peas) failed, and too much reliance must not be placed on the 
wheat results of 1886, owing to the uneven plant. Still, taking 
together the root crop of 1887 and the previous wheat crop of 
1886, it is clear that the cotton-cake plots produced higher 
results than the maize plots. For instance, plot 1 (cotton-cake) 
has yielded 20^ bushels of wheat and 11 tons of swedes, against 
15^ bushels of wheat and 10 tons of swedes in the case of plot 
2 (maize-meal). Similar differences are observable in the case 
of the other plots, the cotton-cake plots always coming out 
the better. The fact that between the upper half of the field 
(plots 1, 2, 3, and 4) and the lower (plots 5, 6, 7, and 8) there 
was practically no difference in the swede crop, is not to be won- 
dered at, inasmuch as the tares and peas both failed in 1885, 
and, no manure being applied to the wheat in 1886, the treat- 
ment of both halves was thus practically alike. 
Rotation No. 2. — Four acres. 1885, swedes (2 acres), man- 
golds (2 acres); 1886, barley (4 acres); 1887, tares (2 acres), 
peas (2 acres). The peas (Sangster's White, No. 1) were drilled 
on plots 5, 6, 7, and 8, on March 5, 1887, at the rate of 2 
bushels per acre ; and the tares in the same quantity on plots 
1, 2, 3, and 4, on March 10, both without manure. The peas 
were cut and harvested July 23-30, and the tares the first week 
in August. Both lots were thrashed October 18-28 ; the results 
are given in Tables IV. and V. below. 
The crops were not nearly as heavy as those of 1886. It may 
be remembered that it was on this rotation, in the case of the 
barley of 1886, that the first indication of the high yield due to 
cotton-cake as against maize-meal was observable ; and here to
