None of the plantations except 30 and 



35 shows a sufficient profit 



at its present age to encourage the plant 



ing of walnut as a commer- 



cial investment. The tree has a long life 



>, and requires a longer time 



for the heartwood to develop than man} 



r other species. A properly 



cared-for and well-grown walnut plantati 



on would undoubtedly show 8 



considerable profit when 50 years old, an 



d the profit would probably [ 



be greater at 100 years. Such a long-ti 



me investment, however, is f
