CORRELATING AGRICULTURE IN NORTHERN STATES. 15 
Pupils should be encouraged to use the scientific terms in many 
cases, in which event they should learn to spell them. Use common 
terms when accurate, however. 
Arithmetic. — Milk records, computing rations, butter-fat computa- 
tions, poultry cost and income problems will furnish much of the prac- 
tice needed. While judging corn, determine what increase per acre 
would result if one more average kernel per row would develop on 
each ear. From some of the records of insects and weed seeds eaten 
by the winter birds make up problems as to the possible saving to the 
farmer. Use also crop statistics in census report or the Yearbook of 
the Department of Agriculture, usually to be found in township or 
private libraries. Have pupils count the number of average ears in 
a bushel of corn raised in the district. Shell and weigh again. Have 
problems computed on this basis. Weigh 100 or 1,000 kernels and 
estimate number per bushel. Borrow scales or weigh at home. 
Geography. — Locate on the township map the industries in the 
township and county which may be related to farming, as the grist- 
mill, the sawmill, grain elevator, tobacco-sorting shops, broom shops, 
tannery, creameries, and cheese factories. Trace also the local and 
more distant markets for eggs, butter, milk, cream, fruit, and vege- 
tables. How many dealers between the farmer and the consumer. 
Look up the range of the birds which are winter residents. Make a 
list of important climatic records, such as dates of early snows, high- 
est summer temperature, lowest winter record, depth of freezing of 
the ground, etc. Compare with other parts of the State and the 
Nation, drawing conclusions as to how the local agriculture is 
affected. Make a district survey of dairy cattle, including number on 
each farm, breeds, pure bred or scrubs, silos, sanitation, records kept, 
testing for butter fat, and feeding methods for each farm. (See Sur- 
vey Form in Supplement VII.) Use both map and chart methods. 
Keep figures for arithmetic. 
History. — Write to a dairy association for information about the 
history of dairying for the State, the story of modern scientific dairy- 
ing, the Babcock test, the separator and clean milk. Trace the prodi- 
gal farming methods of the past and show how these must be modified 
in the near future. Find what great Americans have been reared on 
the farms. Show how the farmer must have great influence in the 
affairs of the Nation, also the necessity of his being well informed and 
broadly educated. Find the effect of seed selection and milk testing 
in sections which have tried them. 
Drawing. — Have careful drawings made of ideal ears and kernels 
of corn. Working drawings or sections should be prepared while the 
milk tester is being explained and used. Have pupils make a sec-
