 sion by members of the Western Walnut Growers Association. When grafting is done low 

 down on the ground the graft will start and then die. Hence better results are obtained 

 from trees grafted some distance above the ground. It was found that fine crops may be 

 obtained when the grafting is carried out 12 feet above the surface of the ground. — E. L.
