Summarizing the data in above table by height classes termed poor, 

 average, and very good in quality, the following table is presented : 



Table 4. — Percentage White-pine Transplants According to Quality, Height, and 



Origin 



An interesting fact ascertained from column 5, Table 3, is that 10 

 per cent of the trees are inferior for forest planting when the spacing 

 in the transplant row is so close as i^/^ inches and the transplants are 

 kept two years in the nursery. For producing four-year transplants a 

 wider spacing seems necessary. Careful experiments along such lines 

 as these are desirable.
