such a beneficial effect in 1879 as in the preceding year. The 
barley, it will be noticed, weighed nearly as much per bushel 
as the wheat. Considering tlie bad season, botli the Rotation- 
wheat and the Rotation-barley grown on the light Woburn land 
were fine crops, far exceeding the average produce of corn grown 
in England in 1879. 
VII. — An Experiment on the Comjjarative Value of Linsced- 
cake and a Mixture of Decorticated Cotton-cake and Maize-meal 
for fattcnimj BuUochs. By Du. Augustus Voelckek, F.R.S., 
Consulting Chemist to the Royal Agricultural Society. 
On the 3rd of October, eight bullocks (Herefords) were put in 
the feeding-boxes for the purpose of making the requisite quan- 
tity of manure for the experiments on the continuous growth of 
wheat and barley. 
The bullocks, in addition to white turnips and straw-chaff, 
received decorticated cotton-cake and maize-meal. They were 
removed from the boxes on the 9 th of November, and as they 
were in good condition, it occurred to me to try a fattening experi- 
ment, with a view of ascertaining whether it is more profitable to 
give linseed-cake to fattening-buUocks, in addition to roots and. 
chaff, or a mixture of maize and decorticated cotton-cake. 
The same eight bullocks were again put into the feeding- 
boxes, after having been weighed on November the 9th, 1879. 
All were fed upon the same allowance — white turnips, swedes, 
and chaff — in addition to which four bullocks received Indian 
corn-meal and decorticated cotton-cake, in equal proportions, 
and four bullocks linseed-cake. The bullocks were again 
weighed on the 17th of December, and for the last time on the 
17th of January, 1879. Between the 9th of November, 1878, and 
the 17th of January, 1879, one lot of four bullocks consumed : — 
Tons. cwts. qrs. lbs. 
0 16 3 -i of Wheat Chaff. 
0 10 0 0 of White Turnips. 
4 7 2 0 of Swedish Turnips. 
0 18 3 2-1 of Dcc-urticatcd Cotton-cake. 
And 0 19 1 20 of jMaize-meaL 
The second lot during the same period consumed the same 
amount of roots and straw, namely : — 
Tons. cwts. qrs. lbs. 
0 16 3 4 of Wheat Chaff as food. 
0 10 0 0 of White Tundps. 
4 7 2 0 of Swedes. 
And 1 14 1 ,5 of Linseed-cake.
