CROMWELL] AGRICULTURE FOR RURAL SCHOOLS 69 



A Course of Study for the North Central States. 



SEASONAL sequence. 



September and October. — Seed selection, especially seed 

 corn; birds; insects; weeds; the plant and how it grows; plant 

 breeding, especially potato. 



November and December. — Housing farm crops and animals ; 

 feeds and feeding; stock judging; scoring corn, fruit, domestic 

 science products, and potatoes. 



January and February. — Care of farm animals ; ventilation ; 

 dairying; farm acounts ; farm machinery; seed testing; repair of 

 farm equipment. 



March and April. — Field management; crop rotation; poul- 

 try ; care of vegetables and eggs ; landscaping ; gardening ; weeds ; 

 fruit growing; flies and mosquitoes. 



It will be noticed that by the above course, we study gathering 

 seed corn when that is the dominant home interest, and then we 

 learn to score corn at the time when the farmers are trying to 

 pick corn for the various corn shows. Again we study weeds 

 in both fall and spring for there is something to do in both fall 

 and spring in order to keep down weeds. Birds may well have a 

 place in our course both fall and spring. If we are to improve 

 our potato seed, we must pick potatoes from those hills that have 

 five or more good sized and good shaped potatoes in them. Hence 

 plant breeding, especially potato breeding, must come in the fall. 



- The Small Crustaceans 



first paper. 

 W. C. Allee. 

 The crustaceans are to the water of our small lakes and ponds 

 what the insects are to the air. The two groups are closely related, 

 both belonging to the phylum Arthropoda; that is, to the group 

 of animals that have a hard external covering, usually divided 

 into easily apparent segments, and that have jointed appendages. 

 The crustaceans may be distinguished from the insects because 

 they have two pairs of antennae in front of the mouth while the 

 insects have but one pair. These differences may be readily seen 

 by examining an ordinary crayfish, which is the best known and 

 largest of our fresh water crustaceans, and comparing the anten- 

 nae with those of a grasshopper. This paper deals with certain 

 facts concerning the small crustaceans (crayfish excluded) that 

 may be of use to the amateur collector.
