TIMBER PINES OF THE SOUTHERN UNITED STATES. 

 Tablk Il.—Groiilh of Loblolly Pine (I'iiius taila) from fiftij to one hundred and fiftij-six yean. 



From Table III aud tlie correspondiug diagram, based upon a considerable number of trees, it 

 appears tbat the Loblolly Pine is nearly -10 feet high when twenty years old ; that the length of the 

 merchantable timber (00 feet) is attained at the age of forty; that this shaft has a basal diameter 

 6t' 20 inches at the age of one hundred years, and that the age of thrifty growth is practically at 

 an end when the tree is one hundred and ten years old. Comparing th's table with those for 

 Longleaf and Shortleaf pines, the excellence of the Loblolly becomes apparent.
