CHEMICAL SECTION. 
The following list of analyses was made, consisting 
mostly of selected forage plants, not elsewhere reported in 
this bulletin. The exceptions are the “ wheat weed,” 
the “ poverty weed ” and the “ lemon plant ” or weed. 
These were analyzed with a view to note the constituents 
and their proportions, in order, if possible, to see if this 
would account in part, at least, for the action of these 
in apparently robbing other plants of the food in the soil. 
These analyses seem to indicate that this is true to some 
•extent, at least:
