CHOICE OF SPECIES IN ARTIFICIAL REGENERATION 51 



posts should favor the planting of catalpa because of its rapid 

 juvenile growth and the durability of the wood. In the vicinity 

 of towns and cities, where there is a large demand for wood for 

 fuel, species can be profitably grown that would be out of place 

 in inaccessible regions because of the cost of transportation. The 

 question of economic utilization is an important one in its bear- 

 ing upon the choice of species. Species seeded or planted in the 

 vicinity of a good market or accessible to it at little cost for 

 transportation should be such as permit of complete utilization. 

 The cost of management, the value of the thinnings, and the re- 

 sistance to decay may be cited as additional factors which may 

 determine the choice of species.
