Rotation No. 3. — 1878, seeds ; 1879, wheat ; 1880, roots ; 
1881, barley. 
Wheat, 1879. — The seeds were fed off in 1878 by ten sheep 
kept on each of the four acres of this Rotation. On plot 1 
the sheep consumed as additional food 672 lbs. of decorticated 
cotton-cake. On plot 2 they consumed 728 lbs. of maize-meal. 
On plots 3 and 4 no additional food was given ; but on plot 3 
the wheat was manured with artificial manures, containing as 
much nitrogen and other fertilising constituents as the manure 
from 672 lbs. of decorticated cotton-cake, namely, 275 lbs. of 
nitrate of soda, 73 lbs. bone-ash made into superphosphate, 
45 J lbs. sulphate of potash, and 47 J lbs. of sulphate of magnesia. 
And lastly, on the fourth acre (plot 4) the wheat was manured 
with artificial manures containing as much nitrogen and other 
fertilising matters as the manure from 728 lbs. of maize-meal, 
namely, 58^ lbs. of nitrate of soda, 11^ lbs. of bone-ash made 
into superphosphate, 5 lbs. of sulphate of potash, and 8 lbs. of 
sulphate of magnesia. 
The same kind of wheat which was sown in 1877 — Browick 
wheat — was sown on the 2nd of November, 1878, and the 
artificial manures were applied as top-dressings on the 10th of 
March, 1879. Although the seed went into the land when it 
was in capital condition, the cold weather — November and 
December — prevented the plant pushing through the soil for two 
months, for it was not before the 1st of January, 1879, that the 
wheat came up.
