The Large-tooth Poplar rarely it ever at- 

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

 ft. in thickness of trunk. Wlien sufficiently 

 isolated from other trees it develops a loose 

 oval or rounded top of handsome clean foliage, 

 always rustling with the slightest breeze, on 

 account of the peculiar formation of petioles. 

 The bark of branches and 3'ounger trunks is 

 smooth and of a grayish green color. Later it 

 becomes fissured into rough firm ridges. 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 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, paper, wooden- 

 ware and occasionally for lumber. 1 



Leaves orhicular-ovate, 3-f! in. long, coarsely 

 and irregularly dentate, from obtuse to rounded 

 at base, short acuminatp, densely white tomentose 

 at first hut finally glabrous, thin and fli'm ; petioles 

 long, slender and laterally compressed : winter 

 buds puberulous. Flairrys: aments 1-.^ in. long: 

 scales with silliy pale hairs and irregularly .5-7- 

 rlctt ; stamens fi-12 : stiimas 2 with long filiform 

 lobes. Fruit (May-.Tune) : capsules long-conic. 2-
