- suffered most, and the crops were much laid in July ; but the 
ripening and harvest periods were more favourable. Still, the 
crop was estimated at much below the average in quantity, and 
considerably, though less, below the average in quality. Owing 
to the drought of the previous summer, and the frosts of the 
winter, the land was in a very healthy condition for spring- 
sowing ; the weather was favourable in March, and spring crops 
were generally well got in. Barley was throughout the early 
portions of the season generally pronounced to promise well. 
Later, the heavier crops were a good deal laid ; but at harvest 
the aggregate crop was concluded to be considerably over the 
average in quantity, and, for the most part, of fair, or even of 
good quality. Oats, on the other hand, were more generally 
less promising ; injury from wire-worm was not unfrequent, and 
eventually the crop was estimated at under average. 
In the experimental wheat-field the produce of both corn and 
straw was, by farmyard-manure, notably above the average of 
28 years ; but, without manure, and under nearly all conditions of 
artificial manuring, it was in a greater degree below the average, 
and proportionally more deficient in corn than in straw. The 
exception was the plot with mineral manure and nitrate of soda, 
which gave more than the average produce of straw, and propor- 
tionally less deficiency of corn, than the other artificial manures. 
The weight per bushel of corn was also considerably below the 
average in all cases excepting with farmyard-manure and the 
mixture of mineral manure and nitrate of soda. The following 
results were obtained in the experimental barley field: —
