ILLUSTRATIONS 



Plate I. Crowded small pole stands of shortleaf pine about 30 

 years old in need of thinning. The trees are slender and clean 

 stemmed, but irregular in size. A large number of the smaller 

 trees should be removed Frontispiece. 



-Plate II. A dense sapling stand of shortleaf pine 15 to 18 years 

 old, but too small to be profitably thinned. While the clean 

 condition of the floor is good, fire could do great damage to 

 such a stand 



Plate III. Understocked large pole stand of shortleaf pine 30 

 years old. The trees are short-bodied and knotty and will yield 

 only low grade lumber. The best that can be done with such 

 a stand is to cut it, leaving the most slender, clean-bodied 

 trees for seed-trees 



Plate IV. Crowded, large pole stand of shortleaf pine 40 years 

 old, badly in need of thinning by removing the smaller pines 

 and many of the hardwoods. Condition of larger trees, with 

 long, smooth bodies, excellent 



Plate V. Mature stand of shortleaf pine. Trees nearly uniform in 

 size and ready to be cut for lumber. Groups of slender, wind- 

 firm trees can be left for seed trees, 



Plate VI. Figure 1. A typical case of sustained rapid diameter 

 growth, resulting from repeated thinnings, in a tree of short- 

 leaf pine which was overcrowded for many years. Wood of 

 such a tree is free from large knots, and its stumpage is 

 worth $8 a 1,000 board feet under a cost of operating of $12 



Figure 2. Stem of a small sprout sapling of shortleaf pine, 

 crooked and scarred at the neck as a result of the original 

 seedling having been killed to the ground by fire. Stump and 

 root rots gain entrance through such scars.
