CORRELATING AGRICULTURE IN SOUTHERN STATES. 11 



ARITHMETIC. 



Have the younger pupils count the number of sacks of fertilizer used at home and 

 report this to the teacher. Let the total number of sacks be determined, the total 

 number of pounds for each farm, for the community, and find the average number 

 of pounds used per acre for each farm and for the entire community. Multiply this 

 work to include the cost per acre, per farm, and for the community. For the more 

 advanced pupils develop simple problems on the cost of fertilizing elements taken 

 from the soil by each crop. Prepare statements of problems involving the replacing 

 of fertilizing elements by leguminous and other cover crops and by the use of mold. 

 Problems involving the cost of the elements in various fertilizers as determined by 

 their formulas should be developed. 



EXCURSIONS AND PRACTICAL WORK. 



Visits to fertilizer plants, warehouses, etc., for the purpose of observing the mixing 

 processes and of securing the names of the different brands, their formulas, and special 

 uses, should be made. The necessary data for the other correlation exercises should 

 be secured on these trips. 



Dining this month the school grounds should be laid out and the year's work 

 planned. The plats of the individual pupils in the school and home gardens should 

 be laid out and located during this month. Making stakes and other devices to be

used in the school and home gardens should constitute some of the practical work 

 of the month. 



FEBRUARY. 



LANGUAGE LESSONS. 



Conversations on the need, value, and methods of seed testing should be engaged 

 in. For the slightly more advanced pupils oral and written narrations of the steps 

 in making a seed-testing box should be required. Written descriptions of seed-testing 

 boxes should be assigned as work for the still more advanced pupils. Conversations 

 and oral and written statements concerning the value of sprays, the materials used, 

 the steps in mixing, and the devices used, should be given. Descriptions of methods 

 of pruning and grafting should constitute work for the advanced pupils of this group.
