CHAPTER XVIII 
A CHAPTER OF DON’T FORGETS 
ON’T FORGET — That soil is as jealous as 
1) a lover; neglect or mistreat it and its bounty 
is withdrawn. Caress and feed it, it yields a 
hundredfold. 
Don’t Forcet — That a farmer becomes a soil robber 
when he does not each year put back into the soil more 
organic matter than he farmed out of it. 
Don’r Forcet— That the corn stalk is one of the 
farmer’s best by-products. A ton of them contains six- 
teen pounds of nitrogen and nearly as many pounds of 
potash, and the organic matter in them is of inestimable 
value for supplying humus to the soil. 
Don’r Forcer— That the moisture-conserving ca- 
pacity of the soil is increased by the plowing under of 
large amounts of organic matter. 
Don’t Forcet — That organic matter in the soil aids 
soil ventilation, and furnishes supplies of nitrogen for 
the growing plant. 
Don’t Forcet — That rye, hungarian and the legumes 
are the best producers of organic matter. 
Don’r Forcet — That the farmer who refuses to sup- 
ply the wants of his soil is traveling along the highway 
of the abandoned farm.
