While a third species, more capricious, refuse to expand at all, unless in the most brilliant sunshine, and upon the very tops of the loftiest trees.

Ambitious flowers! that will not blow, unless in high places, with the bright day looking on and admiring.
Here and there, we passed open glades in the woods, delicious with the incense of violets.

Balsamic ferns, stirred by the breeze, fanned all the air with aromas.

These glades were delightful.
Journeying on, we at length came to a dark glen so deftly hidden by the surrounding copses, that were it not for the miasma thence wafted, an ignorant wayfarer might pass and repass it, time and again, never dreaming of its vicinity.
Down into the gloom of this glen we descended.

Its sides were mantled with noxious shrubs, whose exhalations, half way down, unpleasantly blended with the piny breeze from the uplands.
