Ill STORY OF THE APPLE. 51 



Tiger Lily by bulblets, some onions by proliferous bulbs, 

 sugar cane by planting pieces of the stalk, many grapes by 

 horizontal stems, and many plants by cuttings, for a very 

 great length of time. The grape vine has been continued 

 in this way from the days of the Romans. A slip taken 

 from a willow in Mr. Knight's garden pronounced by him 

 to be dying from old age, was planted in the Edinburgh 

 Botanic Garden many years ago, and is now a vigorous 

 tree, though the original stock has long since gone to de- 

 cay.*
