ORNAMENTAL AND SHADE TREES— Continued : 
SALIX - Willow : a / 
Besides the beauty of their airy Summer foliage the Willows have a dis- 
tinct value in the brightness of their bark when leaves have fallen. There 
are few trees that can be used to such advantage for cheery Winter effects. 
They grow fast and are adapted to a variety of soils and uses. Frequent 
cutting back gives a thicker growth of bright young twigs. 

Salix blanda (Wisconsin Weeping Willow). Of drooping habit and hardier 
than Salix babylonica. Valuable on account of its ability to resist severe 
cold. 
S. discolor (Pussy Willow). See description under Shrubs, page 34. 
MEH ER 
Ege 
: 
S. elegantissima (Thurlow Weeping Willow). Rapid growing weeper but 
with very brittle branches. 
S. pentandra (Laurel Willow). Ornamental tree of upright growth; bark 
brownish green, leaves dark, glossy green; excellent for seashore planting. 
SORBUS - Mountain-Ash 
Sorbus aucuparia (European Mountain-ash). Medium-sized tree, with 
handsome, pinnate leaves, neat habit and showy crops of bright red ber- 
ries, persistent until late in 
Winter, giving a brilliant note 
to the Autumn landscape. 
Hardy, erect, 20 to 30 ft. 
high with smooth bark and 
dense, regular heads; berry 
clusters large and bright. 

ULMUS - Elm 
Ulmus americana (American Elm). Easily distinguished by its wide-arching top, 
vase-like form and pendulous branchlets. Next to the Oak, this is the grandest 
and the most picturesque of American trees. Attains 80 to 100 ft. Dull yellow or 
brown in Fall. 
U. moline (The Moline Elm). A select strain. Grows vigorously and quickly, develop- 
ing into a dense, conical specimen with a central leader. Smooth, clear gray bark. 
U. glabra camperdowni (Camperdown Elm). One of the finest drooping lawn trees. 
The branches spread horizontally in an attractive way and then gracefully turn 
down, forming a picturesque natural arbor. 
U. pumila (Chinese Elm). Faster growing than any other Elm and often reaches 
80 ft. in height. Regular in growth when pruned. In youth and in middle age it is 
pyramidal in outline. Dark gray bark. Exceedingly useful as a street tree in cities 
as it does not seem to mind smoke. Despite its unusual speedy growth, the wood 
is hard and tough as birch. No faults except that it is not graceful when it reaches 
Chinese Elm very old age; can also be used as a tall hedge plant when closely pruned and trimmed. 

HOW GREENING’S MAINTAIN ENORMOUS TREE PRODUCTION 
Another Cost Cutting Greening Invention. Created, Designed and Built 
in Greening Research Shops 



The Greening 
TREE PLANTER 
Truly a mechanical marvel. 
Note that feeders ride back- 
wards, feeding mechanical 
planters which automatically 
correctly space and plant two 
rows at once. On this machine 
a revolving cutter opens a ce ee es ee 
trench 4 inches wide, 8 inches # . 
deep. Removed soil is pulver- 
ized and placed at one side. 
The shoe holds trench open, 
suides the plant roots and loose 
soil is returned to trench and 
firmed by drive wheels. Pow- 
ered by an 80-horse power en- 
gine, the machine plants 52,000 
seedlings a day. Two such ma- 
chines are required to handle 
our Spring plantings. be
