336 ELEMENTS OF FARM PRACTICE 



Com. — In this rotation corn is planted on manured 

 pasture sod each year. This is a very desirable place for 

 corn, and usually results in good yields. 



Study the accompanying charts and, if possible, draw 

 them and put in the crop that would be grown on each field 

 each year. The figures 1, 2, 3, 4 and 5 indicate the 1st, 

 2nd, 3rd, 4th and 5th years of the rotation. Each crop is 

 produced each year. 



This five-year rotation is a good one for many farms, 

 and every farm boy ten years old and over should thoroughly 

 understand it and its advantages over no rotation. 



Such a rotation tends to keep the fields clean of weeds, 

 productive, and to economize labor. Each field is plowed 

 but twice in five years and seeded but three times in the 

 five years. Still it is kept in good condition for the crop 

 it is to grow, because the crops are so arranged that each 

 crop helps to fit the soil for the one that follows. 

 Questions: 



1. What is the five-year rotation described above? 



2. If one had five 20-acre fields cropped to the above 5-year 

 rotation, how many acres of grain would one raise each year? How 

 many acres of corn? Of pasture? 



3. In what ways does the five-year rotation described above aid 

 in cleaning the land of weeds? 



Arithmetic: 



1. If a farmer on the above 160-acre farm kept 15 cows, 8 two- 

 year-olds, 10 yearlings and 12 calves, how many head of cattle would 

 he have? 



2. If each cow required 1 acre of pasture for the summer, each 

 two-year-old % acre, and each yearling 3^ acre, how many acres of 

 pasture would be needed? 



3. If each cow required, during the winter, 2}4 tons of hay, 

 each two-year-old 2 tons, each yearling 1 ton, and each calf 34 of a 

 ton, how many tons of hay would be needed? 



4. If the 27 acres of rotation meadow produced two tons per 

 acre, and the 12 acres of permanent meadow produced 13^ tons per 

 acre, how many tons of hay would the farm produce? 



FARM ACCOUNTS 



Bookkeeping. — One of the first essentials of successful 

 farm management is a set of accounts that will show which 

 enterprises are paying and which are not. To keep a com- 

 plete set of books for all the enterprises on a farm requires 

 considerable time and training, but most any farmer or
