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 ; at 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, (Gle- 

 ditschia) should be prepared in the same manner.] 



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 

 frontiers and mountains; it does not grow as large as 

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

 larger and of an orange colour, but otherwise much 

 resemble it. 



Spartium junceum, and Genista, two or three spe- 

 cies of broom, with bunches of yellow flowers in very 

 great profusion; the Genista or Spanish broom has 

 white flowers, is also very pretty, but not quite so 

 hardy as the former. 



Symphoria racemosa, or Snow-berry, sometimes call- 

 ed Snow-apple, a pretty little shrub ; the bunches of 

 wax-like white berries which it produces during the 

 whole summer, give it a beautiful appearance. 



Syringa vulgaris, or common Lilac, is well known
