grafted on the Mountain Ash. 
Ruamnus caTHarticus. (Buckthorn.) 
The common Buckthorn is often cultivated as a hedge- 
plant. It is a native of Europe, but has become natu- 
ralized in many parts of the country, especially in the At-

it is quite an ornament. Its seeds are contained in a 
berry, and are quite hard; should be sown in fall, or kept 
in moist sand during winter, and if where frozen, all the

R. ALNiFotius is a Northern species; but it is only a 
small shrub. 
SASSAFRAS OFFICINALE. (Sassafras.) 
The Sassafras-tree is seldom planted for ornament ; but 
there is no reason why it should not be introduced for 
this purpose, as it is a very handsome tree, and probably 
would be often planted if it were not for the uncertainty 
of making it live, it being one of the most difficult trees to 
transplant that we possess, having long, soft, naked roots 
which run very deep in the soil. If it is desirable to move
