In the far South, special attention should be given to the ripening 

 citrus fruit. Here is abundant material for a month's work comparing 

 oranges, lemons, kumquats, and grapefruit. 



Practical work. — Providing apples, bark, leaves, cones, and making 

 observations called for in the foregoing exercises and keeping records 

 in the notebooks furnish practical work. 



Look after a school or home garden plat. Care for the crops and 

 keep vacant ground in good condition for early spring crops. 



Correlations. — Writing records and descriptions of the plants sug- 

 gested for study provide language exercises. 



Drawing: Outline a pine tree, a cone, a scale, a seed, a bundle of 

 needles, a single needle. 



Geography: Have pupils prepare a statement as to the locations 

 of the different cone-bearing plants in the community. Where do 

 the different kinds of pine grow — long-leaf, short-leaf, loblolly? 

 Where do the cedars grow ? Spruce, if any ? Peculiarities of the 

 various locations should be noted. 



History: Have members of the class write statements giving the 

 history of the pine-timber industry in the community for the past 10 

 years. 



Arithmetic: Use the rule given on page 10 to find the number of 

 board feet in logs of various dimensions suggested by pupils. 



Continued work. — Learn the names of the new birds that come to 

 the community this month. Do any of them belong to the particular 

 group selected for study during the year? Continue the studies 

 with this group. For suggestions see September exercise. (For lists 

 of groups and individuals of each see Appendix.) 



These additional facts with reference to the individual members of 

 the group should be noted :. 



(1) Appearance — alert, pensive. 



(2) Disposition — social, solitary, wary, unsuspicious. 



(3) Flight — slow, rapid, direct, undulating, soaring, sailing, flapping. 



The studies with the particular group of wild mammals is con- 

 tinued. Follow the suggestions in the September exercise. 



Which members of the group go into winter quarters? If the 

 squirrel group is being studied, compare the methods of hibernating 

 of the chipmunk or ground squirrel and the woodchuck or ground hog. 



Both usually five in the ground and both bore two or more openings 

 to their burrows — one stores up food in its burrow to eat during the 

 winter, and the other gets fat and goes to sleep. 



Assigned work. — No insect is of greater economic importance to 

 the southern farmers than the boll weevil. In a very short time it
