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 Phmfing. — It is obvious from the above that plants should 

 not be left too long in the nursery before planting out.
