apples and sour, green varieties and red varieties. 

 And all this without any necessity for experi- 

 mentation on your part. You need have no knowl- 

 edge of plant breeding except an understanding 

 of the simple technique of grafting. 



The professional experimenters have supplied 

 the material; you have but to avail yourself of the 

 results of their work. 



Of course, if you wish to go a step farther there 

 are inviting fields that you may enter. With the 

 materials furnished by a single old apple tree you 

 may become a plant developer. You may plant 

 the seed of any choice apple purchased in the 

 market and from the seedlings you will develop 

 an interesting variety of fruits, some of which may 

 seem to you better than any existing varieties. 



We have already caught glimpses, in the out- 

 lines of my work already given, of the possibili- 

 ties of the development of various orchard fruits 

 as to size and flavor and other desirable qualities. 



If you desire to try your hand at similar im- 

 provement either of the fruit now growing on your 

 ungrafted trees, or of that growing on cions of 

 improved varieties, it will require only reasonable 

 attention to the principles already outlined in 

 earlier chapters of this work, together with a fair 

 degree of patience and persistency, to insure some 

 measure of success.
