Abstract
In some deserted pits, thirty or forty feet in depth, and irregular in outline, and an acre more or less in extent, may be found Woodwardia areolata and virginica, Dryopteris patens, and a few clumps of Osmunda regalis, with small clover-like fronds, growing in the crevices of the crumbling limestone cliffs. In a digging along the railroad track, and in a washedout ravine at one of the mines, Dryopteris patens has appeared, and grows vigorously. Both places are damp and well shaded. A miniature cave, a mile to the westward, is filled with a mass of the same fern. There appears to be a spring near for the rocks are always moist.
