APPENDIX V. 



MEASUREMENTS OF THE RATE OF GROWTH OF INDIGENOUS TREES. 



The following measurements were taken between 1882 and 1889 at the Knysna, on 

 trees in the natural forest ; the growth would probably have been more rapid had it been 

 aided by thinnings, and there is little doubt that the rates of growth observed would be 

 exceeded in plantations.
