106 TIMBER PINES OF THE SOUTHERN UNITED STATES. 



TAIII.K ll.lirotrth of Shortleaf Vine during stage of rigorout growth, from fifty to one hundred and twenty yeart. 



TABLE III. Growth of Shortleaf Pine during stage of slow growth, latest stage of life. 



From the general table (No. IV) and the corresponding diagram it seems that in the average 

 the tree at twenty is about 30 feet high, reaches 50 feet at the age of forty, and that its growth in 

 height is in the main finished at the early age of 70. In keeping with this, the growth in 

 diameter is quite rapid during the first fifty years, continues at a moderate pace up to 80, when 

 the age of slow growth is entered.
