224-226, and in ' British 

 Rainfall,' 1906, the latter more fully and with maps showing 

 the depth of snow over the country and the hour at which it 

 began. The 27th was much the coldest day in the year.
