they will grow into new plants. Grapevines are started by 

 means of cuttings. The original Concord grapevine has be- 

 come the parent of millions of grapevines scattered throughout 

 the civilized world, and this has been brought about entirely 

 by cuttings from the single original grapevine or by cuttings 

 from the descendants of it. This kind of reproduction of 

 individuals is known as vegetative reproduction, because the 

 growing plant is used directly as the means of establishing 

 new individuals. 



Different forms of grafting are in a sense types of vegeta- 

 tive reproduction, since they consist in making cuttings from 

 one plant and getting them started to grow upon another 

 plant. It will be found interesting to read agricultural and 

 horticultural books on the subject of grafting, to determine 

 what may be accomplished thereby.
