half the contents of a fully stocked stand at maturity. If the latter, 

 for example, is 40 cords per acre, then the woods should never con- 

 tain less than about 20 cords per acre as the growing stock or basis 

 necessary to secure the maximum production. This does not apply 

 to mixed hardwoods cut clean and renewed by sprouting. 



Effect of the general rise in the value of all timber products in its 

 relation to desirability of holding woodlands and keeping them pro- 

 ductive. How a forest tract may supply timber yearly for many 

 years and meanwhile increase in value and be worth more at the end 

 of a long period. 



Growing timber as a bank account upon which the owners may draw 

 repeatedly without diminishing the capital. A good form of prop- 

 erty to be handed down to the children as an inheritance. 



Fio. 19.— Rough, steep, and poor lands and inaccessible parts of the farm increasing farm income 

 by growing trees in permanent woodlands 



Keeping fire out of the woods, cutting the trees carefully, and find- 

 ing the best markets for excess timber products not needed on the 

 farm are indications of sound judgment in farm management. 



Practical exercises. — A survey of the methods of caring for the 

 farm forest should be made. This survey should inquire into the 

 general practice of the district in the care of the forest, the forest 

 products marketed, the utilization of waste or idle lands for forest 

 tracts, the practice of replanting forest plats, and the general relation 

 of the acreage in forest to the crop and pasture acreage. From 

 this survey many facts will be obtained for class discussion in forest 

 management. A field trip into some of the farm woodlands of the 

 district is desirable where the studies made first-hand should include 

 the farm practice on the care of the forest.
