often hang upon this species through the whole of that season. 
The leaves are about four inches wide, and six in length, 
divided uniformly into rounded lobes without points; these 
lobes are deeper in damp soils. When the leaves first unfold 
in the spring, they are downy beneath, but when fully grown, 
they are quite smooth, and pale green on the upper surface, 
and whitish or glaucous below. The acorn is oval, and the 
cup somewhat flattened at the base. This is the most valua- 
ble of all our native oaks ; immense quantities of the timber 
being used for various purposes in building ; and staves of 
the white oak, for barrels, are in universal use throughout the 
Union. The great occasional size and fine form of this tree, 
in some natural situations, prove how noble an object it would 
always become when allowed to expand in full vigor and 
majesty, in the open air and light of the park. It more 
nearly approaches the English oak in appearance than any 
other American species. 
Rock Chestnut oak. ( Q. Prinus Monticola.) This is one of 
the most ornamental of our oaks, and is found in considerable 
abundance in the middle states. It has the peculiar advan- 
tage of growing well on the most barren and rocky soils, and 
can therefore be advantageously employed by the landscape 
gardener, when a steep, dry, rocky bank is to be covered 
with trees. In deep, mellow soil, its growth is wonderfully 
vigorous, and it rapidly attains a height of 50 or 60 feet, 
with a corresponding diameter. The head is rather more 
symmetrical in form and outline, than most trees of this ge- 
nus, and the stem in free, open places shoots up into a lofty 
trunk. The leaves are five or six inches long, three or four 
broad, oval, and uniformly denticulated, with the teeth more 
regular but less acute than the Chestnut white oak. When 
beginning to open in the spring, they are covered with a thick
