10 BULLETIN 132, U. S. DEPARTMENT OF AGRICULTURE. 
advanced pupils problems involving the following items of farm management should 
be developed and assigned: Harvesting, preparing for market, the cost of marketing, 
the cost of feeding poultry flocks, the cost of feeding dairy cows, the value of their 
products, and the per cent profit or loss. 
EXCURSIONS AXD PRACTICAL WORK. 
Excursions should be made with a view of making comparison of old and out-of- 
date and new farm machinery, gins, grain mills, etc. 
During the month of December indoor exercises in studying and learning to iden- 
tify seeds of plants and weeds, and learning to distinguish between good and bad 
seeds should be practised. 
JANUARY. 
LANGUAGE LESSONS. 
Conversations concerning the uses of fertilizers, the quantity required, and for 
what crops, should be engaged in with the younger pupils. Oral and written accounts 
of visits to fertilizer plants, methods for distributing fertilizers, and methods of 
mixing should be required of the more advanced pupils of the group. Descriptions 
of fertilizer distributors, fertilizer mixing boxes, and the different brands of fertilizers 
should constitute work for the still more advanced pupils of this group. 
READING AND SPELLING. 
The following selections are suggested as supplementary work for this month: 
Winter Time, K. L. Stevenson; The Snowdrop, Tennyson; The Frost Spirit, Whit- 
tier; and Snowbound, Whittier. 
List and assign words found in the correlation exercises of this month adapted to 
the use of the several classes. Among this number should be found such as follows: 
Sacks, brand, potash, acid, nitrogen, mixed, material, fertilizer, community, distrib- 
utor, commercial, elements, manufacture, formula, problem, profit. 
DRAWING. 
The drawing work of the month should consist of outlines of fertilizer sacks, ferti- 
lizer horns, fertilizer mixing boxes, tools employed in home mixing of fertilizer, and 
sketches of more improved fertilizer distributors. 
Study the history of the use of commercial fertilizers in the community and county, 
noting the principal brands and formulas that have been used and in connection 
with what crops. Let special attention be given to the effect that the use of fertilizers 
has had upon the agricultural development of the community, noting the crops grown 
previous to the use of fertilizers and those grown since their use. Also study the 
effect of fertilizers on the yield of crops. The development of the industry of manu- 
facturing fertilizers in the community, county, and State should be studied, and in 
connection with this the history of the prices and the conditions that have affected 
prices. 
GEOGRAPHY. 
Study the leguminous crops that can be grown in the community successfully, 
noting the locality and the conditions obtaining. Extend this study to the county, 
noting where the leguminous crops are grown and not grown and the reason. Locate 
the fertilizer plants in the community, county, and State, and assign reasons for 
the particular location. What and where are the raw fertilizer materials found in the 
community, county, and State? What crops are exchanged for fertilizers, and is the 
exchange made at a profit or loss?
