<6o TREE-PLANTING. 



Of the Cork-barked elm (U. stiberosa), there are 

 several varieties, as well as the American elm, the 

 Curled-leaved elm, and the Variegated elm. The most 

 graceful of the entire genus is the Ulmus pendula, or 

 Weeping elm, of which \ there are several varieties, 

 supposed to have sprung from the Wych elm, being 

 begun to be cultivated in nurseries about the end of 

 the last century. 



It seeds freely, but as plants raised from seed 

 are apt to lose the peculiarities of their species, it is 

 generally propagated by being grafted upon a stock 

 of the common elm. In this way it grows readily, 

 .and soon forms a head of considerable size, often 

 presenting a most striking appearance, being wild, 

 diversified, and rugged, in the eccentricity of its 

 growth sometimes sending out its branches upwards, 

 downwards, horizontally, or obliquely, in a manner 

 which is never seen in the case of any other tree. As 

 3, tree for the lawn, park, or pleasure ground, it is 

 very desirable amongst the fast-growing trees, in 

 -effect somewhat resembling the cedar. 



A species of elm very common to Britain in some 

 parts is the U. glabra, being of rapid growth, and 

 having many varieties. 



The aptitude, however, of the elm, throughout all 

 its varieties, to vary from seed, has rendered the 

 genus very confused, and it is therefore of importance 

 that the planter knows himself to be possessed of the 

 best kind adapted for the purposes intended. 



The Chestnut Tree (Castanea vescd}. Linnaeus has 

 united the genus Castanea with Fagiis, the beech, 

 which has not however been done by previous bota- 

 nists, nor has his example been followed by many
