lands, we enter upon
the dry prairies, extending up the bluffs, where we meet the small
vermilion Sorrel _(Rumex acetosella)_ and Mouse-ear, which, however, do
not reside here as foreigners, but as natives, like many other plants
that remind the European of his native country, as, for instance, the
Dandelion _(Taraxacum officinale)_; a kind of Rose, _(Rosa lucida,)_
with its sweet-scented blossoms, has a great predilection for this dry
soil. With surprise we meet here also with many plants with hairy,
greenish-gray leaves and stalk-covers, as, for instance, the _Onosmodium
molle, Hieracium longipilum, Pycnanthemum pilosum, Chrysopsis villosa,
Amorpha canescens, Tephrosia Virginiana, Lithospermum canescens;_
between which the immigrated Mullein _(Verbuscum thapsus)_ may be found.
The pebbly fragments of the entire slope, which during spring-time
were sparingly covered with dwarfish herbs, such as the _Androsace
occidentalis, Draba Caroliniana, Plantago Virginica, Scutellaria
parvula,_ are now crowded with plants of taller growth and variegated
blossoms. _Rudbeckia hirta_, with its numerous radiating blossoms of a
lively yellow, and the closely allied _Echinacea purpurea_, whose long
purple rays hang down from a ruddy hemispherical disc, are the most
remarkable among plants belonging to the genus _Compositoe_, which
blossom early in summer; in the latter part of summer follow innumerable
plants of the different species,_Liatris, Vernonia, Aster, Solidago,
Helianthus, etc."_

"We approach a sinuous chasm of the bluffs, having better soil and
underwood, which, thin at first, increases gradually in density.
Low bushes, hardly a foot high, are formed by the American Thistle,
_(Ceanothus Americanus,)_ a plant whose leaves were used instead of tea,
in Boston, during the Revolution. Next follow the Hazel-bush, _(Corylus
Americana,)_ the fiery-red _Castilleja coccinea,_ and the yellow
Canadian Louse-wort; the _Dipteracanthus strepens_, with great blue
funnel-shaped blossoms, and the _Gerardia pedicularia_, are fond of
such places; and where the bushes grow higher, and the _Rhus glabra,
Zanthoxylum Americanum, Ptelea trifoliata, Staphylea trifolia,_ together
with _Ribes-Rubus Pyrus, Cornus, and Cratoegus,_ form an almost
impenetrable thicket, surrounded and garlanded by the round-leaved,
rough Bindweed, _(Smilax rotundifolia,)_ and _Dioscorea villosa_, the
Climbing Rose, _(Rosa setigera,) Celastrus scandens_, remarkable for its
