It is probable that they understood the art in all its

6. Hybridization. — This operation is employed for the 

 purpose of producing new varieties. It consists of im- 

 pregnating the flowers of one variety with the pollen of 

 another, in the hope that the good qualities of the parents 

 may be transmitted to the ofispring. Thus, if we have 

 one variety which is early and hardy, but the quality 

 poor, and another variety of good quality, but too tender 

 for out-door culture, by making a cross between the 

 two, we may get a new variety which combines the good 

 qualities of one parent with the hardiness of the other. 

 The seed of the fruit which results from the flowers, after 

 receiving the cross impregnation, are planted and fruited 

 in the manner described under the head of 23roj)agation 

 by seed.
