THE WALNUT 



cultivation in any locality, hot or cold, moist or dry, 

 and is Ihe easiest to get results in grafting. This 

 species is very prolific, hence any variety of the Per- 

 sian nut grafted into it readily responds with boun- 

 teous crops; the nuts being larger and richer in oil 

 and flavor than when grown on their native root. 



On several occasions we made a test of the num- 

 ber of nuts to make a Ib. grown on a seedling Sero- 

 tina tree and a California, grafted with scions taken 

 from this same tree. It took forty-two nuts from 

 the mother and thirty-six from the grafted tree. 

 The nuts were not selected, but picked up as they 

 fell from the trees. 



Select choice nuts from vigorous prolific trees. 

 Put six inches of sand into a box. and lay nuts over 

 the sand. Cover the nuts with two inches of sand 

 and leave the box stand out in the winter rains. 



Do not at any time permit the nuts to become 

 dry. The germ lies in the blossom end of the nut, 

 and the shell opens at this end when the nut sprouts. 

 Usually the nut is laid on the side so a vertical line 

 would pass thru the shell when opening.
