pests and diseases. The Verticillum Wilt does much harm 
in some years, especially to northern trees when planted 
in the Middle West. The Black Maple (A. Nigrum) is a 
somewhat slower growing edition of the Sugar Maple, with 
clear yellow leaves in fall. It is rather difficult to 
distinguish from the Sugar Maple, but it could be used as 
a street or lawn tree throughout the Middle West. On the 
whole, it tends to a more compact growth with shorter and 
smaller branches than the Sugar Maple. The Sycamore 
Maple (A. Pseudoplatanus) is one of the oldest Maples in 
cultivation and gardeners have had time to develop many 
forms and types. In the Middle West, it does not grow to 
great size. It is generally a tree not much over thirty 
feet, with large Sycamore- like leaves, and usually with- 
out enemies. It would make a superb lawn tree with 
either the normal green or purple variegated leaves. It 
spreads too much for street use, but it has a place in 
wider parkways. The Little Amur Maple (A. Ginnala) may 
reach a height of twenty feet, but normally, it is much 
smaller and can be thought of as a shrub rather than a 
tree. However, it can be grown with a single leader, and 
therefore, would become a splendid small tree for lawn 
use. Both the fruit and the foliage become brilliant 
red, the fruit when ripened and the leaves in fall. The 
Japanese Maple (A. palmatum) and its many ornamental 
forms are interesting and have a place in our gardens, 
but they are not suitable for street use. If grown with 
a single leader, they become interesting plants, usable 
even in the smallest gardens. The Scarlet or Red Maple 
{A. rubrum) is primarily a tree of the northern country. 
It is rather slow growing south of its normal range, and 
It may sucker so freely from the ground level that it can 
be forced into the habit of a tree only by very careful 
pruning. Eventually specimens grow taller and assume the 
Characteristics of a tree, and about this time, they be- 
gin to exhibit the interesting red flowers and fruits. 
Several varieties are available; the most important is a 
columnar form likely to prove to be an excellent street 
tree. In the Ozark region, a small variety (A. r. 
tnlobum) having a leaf with three lobes instead of the 
usual five can be found in some of the acid soil areas, 
fhis would make an interesting tree for the exacting gar- 
dener. The Swamp Red Maple (A. r. Drummondi) is perhapS 
the southernmost of the Red Maples. It is unusual
