From Table III and the corresponding diagram, based upon a considerable number of trees, it 

 appears that the Loblolly Pine is nearly 40 feet high when twenty years old ; that the length of the 

 merchantable timber (60 feet) is attained at the age of forty; that this shaft has a basal diameter 

 of 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 this table with those for 

 Longleaf and Short-leaf pines, the excellence of the Loblolly becomes apparent.
