48 FLOWER-GARDENING. 



Having had two or three years' growth on these rows, they maj 

 be planted successfully in any warm and tolerably rich sandy 

 soil. They may also be propagated by suckers, which they 

 throw up abundantly, especially if some of the wide-extending 

 roots be cut through with an axe. An acre of these trees, 

 planted at two feet distant each way, will contain 10,890 ; and 

 four feet distant, 2,722 ; and it is said that no appropriation of 

 land is more lucrative than that devoted to this purpose. The 

 Three-thorned Acacia seed (Gleditschid) should be prepared in 

 the same manner. 



Rosa, or Roses, a very numerous variety of these ; some 

 reckon five or six hundred kinds. They are accounted the 

 most beautiful of Flora's productions. Perhaps a handsome 

 collection might be made out of about fifty of the best sorts, 

 which by taking such quantity I suppose might be obtained 

 at about fifty cents each, under name ; and generally, a fine 

 collection unnamed at half that amount. No good garden or 

 shrubbery should be without them. 



Sorbus aucuparia, Mountain Ash, or Roan tree. This is a very 

 beautiful shrub of the larger size ; the leaves are ornamental ; 

 the flowers and fruit, which are produced in large bunches, are 

 beautiful ; the fruit remains till late in the autumn. It is a 

 native of Europe. 



Sorbus Canadensis. This is a native of our Northern fron- 

 tiers and mountains, but it does not grow so large as the 

 former ; the berries are smaller and red, the former larger and 

 of an orange color ; but otherwise much resembles it. 



Spartium junceum, Gentista, etc. Two or three species of 

 Broom, producing numerous bunches of yellow flowers in May 

 and June ; the Genista, or Spanish Broom, which has white 

 flowers, is also very pretty, but not quite so hardy as the 

 former. 



Symphoria racemosa, or Snow-berry, sometimes called St. 

 Peter's Wort, a pretty little shrub ; the bunches of wax-like 

 white berries which it produces during the whole summer 

 give it a beautiful appearance.
