work has been carried on more extensively in the 
South than elsewhere, largely in the naval-stores 
industry. 
FARM FORESTRY 
In carrying on an educational program as applied 
to farm forestry the Forest Service works in co- 
operation with the Extension Service of the United 
States Department of Agriculture. This work is 
focused particularly on the more efficient management 
of farm woodlands, the reforestation of those farm 
lands not now suitable for agricultural crops, and the 
marketing and utilization of farm timber. A consid- 
erable number of agricultural colleges give courses on 
these subjects, and an increasing number are includ- 
ing similar work in their extension programs. For- 
estry extension specialists are appointed as members 
of the college extension staff. They work with the 
county agricultural agents and the farmers in much 
the same way as do the extension specialists in other 
lines of agriculture. The object of their efforts is to 
demonstrate to farmers that the growing of trees and 
the efficient utilizatiton of forest products is a desir- 
able part of their plan of farm management. When 
it is considered that about 150,000,000 acres, or about. 
one-third of the forest land of the country, is in farm’ 
woodlands, the importance of this work is realized.

RESEARCH 
Comparable in importance with the administration: 
of the national forests are the many investigative 
activities in the field, laboratory, and office that are — 
erouped under the heading of forest research. These 
investigations cover a wide range of subjects, includ- 
ing the growth, management, and protection of the 
forests, the management of livestock range within 
forest areas, and the conservative and effective utili- 
zation of forest products, as well as the economic fea- 
tures of forest ownership, production of lumber and
