The Large-tooth Poplar rarely if ever at- 

 tains a greater height tlian 70 or 80 ft. or 2 

 ft. in thickness of trunk. Wlicii sullicieiitly 

 isolated from otlu-r trws it devi-lops a loose 

 oval or rounded top of liimdsoinc clcnii foliajic 

 always rustling with the slightest lucczo, (Mi 

 account of the peculiar formation of petioles. 

 The hark of hranches and younger trunks is 

 smooth and of a grayish green color. Later it 

 becomes fissured into rough lirni ridges. It is 

 found mostly on sandy slopes and the baidcs of 

 streams in company with the Hemlock, Pines, 

 Oaks, Maples, 8had-l)ush, Butternut. Red 

 Spruce, etc. As with the Quaking Asp, its 

 hardy seeds scattered widely by the wind 

 quickly clothe with new verdure tracts of 

 forest lands recently denuded by fires. Then 

 protected by the shade of these seedlings the 

 more tender seeds of more useful trees are able 

 to germinate and grow. 



Its wood is light, a cubic foot weighing 

 28.87 lbs., soft and not strong and is used in 

 the manufacture of excelsior. ])aper, wooden- 

 ware and occasionally for lumber. i
