Abstract

Grade I South African Pine timber is not equal to the best imported softwood timber: The object of this investigation is to determine whether South African timber superior to the present Grade I South African Pine can be produced economically. As the above may indicate a rotational age differing from that advocated by Dr. I. J. Craib it is discussed and accepted that the size of logs required and for the highest rate of interest earned on the investment determines the rotational age.
