and the color of its foliage, the rosy pink of early spring 
changing to a dark dull green at maturity and into orange 
and brown in autumn. This oak is highly prized as an orna- 
mental tree in Europe, particularly England, Belgium, and 
Germany. It is commercially inferior to the white oak, but 
is extensively used in cooperage, cheap furniture, construc- 
tion, and interior finish of buildings. The bark is rich in 
tannin. 
Habitat: rich soil, Nova Scotia to Minnesota, south to Geor- 
gia, Tennessee and Kansas. 
Quercus Schneckii (Schneck’s oak).—This species closely 
resembles the red oak, but the sinuses of the leaves are deeper 
and the acorns are pointed. 
Habitat: Indiana, Iowa to Texas and Florida. 
Quercus palustris (pin oak) —The pin oak usually attains 
a height of from 70 to 100 feet with a trunk diameter of 3—4 
feet. It may easily be recognized by its characteristic form, 
the trunk being straight and continuous, relatively smooth, 
the crown symmetrical, conical, the lower lateral branches 
smooth and drooping, the middle horizontal, and the upper 
ascending. As the lower branches die, they leave a hard peg 
or pin which penetrates to the heart-wood, hence the name 
pin oak. This is not a very valuable species commercially, 
but it is used in construction, cooperage, interior finish, and 
for shingles. It is extremely useful in ornamental planting 
and is extensively used as an avenue tree. The leaves turn 
to brilliant scarlet in autumn. It is a comparatively fast 
grower and will grow in any rich, moderately moist soil. 
Habitat: swamps, Massachusetts to Michigan and Missouri, 
south to Tennessee and Oklahoma. 
Quercus coccinea (scarlet oak).—This is a beautiful tree 
which locally attains a height of 50 feet, with a trunk diam- 
eter of 2% feet, but which in favorable localities may reach 
a height of 150 feet with a diameter of 4 feet. It is slender 
and symmetrical, the branches and twigs gracefully curving 
to form a conical and comparatively narrow head. The leaves 
are oval or obovate, with 5-7 spreading and subdivided lobes, 
with deep, rounded sinuses and slender long petioles, smooth 
and shining above, bright red at the time of unfolding, bright 
green at maturity, and brilliant searlet in autumn. The barl
