124 Lessons in Fruit Growing. 



ricli land, thoroughly prepared. The soil between the 

 trees may be planted with hoed crops (153). 



6. Pecan nuts are gathered as they fall; they should not 

 become wet; those of medium size and below are polished 

 before marketing (155). 



7. Three species of the chestnut are cultivated to some 

 extent in eastern United States; the native species is hardi- 

 est of the three, and produces the sweetest nuts, but the 

 two introduced species produce larger nuts (159). 



8. The chestnut thrives on high, sandy land, gravel 

 ridges or mountain slopes (161). The trees are grown from 

 seed, and improved varieties are perpetuated by ordinary 

 grafting methods (162). 



9. The soil of the chestnut orchard is preferably kept 

 well cultivated and moderately fertile (163). 



10. The English or Persian walnut is cultivated to some 

 extent in eastern United States, but principally in southern 

 California. The trees are productive in only a few locali- 

 ties (167). 



11. Trees of the English walnut are seldom grafted; the 

 largest, thinnest-shelled nuts from hardy and productive 

 trees are commonly planted (169). 



12. Trees of the English walnut are planted about 40 

 feet apart each way. The ground should be cultivated ; if 

 well fertilized, it may be planted with hoed crops, or the 

 smaller fruit trees (170). 



13. The nuts are gathered as they fall; if the hulls do 

 not open, they are removed by hand, or by light pounding. 

 The nuts must be dried before being stored in bulk (171). 



14. The almond is successful in the United States only 

 in a few districts in California, Utah and Arizona (174). 

 The tree resembles the peach tree in many respects (175).
