The White Elm is, perhaps, the most famous of 

 our American shade trees; but, in this dry soil, it will 

 not develope its full proportions, therefore it must 

 take a second place. Its top is apt to become open and 

 unsymmetrical, and it is sometimes seriously injured 

 by bark lice. For a few years after it is set out, it 

 grows slowly, but finally improves and grows quite 

 rapidly. It is so well known that it needs no especial 

 description. 



In certain localities it flourishes well. In all that 

 — sag immediately under the bluflf— it can be relied on 

 and develops well. In a few other places where the 

 ground is moist underneath, it holds no second rank. 



The European Elm requires the same kind of soil, 

 the same conditions, is equally hardy, grows as fast, 

 makes a tree of about the same dimensions and is pre- 

 ferable because the top is more upright and compact, 

 therefore making a denser shade. 



The European and American Linn are elegant 

 trees and do well. The former is the more handsome 

 of the two, and merits more attention than it has re- 

 ceived. It is preferable because it is equally hardy 

 and the top is more compact. The Linden is a historic 

 tree, and around it many romances have been woven. 

 Its foliage is elegant, and when in flower it is the most 

 fragrant tree in the temperate zone. The honey bees 

 luxuriate on it, and honey made from its flowers is 

 more delicious than any other honey in the world. 



The Lii(mbardy Poplar — Populus dilatata — is a 

 unique tree, a rapid grower, rather handsome, but is 

 very short lived. It is a native of Persia iand probably 

 other parts of Asia. It grows there and in Europe, 

 where it has been introduced and extensively culti- 

 vated, to a height of one hundred and one hundred and 

 fifty feet. In this country it rarely grows more than
