None of the plantations except 30 and 35 shows a sufficient profit 

 at its present age to encourage the planting of walnut as a commer- 

 cial investment. The tree has a long life, and requires a longer time 

 for the heart wood to develop than many other species. A properly 

 cared-for and well-grown walnut plantation would undoubtedly show 

 considerable profit when 50 years old, and the profit would probably 

 be greater at 100 years. Such a long-time investment, however, is 

 seldom considered desirable.
