APPLICATIONS OF BOTANY 



BoTA]srY is oaie of the very oldest of the sciences and treats 

 of plant life, upon whicli all other forms of life depend ; in fact, 

 it may be called the most fundamental of all sciences. It would

 when the human race took the first step in agriculture, or did 

 it begin with the commerce in plant p'roducts, or did it begin 

 at some later period when some individual began the study of 

 plants for some definite piirpose ? Primitive agriculture is prao 

 tieed by the savage and partly civilized tribes of men throughout

 highest development in the fertile valleys of southern Asia, in 

 the Valley of the ISTile and in southern Europe. When America 

 was discovered, its highest developiment of agriculture was 

 found in Mexico, Central America and the Andes regions of

With the advance of civilization, man gave more and more 

 time to the study of useful plants. The first great and im- 

 portant steps in the study of botany began with the search for 

 medicinal plants. The early works on botany were peculiaj
