The term "home project" applied to instruction in agriculture in- 
cludes each of the following requisites: (1) There must be a plan 
for work at home covering a season more or less extended. (2) It 
must be a part of the instruction in agriculture of the school. (3) 
There must be a problem more or less new to the pupil. (1) The 
parents and pupil should agree with the teacher on the plan. (5) 
Some competent person must supervise the work done at home. 
(6) Detailed records of time, method, cost, and income must be 
honestly kept. (7) A written report based upon the record must 
be submitted to the teacher. This report may be in the form of a 
booklet. The club project should be identical with the home project 
from the school point of view. 
A potato project may take one of two different lines. It may be 
a production project where the chief aim is to increase the produc- 
tion per acre at the lowest cost; or it ma}' be an improvement project 
where the aim is to improve, by careful selection, the quality and 
quantity of a variety of potatoes grown. The potatoes produced on 
the first project will be placed on the general market for consump- 
tion, while the surplus crop produced on the second will, after selec- 
tion, be sold to dealers or producers for seed potatoes. The first 
type adapts itself the better to general conditions. 
Correlations. — Some suggestions have been made in connection 
with each lesson, as to the use of this subject in vitalizing the 
other subjects in the curriculum. These correlation suggestions are 
not intended as a part of the lesson in which they appear, but should 
be used with recitations in other subjects. The teacher should seize 
every opportunity to link up the recitation with the life of the com- 
munity and to give the instruction purpose and direction by con- 
necting it with the problems of the home and farm.
