manures could not be exceptionally large. Sulphate of ammonia 
in such a dry year did not equal nitrate of soda in its results. 
The highest yield was where 2 cwt. nitrate of soda per acre was 
used in conjunction with superphosphate and muriate of potash, 
viz. 49 bushels. Judging from plot 7, minerals would seem to 
have helped the produce. Though plot 3 gave the highest and 
an excellent return, the best-paying one was from plot 1(1 cwt. 
nitrate of soda, and 2 cwt. superphosphate). In last year's 
similar experiment, 2 cwt. superphosphates, 1 cwt. nitrate of 
soda, and f cwt. muriate of potash per acre did best. The 
results this year differ, therefore, only in respect to the advan- 
tage of using the additional small quantity of potash-manure.

In this case white turnips was the crop drawTi off. Mr. 
Cooke here carried out a plan which both he and I had, for some 
time previously, had in contemplation, viz. by experimenting on 
land which was known from previous experience to require 
potash, to ascertain in what foiTQ it could be best supplied. In 
the combinations of potash used on plots 1, 2, and 5, approxi- 
mately the same quantity of potash (Kfi) per acre (about 56 
lbs.) was applied in each case ; a rather less amount was given 
to plot 6 (49 lbs.), and a double amount (112 lbs.) to plot 7.

The barley was sown on February 16, the mineral manures 
being put on the day before, and nitrate of soda as a top-dress-
