brown globular growths known as cedar apples. Treat¬ 
ment is not always necessary, but when it is needed, 
Bordeaux mixture should be applied before the leaves 
open in the spring, and several times during July and 
August, at two to four week intervals. Removal of the 
“apples” from Cedars in the early spring is advisable, 
especially if they are near apple trees, as the cedar apples 
can readily produce rust on apple trees. 
Leaf scorch is an ailment which causes young leaves 
and tender shoots to wither and die. It is apt to make its 
appearance during a dry, hot spell, following a damp 
spring. Many varieties of trees are affected, but Maples 
seem to suffer most. Helpful treatment may be given by 
keeping the soil well watered and freely cultivated when 
the dry season comes, so that moisture and air may reach 
the root system for the thorough nourishing of the tree. 
Poor soil conditions are the cause of many ailments of 
street shade trees. A common manifestation of trouble 
of this nature is known as stag-head or top-dry, which 
results in slow death of the top, producing an effect sug¬ 
gesting the bare horns of a stag. This is apt to indicate 
lack of water or suffocation of the roots. Enrichment of 
the soil, a plentiful supply of water and frequent loosening 
of the soil by cultivation, are necessary to bring about 
recovery of an affected tree.
