l/nder the (inmp System openings are made here 

 and there in the forest by cutting away rip* 1 trees. As 

 the reproduction proceeds, the old trees about the 

 openings are gradually cut away, and the groups of 

 young growth, spreading from the original openings 

 like drops of oil on water, finally meet.

This is one of the simplest and most useful of all the 

 system-, and when the openings are made small at first 



no other is so safe. It is especially adapted to small 

 pieces of forest, such as woodlots. because it is simple, 

 and beeau-e it a>sures the safety of the forest even with 

 very little skill or care on the part of the owner.
