CONCLUSION, 
The above experiments were not planned with a view to obtain comparative 
resuits as to yields; and where yields have been given they are only incidental. 
‘The main object was to ascertain whether or not a leguminous plant could be 
made to produce tubercles by inoculating it with a soil‘impregnated with the 
right kind of micro-organisms. As the Kansas soil contained none of these organ- 
isms, the conditions were entirely under control, and results obtained which 
otherwise would have been impossible. The results show conclusively that in- 
oculation is entirely possible; and this, taken in connection with the fact that it 
has been repeatedly proven that tubercles are valuable adjuncts to leguminous 
plants, both for yield and as a fertilizer, suggests the practicability of inoculat- 
ing fields deficient in micro-organisms that would be beneficial to the particular 
leguminous crop to be grown. 
When we realize that in the Eastern states many farmers are paying from six to 
ten dollars an acre for fertilizers, which in the aggregate amount toa tax of millions 
of dollars, and as we in the West are fast tending in the same direction, should it 
not behoove us to lay hold of one of nature’s most effective means of maintain- 
ing and even increasing the fertility of the soil? Free nitrogen is around and 
about us in superabundance, it composing four-fifths of the air; but, without 
the aid of these bacteria working within the tubercles of the roots, plants have 
no power to make use of it. By growing leguminous crops in rotation, and 
inoculating the soil when the latter is deficient in the proper species of bacteria, 
and thus controlling the action of these microscopic plants, the farmer may find 
them to be among his best friends and strongest financial supporters.
