120 Report of Experiments on the Growth of Wheat. 
spring dry, cold, and backward; the early summer rainy and 
cold, and the maturing period variable, with a good deal of hot 
weather, and some heavy storms. 
The wheat-crop was reported to be generally not deficient in 
bulk, but in many districts much blighted, mildewed, and grown, 
the result being a yield considerably below the average. 
In the following Table is given such a selection of the experi- 
mental results as will best illustrate the influence of the season 
* on the productive effects of the different descriptions of manure 
employed ; and all future summaries given to illustrate the 
characters of the seasons will relate to the produce of the same 
plots.

The unmanured produce of grain was the lowest yet obtained, 
and below the average of the 20 years. The effect of a given 
amount of ammonia-salts, whether alone or in conjunction with 
mineral manure, was very much below the average, especially so 
far as the production of grain was concerned, and where large 
quantities were used. Even the produce of straw was con- 
siderably below the average obtained under like conditions of 
manuring ; but much more so where the small than where the 
large amounts of ammonia-salts were employed. The weight 
per bushel of dressed corn was also throughout very low, but 
especially so in the case of the heavier crops. 
Upon the whole, the produce of the experimental field was the 
worst yet obtained.
