was most noticeable throughout the season and after the 
removal of the hay crop. There is no doubt that the lime 
has had the effect of producing a finer condition of the 
herbage. Next in order to farmyard manure came the plot 
dressed with basic slag and sulphate of potash (plot 3), this 
showing an increase also in the leguminous herbage. Plot 2, 
however (mineral superphosphate and sulphate of potash), 
was the only one to show a marked increase of leguminous 
herbage, the percentage rising to 4‘5. The growth of clovers 
on this plot had been noticeable throughout the season. 
It is worthy of remark that in 1908 there was a much 
smaller proportion of leguminous herbage in the plots generally 
than had been noted in the years 1905 and 1907, when botanical 
separations were also made. In 1905 the lowest percentage of 
leguminous herbage was 2 - 0 and the highest 7T, in 1907 the 
lowest was 5*1, the highest 190. Now (in 1908) the lowest 
percentage was 0*7, the highest 4'5. 
In Broad Mead field the experiments on the value of sewage 
sludge, undertaken in 1907 for the Royal Commission on Sewage 
Disposal, were continued in 1908. These experiments, when 
completed, will be separately reported on.
