 hardy but produce poor fruits. Now by grafting cions from the 

 trees bearing delicious fruits on the hardy trees a^ stocks, one may 

 obtain individuals that are hardy and at the same time bear

 which are individual branches that show qualities strikingly dif- 

 ferent from other branches of the same plant. Since bud sports 

 rarely take root from cuttings or come true from seed, grafting 

 is usually the only way of preserving them; and so important 

 are bud sports that most of the best varieties of such fruits as 

 Apples, Pears, and Oranges have originated as sports, which, after 

 being grafted on stocks, became trees which by further grafting 

 have been multiplied. 



Often minor influences of the stock on the cion, such as dwarfing, 

 hastening the fruiting period, or altering the time of blossoming, 

 are desirable, and are obtained by grafting the cion on suitable 

 stocks. For example, Pears are dwarfed and fruit at an earlier 

 age when grafted on the Quince. Apples are influenced in the 

 same way when grafted on the so-called " Paradise " stock, a name
