Leaves rolled inwards, with 2 glands running one into the 

 other on the inner side above the base. Linn. Leaf-stalks flatted 

 towards the end, whence the trembling of its leaves. Gouan. 

 The same takes place in S. alba and nigra. The plane of the 

 leaf-stalks is at right angles to that of the leaves, which allows 

 the leaves a much freer motion than could have taken place had 

 their planes been parallel. St. Leaves more circular than in the 

 preceding.

Leaves without any glands at the base, but the serratures 



* It loves low situations, and flourishes best in clay. It grows quick, 

 and bears cropping, but it is unfavourable to pasturage. The wood is soft, 

 ^vhite, and stringy, and makes good wainscoting, being but little subject 

 *o swell or shrink. Floors, laths, packing boxes, and turners ware are 

 niade of it. Horses, sheep, and goats eat it. Cows are not fond of it. 



,+ It will grow in all situations, and in all soils, but worst in clay. 

 *t impoverishes the land ; its leaves destroy the grass, and the numerous 

 shoots of the roots spread so near the surface of the earth, that they will 

 n ot permit any thing else to grow. It is easily transplanted. The wood 

 J* extremely light, white, smooth, woolly, soft ; durable in the air. The 

 b *rk is the principal food of beavers. The bark of the young trees is 

 niade into torches. The leaves and leaf-stalks sometimes are set with red 

 ^lobular substances, about as large as a pea, which are the nests of the 

 2 ''pula juniper ina % Sheep and goats eat it ; horses and swine refuse it.
