The crop on the decorticated cotton cake plot was somewhat 
the best. 
Rotation IV. 1908, Swedes — after Wheat (1907). 
The land was ploughed in December, 1907. “ Elephant ” 
swede seed — at the rate of 4 lb. per acre — was drilled on 
June 13, 1908, this part of the rotation receiving also 4 cwt. 
per acre of basic superphosphate, and 1 cwt. per acre of 
sulphate of potash. A quite good crop of swedes, considering 
the season, was obtained. These were pulled, topped, and 
weighed November 23 to December 4. The weights are given 
in Table VI.

B.'— LOWER HALF (Bullock-feeding). 
Inasmuch as both the upper and lower halves of the field 
had got into regular rotation, it was now possible to take the 
same crop on the two halves of each rotation ; accordingly 
cultivating, drilling, and reaping could be done right through 
the two halves, thereby economising labour besides adding to 
the interest of the experiment to any one inspecting it. Thus, 
in passing along the middle line, between the upper and lower 
halves, one can compare, on the one hand, a barley crop follow- 
ing roots fed off by sheep with cake or corn, with one following 
roots manured with dung made by the feeding of qake or corn 
to bullocks in boxes ; in like manner the other crops of the 
rotation can be compared as grown under the two sets of 
conditions. 
The cultivations being alike, it is unnecessary, in treating of 
the crops of the lower half, to repeat the details, but it will be 
sufficient to briefly state the results.
