Report on the Field and Feeding Experiments at Jf'oburn. 343 
show that, even after a lapse of two years, the farmyard-manure 
applied previously to 1882 has left in the land some unex- 
hausted fertilising matters which told upon the produce of the 
wheat crop of 1883. 
Experiments on the Continuous Growth of Barley. 
The land devoted to these experiments was ploughed for the 
first time on September 1st, the ground having been first well 
twitched. Four bullocks, to make the dung for the plots which 
were to receive farmyard-manure, were put into the feeding 
boxes on October 11th, and finished making the dung on 
November 4th. In this period of three weeks and three days 
the bullocks consumed : — 
cwts. qrs. lbs. 
Decorticated cotton-cake 2 2 0 
Maize-meal 4 0 0 
Sliced white turnips 30 0 0 
Wheat-straw chaff (as food) 5 0 0 
Besides which, they used 12 cwt. of wheat-straw chaff as litter. 
The following table shows the weights of the bullocks, sepa- 
rately and collectively, when put in on October 11th, when 
removed on November 4th, and the increase in live-weight 
obtained during the period of feeding : — 
When put in, 
on Oct 11, 1832. 
When removed, 
on Nov. 4.

Total increase 
The bullocks were fed at first with 30 lbs. of roots per day, 
and the other food in proportion, and finished off with 40 lbs. 
of roots per day. With the exception of bullock No. 1, the 
animals increased uniformly. The composition of the various 
foods has been already given on page 338. 
The dung was removed from the pits on November 13th, and 
left covered until January 2ith, 1883, when it was weighed. 
The total weight of dung obtained was 32 cwt. 1 qr. 16 lbs. 
To one half of plot 10 a quantity of dung, calculated to contain 
nitrogen equal to 100 lbs. of ammonia per acre, was applied on
