202 NUT GROWING 



every garden. When the market demands the nuts 

 in carload lots these garden trees will then furnish 

 scions for grafting upon wild walnut trees of other 

 kinds. This tree along with the black walnut would 

 appear to be particularly desirable for experimental 

 planting in prairie lands of the west that have been 

 worn out so far as grain crops are concerned. All 

 of our nut trees belong in the same category for 

 that matter, but the heartnut would seem to grow 

 almost anywhere excepting in the far south and the 

 far north. Trees of this species are smaller than 

 the black walnut and are believed to be not so long 

 lived. The early bearing would be suggestive of a 

 shorter life, but we do not as yet know if this means 

 fifty years or one hundred years for the full ma- 

 turity of the tree. Two Japanese walnuts in good 

 ground on my country property at Stamford were 

 about thirty feet in height at eleven years of age, but 

 others growing in glacial till were less than fifteen 

 feet in height at the same age. For orchard purposes 

 in good ground heartnuts may probably be set sixty 

 feet apart to advantage.
