The boy or girl who has noted these facts about woodland, soil, and stream

 The examples of soil protection and clear streams, of erosion and flood damage that 

 he or she finds in his own neighborhood, are intimations of the larger meaning

Location and Extent of Farm Woodlands 



Aim. — ^To learn how to determine the location and area of land on the farm 

 on which trees should be grown as a crop. 



Sources of information. — Farmers' Bulletins 1117 and 1940; Leaflet 29. 



Guides to study. — Timber is a poor-land crop. Observe places about the farm 

 which should be kept in forest trees and woods. Places where forest trees are 

 profitable: (1) Poor soils. (2) Steep slopes. (3) Eroding soils. (4) Rocky land. 

 (5) Wet land. (8) Unused corners or waste places.

Figure 19. — Rough, steep, and poor lands, and inaccessible parts of the farm may be used to increase 

 farm income by growing trees in permanent woodlands. 



Extent of woodlands in the locality: Proportion of cropland and woodland. 

 The total acres of woods on 10 to 20 representative farms in a locality. 



Practical things to do. — From the data gathered in the survey construct a chart 

 showing the proportion of cropland and woodland, the total crop acreage, and the
