Report of Experiments on the Growth of Wheat. 121 
Tenth Season, 1852-3. 
October and November (1852) were very wet, and, the latter 
month particularly, very unseasonably warm ; December and the 
first half of January (1853) were also unseasonably mild with a 
good deal of rain ; the rest of January, February, and March, 
were very cold with a good deal of east and north-east wind, and 
some snow ; April and May were for the most part cold and 
wet, with the exception of a short period in the middle of each 
month ; June variable, with a good deal of rain and cold wind ; 
the greater part of July was excessively wet with low tempera- 
tures, but the end of the month and the beginning of August 
were fine ; the remainder of August and September were dull, 
unsettled, wet, and cold. Both the dew-point and degree of 
humidity of the air were generally, and especially the latter, 
sometimes considerably below the average in June, July, August, 
and September. 
t In consequence of the very unfavourable seed-time the breadth 
of land under wheat was much reduced, and the crop of 1853 
was reported to be far inferior to that of any season for many 
years past. 
In the experimental field it was found impossible to work the 
land, an<l sow the manures and seed, until February and March, 
1853. The following is an abstract of the results obtained from 
this spring-sown crop : —
