be quite difficult to establish them as street trees; 
they would not take kindly to the bare soil of the plant- 
ing strip, nor grow under the pavement edge. As a lawn 
tree, however, they are to be recommended. Some of them 
grow very large and all of them are long-lived. It is 
one of the few trees whose unfolding buds in spring are 
as colorful and interesting as the flowers of some of our 
best ornamentals. On the whole, the family has its quota 
of insect pests, but none of them so serious that one 
would hesitate to recommend the planting of Hickories. 
It is not a tree to be injured by late frosts. It is 
well adapted to Missouri springtime, and just patiently 
waits for settled weather before growing. The large 
fruits of some varieties may make them objectionable, but 
if there are any squirrels in the neighborhood, it will 
be unnecessary to rake hickory nuts from the lawn. One 
of the biggest Hickories adapted to very good soils is 
the King Nut, (Carya laciniosa) . It resembles the Shag 
Bark Hickory, (C. Ovata) , and both have the bark charac- 
teristically separating into long shaggy strips. These 
are both extremely large trees developing a trunk in ex- 
cess of four feet in diameter. For drier situations, the 
Mockernut (C. Tomentosa), and its varieties will prove 
quite satisfactory. They make excellent lawn trees, hav- 
ing large leaves, growing tall, but differing from the . 
first two in that they have tight-ridged bark. The terra 
Pig Nut Hickory is applied to half a dozen species and 
varieties. Most of them are small trees growing on dry 
locations, and with small fruit and rather small leaves. 
Of these, only the Pig Nut or Bitter Nut, known techni- 
cally as C. Cordiformis, would be suitable for lawn or 
street use. This is the Hickory with small buds, yellow 
in color, whfich are the best distinguishing feature. It 
may grow to immense size, but it does not tend to develop 
heavy side branches, and even as a specimen, it will grow 
much taller than it will spread. A nearly perfect shade 
tree for the larger suburban lot. The native Pecan (C 
Pecan) can be found in the flood plain of both the Mis- 
souri and Mississippi Rivers. It is not likely to be 
happy as a shade tree. It requires the deep rich soil 
and the moisture found in the river valleys.
