126 Report on the Field and Feeding Experiments at Wohurn, 
The wheat was cut between the 31st of August and the 6th 
of September, 1880, and carted between the 11th and 20th of 
September, and threshed out in the field on the 4th of November. 
The straw and chaff were weighed on the field at the time of 
threshing, and the corn was kept in labelled bags in the granary 
until the 20th of November, when it was weighed and measured, 
each bushel being weighed as a check of the gross weight of 
corn of each plot. 
The Table on page 125 shows the results that were obtained. 
The wheat-crop looked strong and healthy and promising in 
spring, but the long-continued rains and cold weather in the 
latter part of July and in August had a very bad influence and 
prevented the corn from filling up and properly ripening. 
In 1879 the produce on the four rotation acres varied from 
35 J bushels to 37 "9 bushels, weighing only from 54 to 54 J lbs. 
per bushel. In 1880 the produce amounted only to 20 to 
24 bushels, weighing not more than 51 lbs. per bushel, or less 
than the average weight of a bushel of barley grown in 1880 
in rotation No. 1. 
It will be observed that the highest manured plots — 1 (decor- 
ticated cotton-cake) and 3 (artificials equivalent to fertilising 
matters in the cotton-cake) — yielded less corn than the two plots 
which were not manured with so large a proportion of nitro- 
genous fertilising matters. 
This is specially noticeable in the case of plot 3, which 
received in spring a top-dressing of 275 lbs. of nitrate of soda. 
Whilst the nitrate of soda produced nearly 2 tons of straw, it 
gave only 20 bushels of very light wheat, or about 4 bushels 
less than plot 2, upon which the seeds of the previous year had 
been fed off by sheep consuming maize-meal. 
It thus appears that in cold and wet seasons like that of 1880, 
and on light land, highly manured wheat, and more especially 
wheat top-dressed in spring with nitrate of soda, does not yield 
so well as, and produces more straw in proportion to corn than, 
wheat not so highly manured with nitrogenous fertilisers. 
Rotation No. 3. — 1878, seeds; 1879, wheat; 1880, roots; 
1881, barley. 
Mangolds, 1880. — The requisite quantity of dung for the 
rotation mangolds was made by 8 bullocks, 2 of which, in 
addition to mangolds and straw-chaff, consumed 1000 lbs. of 
decorticated cotton-cake, 2 others 1000 lbs. of maize-meal as an 
additional food ; the 4 remaining bullocks were fed upon 
mangolds and straw-chaff only. 
The bullocks were put up in the feeding-boxes on the 4th of 
March, and by the 2ist of April they had consumed the food 
required for producing the dung for the 4 acres of the rotation
