ability to stand drought, good shade producing habits and general 

 freedom from plant pests. The Black Locust, Carolina Poplar, and 

 Silver Poplar are extremely valuable for very quick shade, wind 

 breaks, and should be used in all collections. The low prices at which 

 these trees can be obtained is another point in their favor. The 

 English Maple, Flowering Ash, English Oak, and European Linden 

 have all produced such strikingly attractive trees that every one who 

 sees them admires them. These trees while not so rapid of growth 

 make dense shade and are of great value for places where medium 

 sized, attractive trees are desired. 



The Cut Leaved Weeping Birch, Hardy Catalpa, Golden Willow, 

 and Colorado Blue Spruce are all so hardy and universally admired 

 that no large lawn or park should be planted without one or more of 

 these being included. The large wood producing ability of the Euro- 

 pean Larch, White Willow, Cottonwood, and Black Locust makes 

 these trees very profitable to grow for posts and fuel.
