 it will thrive even on very sandy soils, 

 if of proper depth. Uses The black 

 mulberry is chiefly cultivated for its 

 fruit, and the white mulberry for its 

 leaves, which are considered the best 

 for the silk-worm. It has been 

 long ago recommended that, instead 

 of pulling the leaves off singly for the 

 food of the silk-worm, they should be 

 shorn off, together with their young 

 branches, by which the tree is much 

 less injured.

Uses. the wood of the European 

 nettle-tree is considered to be one of 

 the hardest ; and Evelyn says, that in 

 former times it WAS used for the ma- 

 nufacture of musical instruments. 

 The American nettle-tree is similar 

 in its foliage and general appearance 

 to the European species ; the branches 

 of both are numerous and slender, 

 and the limbs take their rise at a 

 small distance from the ground, 

 and grow in a horizontal or an in- 

 clined direction. Michaux observes, 

 that the comparative value of the 

 wood has not been proved in Ame- 

 rica, but that it is similar in proper- 

 ties to the former species. As yet 

 those other species enumerated above 

 are considered as merely ornamental.

Pentandria Digynia. Linn. 

 CALYX five-cleft, inferior, permanent j co- 

 rolla, none ; seed-vessel, compressed, flat, 

 one-seeded; seed, roundish, slightly com- 

 pressed. 



Time of sowing the seed As soon as 

 ripe in May, on a bed of fresh loamy 

 earth to be shaded from the mid-day 

 sun, until the plants appear to be well 

 rooted. The Wych elm is almost the 

 only species raised from seed; the 

 other species are raised by layers. 

 The American elms produce seed, but 

 it seldom retains its vegetative powers 

 long enough to be brought to Eng- 

 land. A deep loam grows the elm to 

 the greatest perfection. Uses The 

 wood is hard and tough, and resists 

 the effects of moisture better than 

 most other kinds of wood. Its tena- 

 cious adhesive quality renders it va- 

 luable for many important purposes, 

 keels of ships, naves of wheels, &c.
