48 BULLETIN 305, U. S. DEPAETMENT OP AGBICULTUEE. 



Geography: From what locations were the trees for the school 

 ground secured ? Did they grow on upland or lowland ? Do they 

 require much or little moisture ? 



Arithmetic: Develop problems on the cost of trees planted in the 

 school yard. 



ANIMALS. 



Continued work. — Continue the studies with the special bird group. 

 Note the coming and going of members of the group, their methods of 

 securing food, the places frequented, and whether they are found in 

 flocks or alone. 



Do' any members of the special group of mammals come out of 

 winter quarters this month? The woodchuck or groundhog? The 

 chipmunk or ground squirrel ? 



Assigned work. — Pupils in the extreme southern part of the country 

 should look for the citrus white fly. It is found on the plants of citrus 

 fruit, cape jessamine, and privet. The insect is in the pupa or dor- 

 mant stage. It is oval in shape, has a thin light-green case, and is 

 found under edges of bark. Have pupils secure specimens and bring 

 them to school for study and identification. Store some in a bottle 

 and note developments. 



By following turnplows this month white grubs, cutworms, and 

 beetles may be found. Pull loose bark away from stumps in fields and 

 collect insects found there. Study to identify them. Send those 

 that can not be identified to the State agricultural college, with, the 

 request that the name and the helpful or harmful characters be 

 furnished. (See Farmers' Bui. 606.) 



Have pupils examine seed Irish potatoes for scale and blight. The 

 blight is indicated by the presence of brown, sunken spots on the skin 

 extending into the flesh of the tuber. Affected seed should either be 

 discarded or treated with formalin solution before being planted. 



Practical work. — Take notes on observations with birds and mam- 

 mals and copy them in the class notebook. Collect, identify, mount, 

 and label insects as suggested in the foregoing studies. (See Farmers' 

 Bui. 606.) 



Correlations. — Language : Have all the members of the class write 

 letters to the State experiment station with reference to insects being 

 sent for identification. Select the best one and mail it. 



Drawing: Make drawings and label the insects studied this month. 



Reading: Have the class read selections from Farmers' Bui. 606. 



History and geography: What connection has the Baltimore oriole 

 with American history ? Who was Lord Baltimore ? Where did he 

 settle ? Why did he come to America ? What are the colors of the 

 oriole ? What were Lord Baltimore's colors ? Does this fact account 

 for the name of the bird ?
