Fig. 2 shows a stand with an original planting distance of 5 to 6 varas between trees. The kikuyu grass is excellent under this stand but the spacing seems a bit close for the best growth of the alder. Apparently, there is some dif- sary in the wider spaced plantings to as- sure the production of clear lumber. Ob- servations of recently pruned stands indi- cate a tendency towards excessive pruning. Growth of the alder must be considerably retarded by removing such a high per- centage of the crown and it would proba- bly be better economics to prune oftener.
