72 FIRST BOOK OF FORESTRY 



Carolina and Virginia are covered with pine. In this 

 case the pine is a line tree, called l^y the people of those 

 districts shortleaf pine, and on account of its disposition 

 to cover old fields it is also called old-field pine. It is 

 cut in large quantities for saw-logs, and it is not an 

 unusual sight to see men log this pine on land where the 

 old corn rows are still visible. Evidently the seed from 

 which these pine trees sprang came from the neigliboring 

 forest and was blown across the fields. Being so success- 

 ful in many cases, this way of reproducing the forest has 

 been used by the forester, and since the seed comes from the 

 neighboring forests, the ground is seeded from the side and 

 not under the seed trees, as in the method described before. 

 In using this method it is customary to fell all trees on 

 a strip fifty to seventy-five yards wide, or about twice as 

 wide as the trees are high, and then to wait until the 

 strip is fairly covered with young seedling growth ; then 

 to cut another strip, widening the original strip by another 

 seventy-five yards, and so on, until the entire piece is cut 

 over. Of course any young growth is saved as much as 

 possible in cutting the timber, and in valuable forests any 

 places which are not covered within a reasonable time, 

 say three to six years, are filled by planting. Since the 

 seed is carried by the wind, it is well to extend the strips 

 north and south, and Ijegin on any particular piece along 

 the east line, so that the prevailing westerly winds will 

 carry the seed over the strip.
