Abstract The average farmer is not likely to be able to avail himself of the advice of a forester in handling his woodlands. It is therefore important to place at his disposal such suggestions as will enable him to do a more satisfactory job of management than would otherwise be possible. Two rules of thumb are suggested by the author to help him in controlling his growing stock both as to quantity and distribution of size classes. These are that (1) the spacing between trees, in feet, should be approximately the average d.b.h. in inches, plus 6; and (2) an average of one tree per acre per year should be harvested in addition to the trees removed by the D plus 6 rule. Illustrations are presented to show that these rules will exercise reasonably satisfactory control over the rotation and growing stock and at the same time keep the stand in good silvicultural condition.
