extends, apparently, our season of rammer. Ai a shade tree it 

 is more compact and dense in its foliage, and therefore i 

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



of varieties of this species are grown from seel, ami the planter 



can frequently select a dozen trees of different nabiti among 

 those offered by the dealer as one. Nurserymen offer over 

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

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

 Twigged, Gerroteddeaved and Cork Barked (Subaroaa.) It is 

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

 autumn, and its branches and twigs covered with a fun- 

 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 Ginko — 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. 



Horse Chestnut. — Esculus. — For 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 Scotch and 

 Austrian 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 

 Yariegateddcaved, Double Red Flowering and other rar<- 

 new varieties engrafted upon the Double White Flowering. 

 The Dwarf Double Flowering {Nana Fl Pi) and of variety 

 Pavia, the Camea Superba, Camea J'ubescens, Purpurea, Rubra, 

 Flava, etc., 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. 



Hickory. — Carya.— The difficulty of transplanting the Hickory 

 or White Walnut has kept it from free use. The net of practice
