BULLETIN 464, U. S. DEPARTMENT OF AGRICULTURE. 
Material and exercises. — Select pictures and plans of houses from 
reliable sources. Have pupils inspect some good houses and make 
a class excursion for this purpose where it is feasible. 
Correlations. — Descriptions of buildings and equipment or the story 
of making the house will provide good language work. Plans, per- 
spectives, and working drawings are practical work. Problems in 
areas, lumber bills, and inventories should be drawn from the projects 
of the pupils. 
Manual training should include making nests and feed hoppers. 
Models of good styles of houses may be made, especially the model 
of the State college type. Such a model developed in the United 
States Department of Agriculture is illustrated in figure 6. This 
type of house has been made and used under the direction of the 
Poultry Division of the Bureau of Animal Industry. It has been 
found satisfactory on the Government farm at Beltsville, Md. A 
model of a selected type may be made by the pupils. 
LESSON FOUR. 
SUBJECT: POULTRY FEEDING. 
NOVEMBER. 
Topics for study. — Elementary principles of feeding. Available 
nutrition in different material used for poultry foods. Requirements 
for growth, renewal of tissues (especially feathers), warmth and egg 
production. Balancing a ration. Substitutions to save expense. 
Sources of animal food. 
The necessity of animal food is plainly shown in figure 7, in which 
the production of eggs is seen to be much greater in pens fed on either 
beef scrap, fish scrap, or skim milk than in the check pen where the 
ration contained no animal food. 1 
The rations used in obtaining these results over a period of four 
years were as given below: 
Rations to test the effect of animal food for poultry.
