pedagogy which are adapted especially for teachers in rural and 
elementary schools. Many of the courses in the State institutions are 
free to residents of the State except for the cost of necessary textbooks 
and postage charges. Others of the State schools charge small fees, 
the highest being $5 per course. The tuition charges in the private 
correspondence schools are generally about $20 to $25 for the com- 
plete courses, and frequently the necessary textbooks are furnished. 
The plan of work in the correspondence courses is in general the 
same. Certain parts of the textbooks or bulletins are assigned to be 
studied, and when these have been read the student is required either 
to outline the contents of the assignment or to fill out certain ques- 
tion blanks as a kind of examination on the lesson. These written 
outlines or reports are then mailed to the school, where mistakes are 
checked up and corrected either by letter or by marking on the 
report references to the page of the text where the correct statement 
is found, the corrected report being then returned to the student. 
In a few instances the student is required to perform simple experi- 
ments in addition to the textbook studies. 
Below is a list of institutions from which correspondence instruction 
in agriculture may now be obtained. Most of the State schools 
accept for enrollment nonresident students, though in several instances 
the fees are higher for persons not residing in the home States.
