TIMBER GROWING AND LOGGING PRACTICE 5 
The Forest Service earnestly asks the forest landowners of the 
United States to determine for themselves, with the same care with 
which they would approach any other business problem, whether tim- 
ber growing does not offer a commercial opportunity which should 
be grasped. It commends this series of publications to the'm, not as 
a complete or authoritative scheme that can forthwith be followed 
with profit in their own woods, but as a starting point in utilizing 
the opportunities that forestry may hold out.

THE REGION AND ITS POSSIBILITIES 1 
The Central hardwood region includes about 40,000,000 acres of 
woodland in Ohio, Indiana, Illinois, Iowa, and Missouri, the southern 
portions of Michigan, Wisconsin, and Minnesota, the eastern edge of 
Nebraska and Kansas, the northeastern corner of Oklahoma, northern 
Arkansas, and the western half of Kentucky and Tennessee. (Fig.l.) 
As a forest region it differs greatly from other forest regions in the 
United States, in that three-fourths of the timber-producing acreage 
is in the form of farm wood lots, generally 10 to 40 acres in extent ;
