(b) Series D. 1912, Swedes ; 1913, Barley. 
The swedes grown in 1912 were partly removed, leaving 
12 tons to the acre to be fed on the land. This was done by 
sheep which consumed first the roots on the corn-fed portion 
and then passed on to the cake-fed portion. The sheep were 
on the first-named plot from February 3 to March 9, during 
which time they consumed, per acre, 4 cwt. of barley, 4 cwt. 
of oats, and 2 cwt. of mixed oat-straw and clover-hay chaff. 
After passing on to the second portion, they were fed from 
March 9 to April 1, consuming, per acre, 4 cwt. of linseed cake, 
4 cwt. of cotton cake, and 2 cwt. of oat straw and clover-hay 
chaff. The land was then ploughed, and on April 3, 1913, 
Chevalier” barley was drilled at the rate of 9 pecks per acre. 
The crop was cut August 29 to September 5, and was threshed 
out on September 17. The results are given in Table IY.

It will be seen that the corn-fed plot produced 2*2 bushels 
more corn and 2 cwt. 1 qr. more straw per acre than did the
