128 JOCENAL OF THE ROYAL HORTICULTURAL SOCIETY. 
the area to which these have reference is but one square yard, they can 
only be regarded as sufficiently close a]5proximations for horticultural 
purposes. Taking a number of years, the average rainfall for each 
square yard per week during the six months ending with September, 
in the different districts into which the Meteorological Office divides the 
British Isles, is as follows : — 
Scot. Scot. Ire. Ire. Eng. Eng. Scot. Eng. Eng. Eng. Eng. Britis 
W. N. N. S. S.W. N.W. E. Mid. N.E. E. S. Isles

I must here express my indebtedness to my friend, Mr. R. H. Curtis, 
of the Meteorological Office, for kindly compiling for me a table giving 
the mean monthly rainfall for each district, which has greatly facilitated 
the preparation of the above and other tables of a similar character. 
It will be noticed that the different districts have been here arranged 
according to their rainfall, beginning with the district which is usually 
the wettest, and ending with the driest (Fig. 48).

Now, taking the same six months for the year under discussion (1898), 
the average weekly quantity of rain which fell on each square yard comes 
out in the following- manner, and shows a deficiency in all but three 
districts as compared with the seasonable amounts previously given : — •
