CHAPTER IV. 
ECONOMIC BOTANY. 
Economic Botany 1 is the study of plants from the point 
of view of their uses in the arts, manufactures, or commerce. 
It is largely bound up with agriculture, chemistry, political 
economy, and other subjects. We shall deal with it here 
almost solely from the botanical side. As yet the subject 
is too much in the stage of a heterogeneous assemblage

is intimately connected with Agriculture, & c. The following are 
among the more important works of reference on the botanical side :
