Report on the Field and Feeding Experiments at Woburn. 245 
This concludes the second four-course rotation of No. 3. 
Rotation No. 4. — Four acres. Ib78, mangolds ; 1879, barley ; 
1880, seeds ; 1881, wheat ; 1882, swedes ; 1883, barley ; 1884, 
seeds. 
Wheat, 1885. — The seeds sown among the barley of 1883 had 
been eaten off by sheep, which consumed on plot 1, 672 lbs. of 
decorticated cotton-cake, as additional food ; on plot 2, 728 lbs. 
maize-meal ; but on plots 3 and 4 no additional food. On 
October 20th, the land was ploughed ; and on the 28th, 8 pecks 
■of Browick wheat to the acre were drilled. Mineral manures 
were sown on plots 3 and 4 on November 7th, and nitrogenous 
top-dressings on the same plots on March 28th, these artificial 
•manures being the equivalents of the decorticated cotton-cake 
■dung and maize-meal dung respectively. The wheat was in 
ear about June 20th, and looked remarkably strong. It was cut 
August 24th and 25th, and carted on the 25th and 26th. The 
yield is given in Table IV., page 246. 
Here, again, as in Rotation 3, we have strong evidence in 
support of the view expressed as to the production of a maxi- 
mum crop by means of the maize-meal alone as additional food, 
the produce on this rotation being 10 bushels higher than was 
obtained on the best plots in the continuous wheat experiments. 
Rotation 1. — Four acres. 1885, peas and tares. On com- 
mencing a new rotation, it was decided, in consequence of the 
superiority of decorticated cotton-cake over maize-meal not 
having been brought out in the rotation experiments, probably 
on account of the large amount of unexhausted manures in the 
soil, to alter the plan of carrying on these experiments. With 
the view of exhausting the soil of this supposed over-fertility, 
and also to continue side by side the original enquiry, it was 
resolved to divide each rotation, and to grow on one-half of 
the land a crop in rotation without manure and to be carted off 
entirely, but on the other half feeding off a crop with decorti- 
cated cotton-cake and maize-meal, as additional foods respec- 
tively. Accordingly, the four plots of rotation 1 were divided 
by a cross path into 8 plots of half an acre each. Since barley 
was the crop grown in 1884, the land would in 1885 have come 
in for seeds, but none having been sown among the barley, the 
only plan was to plant over the 2 acres, comprising one-half of 
the rotation, white peas at the rate of 'J pecks to the acre, growing 
them without manure, and on the other half of the rotation (2 
acres) spring tares at the rate of 9 pecks to the acre. This was 
accordingly done on April the 6th and 7th. Both crops came 
up well, but the prolonged drought which followed, together 
with blight, completely spoiled them, and, unfortunately, 
rendered the results obtained not worth recording.
