It is believed that implements patterned somewhat after the better of the European forest plows of the wheel and roller types could be advantageously introduced into the United States. Artificial regeneration on heaths is always very difficult, due to the mineral soil being too poor to support satisfactory growth. The organic matter overlying the mineral soil contains humic acid and other sour humous constituents deleterious to tree growth. The difficulty is often increased by the presence of pan at shallow depths. Greve1 recommends the burning of the surface as the first operation, care being taken to injure the organic matter in the surface soil as little as possible. The surface layer of organic matter is then thoroughly mixed with the mineral soil beneath. It is usually useless to attempt artificial regeneration on heaths without previous soil preparation. 17.
