 spring, as nearly as possible, from the same place. 



Among flowering trees, the showy magnolia, the halesia, 

 red bud (Cersis chinensis), double-flowered hawthorns, with 

 white and red flowers, sophora, Japanese crab {Pyrus fori- 

 bunda), and the double-flowered plum (JPrunus triloba) 

 make exceptionally beautiful specimens. 



There are several classes of lawn trees, differing in habit 

 in shape of leaf, and in color. Some of the most picturesque 

 ones, with slender, drooping branches, are the so-called 

 weeping trees. These are available for no other purpose, 

 but are very ornamental when placed on a wide, open lawn 

 or near the margin of a lake or stream. There are two 

 classes of weeping trees : deciduous and evergreen. The 

 deciduous trees are : weeping beech, birch, willow, ash, elm, 

 and sallow, the pendulous sophora and some others. There 

 are only a few evergreen trees with drooping branches, one 

 desirable and picturesque form being a variety of the 

 Norway spruce. 



Another and equally unique class of trees is formed by 

 the fadigiate or columnar varieties of poplar, oak, birch, and 

 some coniferous trees. These, while useful as specimen 

 trees to a limited extent, are also very picturesque in a 

 shrubbery. 



Differing in the shape of the leaf only, but similar in 

 habit to the species, are the many beautiful cut-leaved 

 varieties of trees and shrubs. These varieties occur among 

 the same class of trees that produce weeping and fastigiate 

 forms, but are more numerous. There are cut-leaved 

 varieties of birch, beech, alder, sycamore, and Japanese
