In the past, uncontrolled clearcutting on many of the good to excellent hardwood sites in the Appalachians has resulted in forest stands composed of the so-called cove hardwoods, a high proportion of which are intolerant species. Characteristically these stands run heavily to yellow-poplar (Liriodendron tulipifera L.), northern red oak (Quercus rubra L.), black cherry (Prunus serotina Ehrh.), basswood (Tilia americana L. and T. heterophylla Vent.), white ash, (Fraxinus americana L.), and sugar maple (Acer saccharum Marsh.); and the first three species generally make up more than half the...

In a study at the Beltsville, Md., Experimental Forest in 1953 and 1954, the seed of Virginia pine (Pinus virginiana Mill.) became at least 45 percent viable 8 weeks before the natural opening of cones. Because seedfall in that locality usually starts during the first or second week of November, it was concluded that cone collecting could begin there safely in early September (1).

Sawmill operators generally recognize the problem of defects due to air-drying hardwood lumber, but they often fail to realize how much these seasoning losses cost in money, time, and wasted lumber.
