Notes on Above. 
Close Planting .— Although the trees are healthy and increasing in 
size yearly, the effect of close planting will be seen in the continually 
diminishing proportionate girths when compared with those in the 
open planting experiment, planted in the same year. 
Open Planting— It is obvious from the above that plants should 
not be left too long in the nursery before planting out.
