A selection felling has resulted in an open stand, because the ground (grass covered) was not worked to assist regeneration. left were preferably on rocky ground and very steep slopes. The cutting in one locaUty where conservatism was indicated by the steep slopes removed, in a Ught selection system, about 20 per cent of the stand. An experiment was being tried out by cutting in strips running hori- zontally aroimd the slopes. The strips cut were about 100 feet in width.
