90 PRACTICAL FORESTRY IN 



to hardwoods. Those species, however, whose seeds are in the 

 form of nuts, such as hickories, black walnut, chestnuts, and 

 oaks, are particularly adapted to propagation by direct seed- 

 ing. Other species, such as ash, tulip, poplar, and black 

 cherry, whose seeds are small, are better grown, for one year 

 in nurseries before transplanting into the field. Where plan- 

 tations are started by planting the nuts directly in the field, 

 the cost will be moderate. The nuts can be obtained in any 

 quantity from eastern seed dealers, and their cost, together 

 with the labor of planting them, should not exceed $4 per 

 acre. Where the area planted is level and free from under- 

 brush, preliminary plowing and harrowing, while adding 

 $1.50 to $2 to the cost per acre, will add much to the suc- 

 cess of the plantation. Cultivation during the early years of 

 the life of the trees will also result in increased growth.
