54 ON THE TIMBER LANDS TRAVERSED BY A 
From the foregoing tables, taken from different parts of the 
forests throughout the entire length of the State, and, there- 
fore, as general as it is possible to obtain them, much informa- 
tion can be obtained as to the effect of height above drainage 
on Kentucky timbers. For instance, let us take white oak 
and go through the various tables. The following is the re- 
sult :

From this table can readily be deduced the average height 
of all the hills in Kentucky selected for these experiments, 
the average height above drainage to which white oak grows, 
and the relation that the latter height bears to the entire 
height of the hill. The following table shows these deduc- 
tions :

In other words, throughout the forests of Kentucky the white 
oak extends, on a general average, over sixty per cent. of the
