212 NUT GROWING 



to have more than one variety, preferably several 

 varieties in any one orchard. 



One important function of the hazels will relate 

 to their value as fillers in orchard planting of nut 

 trees. If the black walnut, the Persian walnut, and 

 the pecan hickory, for example, are to be set one 

 hundred feet apart, a good many years will be re- 

 quired for the filling of unoccupied space. Orchard- 

 ists sometimes try to split the difference by setting 

 large kinds of trees fifty feet apart with the intention 

 of cutting out every other tree when the limbs touch. 

 Hazels as intercrop trees may be cut out one by one 

 as the space is required without much loss because of 

 their comparatively small size.
