Among tlie four leguminous species of any distinct prominence at all, this plant 
takes the first place in the greatest number of instances. It was the first of the four 
on 11 plots in 1862, on 10 in 1867, on 12 in 1872, and on 13 in 1877. It was 
second on only one plot in 1862, on three in 1867 and 1872, and on four in 1877. 
It was third on three plots in 1862 and 1867, on two in 1872, and on one only 
in 1877. It, however, yielded more than 5 per cent, of the total produce on only 
two plots in 1862, two in 1867, two in 1872, but on five in 1877. Like its three allies 
it has almost disappeared on most of the ammonia plots; but has even increased 
where the smaller quantity of nitrate of soda was employed, especially when in con¬ 
junction with mineral manure containing potass. Without manure, although the 
actual quantity is small, it has increased rather than diminished; but in a considerably 
less degree than the Lotus, 
The most striking point in the development of Lathy rus on the experimental plots 
is its very great increase where mineral manure, including potass, is used, without 
nitrogenous manure. The table shows that on plot 6, where ammonia salts had been 
applied during the first 13 years, but a mixed mineral manure, including potass (witli-
