132 Report on the Field and Feeding Experiments at Woburn. 
The four bullocks accordingly increased 28| lbs. per week, 
or each gained on an average 7^ lbs. per week. 
On some of the experimental plots the wheat suffered from 
the attacks of wire-worm, and bare places had to be filled up 
by transplanted wheat. By dint of much trouble a fairly 
uniform plant was produced on the several plots, and no expense 
•was spared to keep the land free from weeds, which proved a 
Bvaost difficult task in a wet and bad season like that of 1879. 
The wheat was cut on the 8th of September, and carted and 
thatched on the 17th of September, 1879. 
Directly after the field had been cleared of the wheat, it was 
scuffled and drag-harrowed with a view of killing weeds, and 
ploughed rather shallow on the 15th and IGth of October. 
Threshing in the field by means of a portable engine com- 
menced on the 30th of October, 1879. The straw of each 
plot was weighed in the field, and the corn of each plot bagged, 
carefully labelled, and stored in the granary until the 19th of 
November, when the gross weight of corn from each plot was 
ascertained ; and this weight was checked by measuring the 
produce of each plot, and weighing separately every bushel of 
corn produced on the eleven experimental :^-acre plots. In this 
way the possibility of a serious mistake in taking down the 
weight of corn may be avoided, and at the same time the 
average weight of a bushel of corn may be ascertained more 
correctly than by weighing only 1 or 2 bushels. I may men- 
tion that the differences in the weight of several bushels of corn 
from the same plot seldom varied more than from ^ to ^ lb. 
The weight per bushel in the following tabulated results is the 
average weight of the several separate weights of every bushel 
of corn grown on each plot. There is no need of embodying 
in this report all the figures which were obtained in weighing 
the produce of the experimental wheat-field ; but in order to 
show clearly how close is the agreement of the gross weight 
of corn and the sum of the separate weighings of each bushel 
usually turned out in the wheat and barley experiments in 1879, 
I quote the details obtained on plot 5. 
Weighed with the bags, the corn weighed 379 lbs., bags alone 
9 lbs., leaving the total net weight of corn 370 lbs. Bushelled 
out, the wheat on plot 5 gave :
