FOREST PLANTING IN THE LAKE STATES 
49 
The height growths for the different species and conditions indi- 
cated by the wide bars in Figure 6 are made up from the averages of 
the individual plantations of which those above the general average 
are indicated on the narrow bars. A glance at them shows that there

is wide variation in the height growth of different plantations of 
the same species growing under similar conditions. The maximum 
height to the nearest foot of any one plantation for each condition of 
site and competition is shown in Table 6. The poorest growth is
