Both in quantity and quality the wheat crop of this season 
was much below an average. The dunged land, which yielded 
nearly 39 bushels, weighing 60 lbs. per bushels, shows, what 
may be noticed generally throughout the experiments, that 
while the crop upon the dunged land is able to resist the influ- 
ence of bad weather better than those grown by artificial manures, 
it cannot, under very favourable weather, attain the produce 
which is reached by the crops receiving artificial manures. 
The estimated produce of the selected experiments gives 
24 bushels per acre, at 61 lbs. per bushel. 
Twenty-ninth Season, 1871-72. 
October, November, and December, were all months of 
excessive cold, with very little rainfall. Mr. Glaisher observed 
that the quarter had been remarkable for the longest con- 
tinuance of low temperature in November, and the first half of 
December, that had occurred in this century. 
This was followed by nearly three months of very warm 
weather, which lasted until the middle of March. Tlie 17th of
