will be given in a subsequent chapter, where the 

 special methods of grafting and budding will be 

 more fully examined. It suffices for the moment 

 to emphasize the fact that these methods of 

 propagation are as advantageous in the case of 

 the walnuts, whether hybrid or of pure strains, as 

 in the more familiar case of fruit trees. 



Of course the stocks on which to graft must be 

 grown from nuts, and I have already pointed out 

 that the seedlings are likely to show diversity. 

 But all that is necessary is to plant the seeds 

 rather thickly, and then to save the seedlings that 

 show the best qualities. 



Starting a Walnut Orchard 



A practical method of producing a permanent 

 and profitable orchard with a foundation to last 

 for a century, is to plant some seeds of the Royal 

 hybrid in groups of three or four at intervals of 

 fifty feet each way. By the end of the first season 

 the strong growers will have asserted themselves, 

 and the others can be weeded out. There will 

 almost surely be at least one good tree in the 

 group. Failing that, there will be other groups 

 in which there are extra seedlings of good quality 

 that may be transplanted. 



The seedlings should be allowed to grow for 

 four or five years, the ground about them being 

 cultivated and may be used for crops of corn,
