Table LIIT. —Relative predominance of Lotus corniculatus . 
Lotus corniculatus was first amongst its few allies on one plot in 1862, on six in 
1867, on six in 1872, and on five in 1877. It was second on two plots in 1862, on 
one in 1867, on six in 1872, and on three in 1877. It was third on four plots in 1862, 
on five in 1867, on none in 1872, but on six in 1877. Notwithstanding this consider¬ 
able predominance among Leguminosae, it only yielded more than 5 per cent, of the 
total mixed herbage on the two unmanured plots, and there only once, viz.: in the 
third separation-year. Like the other leguminous species, it has gone down in a very 
marked manner on all the plots where ammonia-salts were used; but it has done so 
less where these were used alone, and where only poor surface-rooting grasses were 
stimulated against it, and again on plot 18, where only a small quantity of ammonia- 
salts, with a complete mineral manure, was employed. It has been less reduced on the 
plots only moderately manured with nitrate of soda. On the unmanured plots alone 
has it shown any marked increase; but with superphosphate of lime alone, and with 
the mixed mineral manure without potass, it has also shown a tendency to increase 
rather than to dimmish. Where the mixed mineral manure, including potass, is 
applied, it is the more surface-rooting Lathyrus pratensis that prominently represents 
leguminous growth; and it is only where there is no luxuriance of grasses, or of more
