186 TREES GROWING IN RICH SOIL. 



rounded or squared at the base ; coarsely and irregularly dentate, the sinuses 

 rounded; ribs, distinct; dark green above; paler below and covered when young 

 with a silky wool ; glabrous at maturity ; the petiole flattened. Flowers: dioe- 

 cious ; growing in long, often curving catkins ; the scales of the staminate ones 

 from five to six-cleft, sparingly fringed. The staminate trees bloom earlier 

 than the pistillate ones. 



As the specific name of this tree implies, its characteristic 

 feature is the large, coarse teeth of its leaf margins. And the 

 link of kinship between it and the delicate Populus tremuloides 

 is discernible even through the ruggedness of its foliage. As 

 the young leaves of the poplars unfold they have all a silvery 

 sheen that in the case of the willows is golden. Their 

 innumerable seeds also, when they begin to unloosen them- 

 selves from their long clusters and fly about, tint the tree and fill 

 the air with a silvery whiteness. In the autumn the leaves of 

 this species turn to such a clear, bright yellow that a luminous 

 glow is radiated by the tree to a considerable distance. We may 

 seek to find it in the deep, rich soil of woods or approaching 

 the borders of swamps. 



The wood of Populus grandidentata is soft and not generally 

 regarded as being of much value. It is made into wood-pulp 

 and later into paper.

There is something to make one tremble in the gigantic
