so prevalent that it may be described as the normal type 
of street planting. It gives the ideal effect for which 
street shade trees have been utilized—a thoroughfare 
lined with welcome shade and graceful foliage. In most 
streets this arrangement affords the acme of decorative 
effect and 
comfort. The 
usual place 
for these is 
between curb 
and side¬ 
walk, al¬ 
though on 
narrow streets the sidewalk is sometimes next to the curb and 
the trees are back of it. A parking strip, separating walk 
from curb with a ribbon of grass, adds materially to the 
beauty of the street, serves to help protect pedestrians from 
the dust and mud of street traffic, and affords the neces¬ 
sary area for trees and their root development. It is a nar¬ 
row street that cannot spare at least 4 feet on each side for 
a parking strip of this char¬ 
acter, with its tree-planting 
possibilities. The best prac¬ 
tice adopts 4 feet as a mini¬ 
mum width for the strip; 
under no circumstances 
should a tree be planted 
nearer the curb than 2 feet 
and, where space permits, 
this should be increased. A
