It is interesting to note that the results obtained from tlie 

 small number of trees considered under each species, are borne 

 cut by an inspection of the forests of the region studied. The 

 relative height of the species is, without doubt, practically cor- 

 rect, and while the average height of each species might require 

 some modification, it is approximately correct. Within each species, 

 however, the tables show that in trees of the same diameter the 

 height may vary widely. In the case of the black walnut, for ex- 

 ample, tree No. 179, with a diameter of fourteen inches, is forty 

 feet high, while tree No. 163, with a diameter of thirteen inches is 

 eighty-six feet high. It is, however, safe to say that any con- 

 siderable number of Black Walnut trees of a diameter of thirteen 

 to fourteen inches will average about sixty-five feet in height. 

 This wide variation in height is, in the region under oonsi dera- 

 tion, due in some measure to the unevenness in density of the 

 second growth stand. In some cases the conditions are practically 

 those of the open, while in others they are forestal. 



Another feature brought out by the tables is the scant amount 

 of clear bole, which in some cases is as low as six feet and in many 

 does not exceed eight or ten feet. An examination of the datum 

 sheets shows that this is directly related to the density of the 

 stand. In case of a short clear bole there are no other trees within 

 a radius of fifty feet, or if any are present they are so small as to 

 show that they have sprung up after the tree m question had ac- 

 quired its permanent form.
