348 Report on the Field and Feeding Experiments at Wohurn. 
ficials the equivalent of the dung produced from the consump- 
tion of 672 lbs. of decorticated cotton-cake in the case of plot o, 
and of 728 lbs. of maize-meal in that of plot 4. To plots 1 and 
2 no more manure was applied at all. The land had to be 
thoroughly twitched and hoed early in April. No perceptible 
difference was observed on any of the plots, as all looked very 
strong. On April 30th the acre manured with the heavy dose 
of nitrate of soda (plot 3) was the most luxuriant, next to it 
coming the cotton-cake plot (plot 1). The wheat continued to 
show a splendid crop, but was much beaten down in July on all 
the four plots. The wheat was cut on August 8th, carted on 
August 14th and stacked. Threshing was done in the field on 
October 22nd, the straw being then weighed, and the corn on 
the 29th. 
The results are given in Table IV., p. 349. 
Practically the same result was obtained from maize-meal, 
whether applied as dung or as artificial manure, the yields being 
higher than those from decorticated cotton-cake in either form. 
The lowest yield came from plot 3, and it is worthy of notice 
that the barlev crop of 1882, in this same rotation, was poorest 
on plot 3, and also that the wheat crops of 1882 (Rotation 1) 
and 1883 (Rotation 3), which had undergone similar treat- 
ment to the present wheat crop, were poorest on this same 
plot. 
Rotation No. 3. — Four acres. 1878, seeds ; 1879, wheat ; 
1880, mangolds; 1881, barley ; 1882, seeds ; 1883, wheat. 
Swedes, 1884. — The land upon which wheat had been grown 
in 1883 was ploughed up on Nov. 19th, 1883. 
Dung to be applied to the swedes was made by 8 bullocks, 
which began the experiment on Dec. 18th, and finished, 
Nos. 3, 4, 5, and 6 on Feb. 15th, and Nos. 1, 2, 7, and 8 on 
Feb. 19th. 
The food consumed by the bullocks was as follows : — 
For Plot 1. (2 bullocks.) 923 lbs. of decorticated cotton- 
cake, 5000 lbs. of mangolds, 1250 lbs. of wheat-straw 
chaff. 
For Plot 2. (2 bullocks.) 1000 lbs. of maize-meal, 5000 lbs. 
of mangolds, 1250 lbs. of wheat-straw chaff. 
For Plot 3. (2 bullocks.) 5000 lbs. of mangolds, 1250 lbs. 
of wheat-straw chaff. 
For Plot 4. (2 bullocks.) 5000 lbs.- of mangolds, 1250 lbs. of 
wheat-straw chaff. 
Each set of 2 bullocks received alike 1880 lbs. of wheat-straw 
chaff in addition, as litter.
