barley drilled at the rate of 9 pecks per acre on April 2. The 
crop, as on the upper half, was an excellent one, a few warm 
days early in September just ripening it off nicely. As this 
rotation had not yet come under regular experiment, each plot 
produce was not separately weighed, but the whole produce 
of plots 5, 6, 7, and 8 was taken together, this giving an 
average of 49‘3 bushels per acre, of 54*5 lb. weight per 
bushel. Considering especially how very little manure this 
rotation has received of late years, such a return points clearly 
to the paramount influence of “ season ” as against that of 
manuring. The produce was within 6 bushels of the highest 
produce of the manured plots on the upper half of this 
rotation. 
Rotation IV. 1907, Wheat. 
As the swedes of 1906 were being fed off on this rotation 
by sheep (without cake or corn), it was necessary to sow spring 
wheat here. On March 7, 9 pecks per acre of “ Nursery ” 
wheat were drilled ; this came up fairly, but the crop was very 
late in ripening, and could not be cut until September 20. It 
was thereafter threshed and weighed as a whole, and yielded 
an average of 30*9 bushels per acre, of 62‘75 lb. weight per 
bushel. 
Green-Manuring Experiment {Laksome Field), 1907. 
1907 was the year for the green crops, to be followed by 
wheat. Winter tares (ten pecks per acre) were drilled on 
October 22, 1906, on plots 1 and 2, and mineral manures 
(superphosphate and sulphate of potash) were put on plot 1, 
November 3. Rape (4 lb. per acre) on plots 3 and 4, and 
mustard (20 lb. per acre) on plots 5 and 6, were drilled on 
May 28, 1907, and the mineral manures applied to plots 1, 3, 
and 5. The first crops were ploughed in, the tares on July 2, 
the rape and mustard on July 23. All three crops were again 
sown on August 8, and ploughed in for the second time on 
October 1, after which wheat was sown over the whole area. 
Nitrate op Soda and Salt for Mangolds 
{Butt furlong), 1907. 
This experiment, previously carried out on other fields of 
the farm in the years 1905 and 1906, was repeated in 1907, on 
Butt Furlong, the soil of which is of distinctly light and sandy 
character. Indeed, there is in this field a sand pit from which 
sand is regularly carted. The manurial treatment was just the 
same as in previous years. About 15 tons of farmyard manure 
per acre were given to the land on April 15-20, and “ Yellow
