 the last decade there has been an increasing interest in agri- 

 cultural education for the secondary schools. 



The greatest danger to agriculture as a subject for a course 

 of study in high schools has resulted from attempting to make 

 it conform to the organizing ideas of that kind of education 

 that has for its controlling motive formal discipline, instead 

 of making it strictly vocational. The result is that agri- 

 culture is being taught as a textbook subject in too many of 

 the high schools. This is due largely, no doubt, to the fact 

 that there have been no laboratory and field guides in agri- 

 culture adapted to high schools. The controlling motive

 admirably fitted them to prepare a workable manual for
