CORRELATING AGRICULTURE IN NORTHERN STATES. 11 
Refer to such texts as Hunt's " Cereals in America." Have pupils 
make an outline map of the county and locate thereon the chief 
crops either by sketches or by grains, etc., glued on the map. This 
map will be useful in teaching younger pupils. Have a large map 
of the district made to be duplicated for future surveys. (See 
Supplement VII.) 
History. — Have pupils inquire into the history of grain and fruit 
development in this country, especially the crops now grown hi club 
work. Note the effect of the crops and the methods of raising 
them on the history of this country and the great national issues. 
As examples, notice cotton and tobacco in the South, grain and 
meat in Central States, dairying and diversified farming in New 
England. Trace the effect of the growth of cities on the type of 
agriculture in different sections, especially in supplying milk, garden 
truck, etc. Show how the free grant of rich lands led to careless 
farming because it was supposed their fertility was inexhaustible. 
Trace the growth of the work of the National Government and the 
State Government in encouraging good farming and in controlling 
pests and diseases. It is not to be expected that one class will 
develop all these topics. Select those adapted to the section and 
to the available reference books. Review the history of the develop- 
ment of harvesting machinery in the United States. 
Drawing. — Make cover design for booklets. (See Supplement 
VIII). Make other drawings or sketches needed to complete the 
booklets. Use fruit, grain, and vegetables for studies in sketching, 
color work, and designing. Have working drawings made for new 
poultry house and equipment, for improved shipping and storage 
apparatus. Make specifications and bill of lumber for each from 
these drawings in arithmetic class work. 
Physiology. — Take up poultry and eggs as human food. See 
Farmers' Buls. 128, Eggs and Their Uses as Food, and 182, Poultry as 
Food. Consider the feeding value and digestibility for farm animals 
of the crops harvested and stored from the club acre. Apply the 
lessons used in human physiology concerning foods and digestion. 
See Farmers' Buls. 22, The Feeding of Farm Animals, and 142,-The 
Nutritive Value of Food. 
Manual training. — Construct a model poultry house on a small 
scale. Have as many pupils as possible plan to construct poultry 
houses for their club flocks. Make full-sized nests and feed boxes. 
(See Farmers' Bui. 638.) Have the girls learn to cook and serve 
vegetables and fruits, also to can them and to preserve them in other 
ways. (See Farmers' Buls. 359 and 607.) Have them prepare and 
serve a variety of dishes from some of the produce of the projects 
and show these dishes at the exhibit. Have the mechanical work on 
the booklet done with care.
