first 8 years, 3 tons 16 cwts. over the second 8, 4 tons over the 
last 7 years, and 3 tons 8 cwts. over the 23 years. That is to 
say, there was a gradual increase in the amount of dung applied. 
Of artificial manures there- was an increase, both of the mineral 
and of the nitrogenous, over the second period compared with 
the first ; but there was again a reduction over the third period. 
It was found that, under the condition provided by the dung, 
aided by the artificial mineral manures, the application of as 
much as 1 cwt. of nitrate of soda per acre per annum was liable 
to give a too stemmy, and almost exclusively grassy herbage. 
' 336 lbs. of kainit were applied, reckoned to contain about 84 lbs. sulphate 
of potash ; and it would also supply sulphate of magnesia, and chlorides of 
magnesium and sodium.
