NATURAL DISTRIBUTION. 
In both Europe and Asia Medicago falcata has a very wide distri- 
bution, as the previous lst and accompanying map would indicate. 
(Fig. 1.) The data from which this map was prepared were ob- 
tained from various published floras of Europe and Asia and from 
correspondents and explorers: of the Department of Agriculture. 
The points where the species has been reported in literature as being 
found growing wild are designated, as well as those localities from 
which seed has been collected from plants growing without cultiva- 
tion and sent to this country. To what extent the distribution of 
Medicago falcata’is strictly a natural one can be estimated only 
broadly. However, the chances are very much in favor of the species 
being truly indigenous over a large portion of its present range, with 
the possible exception of western Europe, since its dissemination 
through the agency of man has been very largely incidental. 
Outlining the distribution of Medicago falcata by means of the 
data that are available, it is found to occur in moist western England, 
in Norway to the sixtieth parallel of latitude, and generally through- 
out Sweden. It is common in central and southern Russia and in 
Austria, France, Spain, and other Mediterranean countries. In 
Siberia its range extends north at least to the sixty-third degree of
