of tree insects. They form on the tree early in 
the spring and do not fall off until late in the 
fall. They retain their rich green color during 
the whole growing season. 
Our ideal shade tree should have a form which 
is pleasing to the eye of the beholder. This 1s 
the most difficult of all the ideal tree’s attributes 
to say anything about, for how does one describe 
the form and structure of a tree that is most likely 
to please the eye? Better to put it negatively. 
There should be no ungainly and straggling 
branches which radically break up the general 
outline of the tree. Entire branches are not liable 
to die and cause the tree to be lop-sided or 
top-heavy. 
A NEW ELM TREE IS BORN 
ITS HISTORY 
A tree new on the American scene called the 
Augustine Ascending Elm fits our description of 
the ideal shade tree in every detail and also ex- 
hibits some particular advantages. It is a natural 
mutation (that 1s, a variation) of the American 
Elm that was discovered some fifteen years ago 
in Normal, Illinois. In 
1948 an Association 
was formed to propa- VG SY, 
gate and distribute this SYS Va A 
~ 
new Elm. Because the Ur m~ aN 
Augustine Ascending y a» 
Elm bears no seed, its \ —~ 
propagation is accom- § ew VU 
plished by grafts on YAN) 
American Elm roots. 
Today it is found in 
more than 170 urban 
communities which is 
important, for six out
