Remarhs. 
As regards the fall of rain, the years 1848 and 1849 have been of a totally opposite 
character ; for, whilst 1848 was by much the wettest, the year 1849 is the driest which 
has occurred since these experiments were begun in the summer of 1844. In 1849, 
the vales of Seathwaite, Langdale, Gatesgarth, Buttermere and Loweswater, have re- 
ceived less rain than the average of the four previous years by 20’90 inches, 18’85 
inches, 24*36 inches, 20*88 inches, and 17’65 inches respectively; and 35*42 inches, 
22*55 inches, 36*46 inches, 27’86 inches and 21*38 inches respectively, less than in the 
excessively wet year 1848. 
It is a remarkable fact, that whilst from one-fourth to one-seventh less rain than usual 
has descended in the valleys generally, Wastdale Head has obtained nearly half an inch 
more than its average quantity*. It will be observed that the south-west wind has 
prevailed to an unusual extent in the past year. The south-west is the predominant 
wind in nine months of 1849, and in the other three months it has been the same 
current which brought the rain. Now, whereas the valleys in general open out to- 
wards the north-west, the Vale of Wastdale directly faces the south-west, and a cur- 
* The rain was read off and recorded by the same registrar as in former years, and there can he no doubt of 
the correctness of the returns. That this instrument must have been attended to with the greatest regularity, 
is evident from the fact of there having been 236 measurements of rain at Wastdale Head in 1849, a number 
considerably exceeding the wet days at any other station, so that the smallest appreciable portions must have 
been recorded.
