136 Report of Experiments on the Growth of Wheat. 
at the beginning and end of the month, but with fine and warm 
weather intermediately. 
The winter of 1861-2 was, therefore, upon the whole, mild ; 
but the spring and summer were almost throughout wet, cold, 
and stormy. The wheat-crop of the country was almost uni- 
versally reported to be under the average, in many cases root- 
fallen, and also much mildewed. 
The following results were obtained in the experimental 
field :—

The experimental crops, without manure, with farmyard 
manure, and with the mixed mineral manure in conjunction with 
all but the most excessive amount of ammonia-salts, were fully 
equal in amount and quality of grain, and not much deficient in 
straw, compared with the average of the 12 years. But with 
mineral manure in conjunction with the very excessive amount 
of ammonia-salts, the produce of both grain and straw was con- 
siderably below the average. Notwithstanding the wetness of the 
most growing periods of the season, the prevailing low tempera- 
tures seem to have been adverse to the production of full amounts 
of gross produce ; but the ripening period seems to have been 
not so unfavourable to the development of grain where there was 
moderate luxuriance of growth, and the crop was not too much 
laid ; which, however, according to the reports, was the case
