These ashes were submitted to analysis and the results 
are given below, together with an analysis of an alfalfa ash, 
made from plants of first cutting, full bloom. 
The composition of these ashes is as follows : 
Pea Vines

These results show that the pea is a still heavier feeder, 
particularly upon phosphoric acid and ", potash, than the 
alfalfa plant, which, in the aggregate, removes very large 
quantities of these substances. The phosphoric acid in the 
alfalfa ash is quite the maximum found in fifteen samples 
prepared from alfalfa hay, but is less than that in the ashes 
of the pea vines. On the other hand, the sum of the lime 
and magnesia in the ashes of the pea vines is only from one- 
half to two-thirds of the amount found in the various sam- 
ples of alfalfa ashes. The ashes of the pea vines compare 
with those of red clover in the same sense and almost in the 
same degree as with those of the alfalfa. In regard to the 
total nitrogen in the plant, it will be observed that the pea 
vines contain materially more of It than alfalfa does. bTr 
the purposes of green manuring, they are easily and quickly 
enough grown to deserve the attention of our ranchmen. 
They will serve admirably to add organic matter and nitro-
