each month, rising according to the number of inches. The 
scale for the Forties runs from 0 to 32 inches; the Fifties, 26 
to 60 inches; the Sixties from 50 to 82 inches ; the Seventies 
from 72 to 110 inches, and the Eighties from 100 to 135 
inches. 
York occupies a most typical “ Central Plain ” region, the 
position of the Ouse corresponding in miniature to the Mississippi, 
east of the great American “ Divide.” Thus it forms a good 
basis for comparison for North-East England. Its rainfall has 
varied from 1742 inches in 1887 to 39'85 inches in 1872, with 
a mean for this fifty years of 25 005 inches. Days with 
enough rain to measure (0 - 005 or over) have ranged from 117 
in 1855 to 222 in 1877, the average being 1706. 
Table I. shows that ours is a summer and autumn fall, the 
former thanks to heavy showers, the latter because of frequent 
wet days January to April are about equally dry ; July to 
October pretty equally wet. There is, however, a fall off in 
September, which would be more marked were it not for the 
exceptional wetness of this month during the Seventies, and 
the even more exceptional dryness of July in the Sixties. In 
spite of this the close range of these four months is remarkable. 
Correcting September to 31 days, for comparison, the totals 
shown on plate IV. are, respectively, 133T7, 134 25, 120 13, 
and 13089 The difference of only 3’36 inches between the 
three higher values is extraordinary. Even more so is the 
result up to the close of 1894, which gives August, 146‘95 
inches ; October, 144*50 ; July, 14446, or a range of less than 
2J inches after 54 years September is now 125‘43, which 
“corrects” to 129 60. Curiously, the three driest months 
are also almost equal, namely, February, 83 05 inches; March, 
86 - 93 inches; April, 86 19. Correcting these to April we get 
88 20, 84T9 and 86T9, respectively. The former series is 
more significant when compared with the ten years’ totals 
The difference should then of course be five times less. We 
get, however, this table :—
