NATIVE TREES 



they are stately and dignified when standing 

 alone, and produce arched, vaulted avenues in 

 street planting. Ulmus americana and Ulmus 

 campestris — American and English Elms — are 

 the most popular, although Ulmus pubescens — 

 Slippery Elm — is often planted, and is exceed- 

 ingly attractive in the spring when the trees are 

 massed with light green, winged samaras. Cel- 

 tis occidentalis — Hackberry — is highly recom- 

 mended as an ornamental tree. Where it attains 

 its highest development it has a fine round- 

 topped head, pendulous branches, and a stri- 

 kingly characteristic bark. The leaves become 

 golden yellow in the autumn, and persist some 

 time after the other trees have shed their leaves. 

 It endures varied soil conditions, is free from 

 insects, and bears dark berries, which are at- 

 tractive to birds in winter. 



The Maples have many good qualities to 

 commend them. Acer saccharinum, or Sugar 

 Maple, is one of the most beautiful of the forest- 

 trees, and for street planting nothing surpasses 

 it. Symmetrical in growth, it produces dense 

 shade, and turns the most brilliant color in the 

 autumn. Acer ruhrum, or Soft Maple, has 

 finely cut leaves with long, slender petioles, 

 which respond to the wind, disclosing the silvery 

 whiteness of the under surface of the leaves. 

 Its autumn dress is yellow, and contrasts well
