2. Improvement of Old Pasture {Broad Mead and Long 
Mead), 1904. 
Broad Mead was grazed throughout the year, but Long 
Mead was hayed. The last application of manures was on 
April 3, 1903. The grass was cut on June 28, and carted 
on June 30. The weights of hay are given in Table VIII., 
below.

All the plots showed some small gain on the unmanured 
produce, and in the same direction as the results of 1901 
(Journal, Vol. 63, page 326), superphosphate giving rather 
the highest produce, though the herbage was considerably 
rougher than on plot 4 (basic slag). 
Potato Experiments {Butt Close), 1904. 
The experiment with potatoes in 1904 was a manurial one, 
it being considered desirable to try the relative values of 
kainit and sulphate of potash as suppliers of potash, and 
of nitrate of soda and sulphate of ammonia as nitrogenous 
manures. The variety chosen was “ Up-to-date.’' Twelve tons 
of dung to the acre were carted out and spread in the drills
