342 Report on the Field and Feediny Experiments at Wohurn. 
It will be seen that the barley crop on plot 1, after mangolds, 
manured with dung from 1000 lbs. of decorticated cotton-cake, 
produced a few bushels more corn than on plot 2, manured with 
dung resulting from the consumption of 1000 lbs. of maize- 
meal ; but the differences in the amount of produce on plots 1, 2, 
and 3, on the whole, are inconsiderable. On the other hand, nitrate 
of soda applied at the rate of 124 lbs., or little more than 1 cwt, 
per acre, had the effect of producing an increase of about 12 
bushels of head-corn and nearly 7 cwts. of straw over the pro- 
duce of plot 1, after mangolds grown with cotton-cake dung. 
Rotation No. 3, commencing 1878. — Area under experiment, 
four acres. 
Previous Cropping. — Seeds failed in 1874. Spring tares 1875, 
fed off with 5J cwts. cake per acre. Barley 1876 : produce per 
acre- — dressed corn, 16 bushels ; offal corn, \^ bushel ; straw, 
9i cwts. Barley 1877, with 7 cwts. of rape-cake per acre : 
produce per acre — dressed corn, 41| bushels ; offal corn, 43 
lbs. ; straw, 25^ cwts. 
Seeds 1878. — The four acres of clover and rye-grass have been 
fed off by sheep during the summer, and the land is now sown 
with wheat. On one acre 672 lbs. of decorticated cotton-cake 
have been consumed ; on a second acre, 728 lbs. of Indian corn- 
meal ; and the third and fourth acres were separately eaten off 
without any purchased food. On each of the four acres 10 sheep 
were put on in the beginning of May, and kept on the seeds 
until the 24th of July, when each lot was weighed and sold off. 
On the 10th of September the clover-seeds were again sufficiently 
advanced in growth to afford food for a fresh lot of sheep. On 
each acre 10 sheep were maintained until the 14th of October, 
one lot receiving cotton-cake, a second maize-meal, and the two 
remaining ones were fed upon clover-seeds only. 
As there was still a fair bite of seeds after the sheep were 
taken off on the 14th of October, 5 more sheep were put on each 
acre of seeds, and kept thereon for a week. 
The sheep which had cotton-cake and maize in addition to 
green clover, consumed on an average about ^ lb. of eake or 
meal per day. 
The first lot of sheep going over the clover twice, and kept on 
the seeds from the 2nd May to the 24th of July, in that period 
of 12 weeks yielded the following increase in live-weight:
