The difference between these sets is by no means so marked 
as was the case with the wheat crop grown immediately after 
the green-crops had been ploughed in, and it is clear that the 
second corn crop has not materially altered the conclusions 
previously come to as to mustard being, on this particular land, 
a better green-crop to plough in than tares or rape. 
Varieties of Oats. 
It was thought desirable to compare in 1913 certain varieties 
of oats. Among these was “ Banner,” a Canadian oat which 
had been grown considerably in the North of England, and 
which had been extensively tried at the Cockle Park Farm of 
the Northumberland County Council. 
Another variety tried was the New Zealand oat, “ Sparrow- 
bill.” A nice piece of land for the purpose being available on 
Road Piece Field, 4 areas of 1 acre each were marked out and 
sown respectively as follows : — 
Plot 1. — “ Banner ” (Canadian). 
„ 2. — “ Abundance ” (Garton’s). 
„ 3. — “ Sensation ” (Canadian). 
„ 4. — “ Sparrowbill ” (New Zealand). 
The oats were drilled on March 25 and 26, 1913, at the rate 
of 4 bushels per acre, with the exception of “ Sparrowbill,” the 
seed of which appeared to be inferior, and, accordingly, 5 
bushels per acre of it were sown. By April 16 the oats were 
well up with the exception of “ Sparrowbill,” this latter variety
