ELEMENTS OF FARM PRACTICE 



Arithmetic: 



1. If it costs $1.25 to plow an acre of land, 50c. to harrow it 3 

 times, 25c. to plant it, $1.60 to cultivate it 4 times, and 60e. to manure 

 it, 25c. for seed, and $3.00 for rent, how much does it cost to raise an 

 acre of corn? 



2. If it costs $7.50 to raise an acre of corn, and $2.00 annually 

 to fence it, how much does it cost per acre? How much does the corn 

 cost per bushel, if it yields 40 bushels per acre? 



3. If it requires 8 lbs. of ear corn to make one pound of pork, 

 how many pounds of pork will 40 bus. of ear corn make? (72 lbs. per 

 bu.) How much will the pork made from 40 bus. of corn be worth at 

 5c. per lb.? 



FEEDING SOWS AND FIGS 



Feeding the Brood Sow. — It is very easy to overfeed 

 a brood sow in winter. If she has raised two litters of pigs 



during the year, so she is likely 

 to be thin in the fall, she will 

 need considerable feed until 

 she begins to fatten up a lit- 

 tle. If she has raised but one 

 litter, which is the practice on 

 most farms, she will have had 

 the whole fall to fatten up, 

 and very little grain is neces- 

 sary or desirable during the 

 winter. 



Bulky Feed. — If only one 

 or two sows are-kept, the slops 

 from the house furnish an ex- 

 cellent form of bulky feed, 

 which helps to satisfy their 

 appetites, but really contains 

 little nutriment. If a large 

 number of sows are kept, the 

 slops from the house do not 

 go very far, and one is likely 

 to feed them more grain, to 

 keep them from squealing, 

 than they really need. If 

 supplied with good clover hay, 

 hogs will soon learn to eat it; 

 and this furnishes the bulk

 and cheapest summer feed for pigs.
