GROWTH. 



HEIGHT GROWTH OF SEEDLINGS. 



Table 10 shows averages of seedling height growth. This growth 

 is affected to such an extent by local conditions that tables not 

 based on a very large number of measurements, taken from all 

 qualities of locality, can not be closely compared. The parallel col- 

 umns will furnish a rough comparison and give some idea of devel- 

 opment. All of the measurements indicate that the growth for the 

 first six years is very slow.
