The Large-tooth Poplar rarely if over at- 

 tains a greater height than 70 or SO ft. or 2 

 ft. in thickness of trunk. \\lu'ii sulliciently 

 isolated from other trees it (Unelops a loose 

 oval or rounded top of handsduic clciui foliaj^'o, 

 always rustling witli the sli^ditest breeze, on 

 account of the peculiar formation of petioK^s. 

 ThL^ bark of branches and younger trunks is 

 smootli and (if a grayish green color. Later it 

 becomes fissured into rough firm ridg'.'s. It is 

 found mostly on sandy slopes and the banks of 

 streams in company with the Hemlock, Pines, 

 Oaks, Maples, Shad-bush, Butternut, Red 

 Spruce, etc. As with the (^)uaking 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, paper, wooden- 

 ware and occasionally for 1 umber. i
