board or made into a chart.) Charts showing the composition of 
the potato and its relative food values should also be made. Pictures 
clipped from bulletins, showing types of potatoes, may be mounted 
for class use. The teacher should keep in mind always the value 
of illustrative material in arousing interest and vitalizing the study 
of the subject. Continuous efforts should be made to visualize the 
lessons. 
The survey. — One of the best means by which the teacher may be- 
come informed about the potato interests of the district is the potato 
survey. This survey may be made either by the teacher alone, or 
with the assistance of the pupils, the latter method being more 
easily carried out. The survey should include such questions as size 
of farm acreage in potatoes, soil, varieties of potatoes, yield per acre, 
value, bushels marketed and bushels used- at home, storage methods, 
etc. 
The general district survey as a means of obtaining agricultural 
information and as a basis for agricultural instruction may be set 
forth in the following outline : 
The District Survey. 
The aims — 
To know the district. 
To obtain a basis for teaching agriculture. 
To interpret better State and national data. 
To observe progress by successive surveys. 
To provide vital correlation material. 
The method — 
Preparation of adequate lists of questions. 
Collection of data, all farms, each pupil. 
Tabulation of data by farms. 
Summary of tabulations. 
Mapping survey data. 
Utilization as — 
Basis of class instruction in agriculture. 
Problems, reports, and other correlations. 
Means of developing home projects. 
Entering wedge for community service. 
The home project. — It is agreed by teachers of agriculture that 
instruction in this subject should follow certain definite lines. 
1. It should be seasonal; that is, a monthly or seasonal sequence 
should be followed out as far as possible in the presentation of these 
lessons. 
2. It should be local in its interests and development. 
3. It should meet the interests of the pupils. 
4. It should be practical. 
The home project affords the best means for meeting these con- 
ditions, especially the practical condition.
