average ones for the season, in excellent condition, but lacking 
in strength. 
Rotation II. 1908, Barley — after roots fed off. 
The swedes grown in 1907 were fed off on the land by 
eighty sheep from January 25, 1908, to the middle of March, at 
the rate of 12 tons per acre. On each plot a little clover hay 
chaff was given, and the sheep had as additional foods, on 
plot 1, decorticated cotton cake at the rate of 920 lb. per acre 
(being \ lb. per head daily), and, on plot 2, maize meal at the 
same rate, the sheep on plots 3 and 4 receiving neither cake 
nor corn. 
The land was ploughed March 19-28, and “ Chevalier ” 
barley drilled on March 31 at the rate of 9 pecks per acre. 
The barley came up well, and the plots presented a great 
contrast to the adjoining ones of the continuous barley- 
growing series. Further, the several plots showed clearly 
the influence of the manurial treatment, the decorticated cotton 
cake plot being by far the heaviest, and the maize meal plot 
coming next. The crop was cut on August 27, and carted and 
stacked September 7-8. The results are given in Table IY.

The barleys were in far better condition than those grown 
on the continuous plots, and were reckoned as above the average 
for the season. 
Rotation III. 1908, Green Crop {Mustard) — after 
Barley (1907). 
The land was ploughed early in January, 1908, and in 
February two tons of ground lime per acre were given to this 
half of the rotation. Mustard was drilled on June 28 and 
came up well. It was cut, carted, and weighed green Sep- 
tember 28-30; The weights are given in Table V.
