6 BULLETIN 346, U. S. DEPARTMENT OF AGRICULTURE. 
Competent supervision essential.—Supervision is necessary in order 
that those in charge may be sure the work is carried out as outlined. 
It is even more essential that some one take an active interest in 
aiding with problems which may arise, and in giving encouragement. 
Where it can be arranged it will prove most satisfactory as a rule to 
have the teacher who is conducting the class work supervise the 
projects connected with the courses given. The summer season is the 
most important time for most projects, hence in States where the 
teaching of agriculture is based upon the home project, teachers are 
employed for the entire year. If any vacation is allowed them it is 
taken in the winter. Effective supervision means frequent visits to 
the homes of the students. In districts where the students are scat- 
tered over a wide area, some special means of transportation will be 
essential to efficient service. 
Detailed records to be kept.—A valuable part of the training secured 
in connection with carrying out a project will be obtained in the 
keeping of accurate records and accounts. It will be helpful, if not 
absolutely necessary, to give a few lessons in elementary cost ac- 
counting before the work is begun. The record should cover points 
learned in connection with study relating to the project as well as 
experience gained in practice. In keeping accounts such items as 
rent of land and interest on investment should not be overlooked. 
Accurate account should be kept of the time expended and charges 
and credits made upon a fair basis. Accuracy and fairness are 
especially important in the keepmg of accounts where there is any 
contest feature in conducting the projects. . 
The following record blank for a potato project may be adapted 
to other crops. It is suggestive of forms which may be used for 
other kinds of projects.
