A limit will by all means be advisable for each species, based upon a study of its rate of growth and the proportion which different diameters bear to its contents in board feet. It will be frequently necessary, however, to leave trees of a merchantable diameter where their removal would seriously impair the density or where seed trees are necessary. In the leaving of seed trees many considerations are involved, only a few of which can be mentioned here. ti(?nofiUeed8t?ceeCs:The 0aks> Hickories, Walnuts, and Chestnut should be favored, since their seed is too heavy to be carried by the wind, and much of it is eaten by animals. The marked tendency of the pines (see PI. LV), Hemlock, and Yellow Poplar to reproduce by groups must be encouraged. On south slopes and in dry localities generally, where Dogwood, Sourwood, and Scrub Oak contend with the timber trees, great care must be taken not to disturb the balance between them. The rich, moist soil of the Poplar coves is particularly likely to produce a luxuriant growth of weeds and brambles instead of tree seedlings if too much light is admitted to the soil, while the Ash, Cherry, and Basswood, which are only sparsely represented in the mature stand and are further handicapped among the young growth by their strong demands upon the light, will require an exceedingly conservative method of management.
