MAIN FOREST. 



Since writing the above, Mr. J. Cooper, Acting Conservator of Forests, Knysna, 

 has kindly procured at my request the following measurement of trees in the Main Forest 

 at Knysna, and I take the opportunity to add these to the foregoing. The Stinkwood 

 trees measured, and some of the others, were left standing in a clearing made along the 

 Main Forest road, and received thus more sunlight than those situated in the adjoining 

 forest ; hence the rates of growth are in general greater than those for the Gouna forest, 

 and approximate more closely to those that would be obtained in plantations :
