extends, appai-ently, our season of summer.' As a shade tree it 

 ia more compact aaid dense in its foliage, and therefore more 

 suitable in. the formation of masses or groups.. A great number 

 of varieties- of this species are grown from seed, and the planter 

 can frequently select a dozen trees of different hahits among^ 

 those offered by the dealer as one. Nurserymen offer over 

 twenty-five as distinct varieties. A few of them are of due 

 credit and value as novelties, viz. : The Purple-leaved, Slender 

 Twigged, Gerroted-leaved and Cork Barked (Siiberosa.) It is 

 vigorous and hardy, foliage rich and dark, hanging late in 

 autumn, and its branches and twigs covered with a fungous 

 growth of a cork like substance,, so singular and curious as to 

 attract attention and admiration. The foliage of all the elms in 

 autumn is of a yellow tint. 



The Oinko — Salisburia. — A tree with foliage unlike any other. 

 In form it has generally a neat, regular,, open, conical head.; its. 

 foliage on long petioles, giving it an airy and unique appearance- 

 that harmonizes well with buildings,, but does.not. so well with, 

 masses or groups of other trees. 



Bbrse Chestnut — Esculusi — Ear bordering the lines of straight 

 avenues»and for public, squares or town plots, where regularity 

 and symmetry are desired rather than grandeur, for single lawn 

 trees and for limited use in grouping with the Scoteh and 

 Aua.trian Pines, the Horse Chestnut is one of our best and most 

 ornamental trees. The old, white flowering has now given place 

 to, one of the same habit, in growth, but producing double white 

 flowers. Where the ground is limited, it is well to have the 

 Variegated-leaved, Double Eed Flowering and other rare and 

 new varieties engrafted upon the Double "White Flowering. 

 The Dwarf Double Flowering {Nana Fl. PI.) and of variety 

 Pavia, the. Camea Superba, Cornea Pubescens, Purpurea, Rubra, 

 Flava, elc.,. come into use along a line or as a group at a turn of 

 the road. The growth of these is in no case of. value, other than 

 a low group of broad leaved shrubs.,
