The Sweet Birch attains the height of 70 or 

 SO ft., with a trunk diameter of from 2-5 ft., 

 and when growing away from otlier trees de- 

 velops a symmetrical ovoid or pyramidal top 

 at first with many strong small branches, but 

 finally roundeil or broad by the lengthening 

 of the lateral branches. The bark of trunk is 

 at first smooth and peels off transversely in 

 thin strips, but finally becomes fissured with 

 large and small irregular scales suggesting 

 the bark of the Black Cherry, for which reason 

 the tree is sometimes called the Cherry Birch. 

 The darki;?ss of its color gives it the name of 

 Black Birch and from the sweet aromatic flavor 

 of its leaves and bark it is called the Sweet 

 Birch. It flourishes on rich well-drained up- 

 lands, and in early spring while the branches 

 are bare of leaves and it is trimmed with its 

 golden tassels of catkins, unloading their 

 pollen on the lightest touch, it is a particu- 

 larly handsome object. 



The wood is heavy, hard and strong, a cubic 

 foot when absolutely dry weigliing 47.47 lbs., 

 and is valued in the manufacture of furniture, 

 agricultural implements and general wooden 

 ware, and for fuel.i
