 great depths they still possess the 

 power of germinating. 



There are other kinds of Pop- 

 lar with angular stems, but they 

 are distinguished from the pres- 

 ent species by having resinous 

 and aromatic buds, like the Bal- 

 sam Poplar, and the Balm of 

 Gilead Poplar, while the buds of 

 this species are destitute of aro- 

 matic gum. The wood is soft,

 river. The angled Cottonwood 

 does not appear to extend up the 

 Mississippi river beyond Lake 

 Pepin.

Milwaukee is just on the south-

 few small specimens having been 

 observed on the lake and river 

 banks near that city. It is more 

 abundant in the northern por- 

 tions of the State. It resembles 

 the next species in the agreeable 

 odor of the buds in the spring, 

 but wants its vigorous growth, 

 and great size; and the leaves
