REPORT ON PHENOLOGICAL PHENOMENA OBSERVED IN 

 HERTFORDSHIRE DURING THE YEAR 1905. 



By Edward Mawley, F.R.Met. Soc, F.E.H.S., V.M.H. 



Read at Watford, -Ind April, 1906. 



All parts of the county are well represented with the 

 exception of the north-east portion, which unfortunately still 

 lacks an observer. During the past year the Society has lost 

 two of its phenological observers, one at Watford and another 

 at Hatfield, but as there were previously two observers in both 

 localities, the number of observing stations remains the same as 

 in the last report. 



The following table gives the list of observers, the districts 

 they represent, and the approximate height of the stations above 

 sea-level. Three of the stations are just outside our county 

 boundary, Harefield being in Middlesex, Chesham in Bucks, and 

 Odsey in Cambridgeshire. The sequence is from south to north. 



The Winter of 1904-5. 



There have been in this county only four warmer winters than 

 this in the last nineteen years. The only cold period occurred 

 about Christmas and lasted nine days, and at no time did the 

 exposed thermometer at Berkhamsted show more than 15 degrees 

 of frost, which is an exceptionally high extreme minimum for the 

 quarter. A good deal of rain fell during the first half of 

 December, but after that time the weather continued remarkably 

 dry vmtil nearly the end of the season. This was not only 

 a very warm and dry winter, but also an exceptionally sunny 

 one, the duration of bright sunshine at Berkhamsted exceeding 

 the average by as much as twenty-three minutes a day.
