Hazel proposed to reconnoiter this part of the shore nearly, and ran the boat close in to land. The reeds or canes with which this bog was densely clothed grew in a dark, spongy soil. Here and there this waste was dotted with ragged trees which he recognized as the cypress. From its gaunt branches hung a black, funeral kind of weeper, a kind of moss resembling iron-gray horse-hair both in texture and uses, though not so long in the staple. This parasite, Hazel explained to Helen, was very common in such marshy ground, and was the death-flag hung out by Nature to warn man that malaria and fever were the invisible and inalienable inhabitants of that fatal neighborhood. Looking narrowly along the low shore for some good landing, where under shelter of a tree they might repose for an hour, and spread their midday repast, they discovered an opening in the reeds, a kind of lagoon or bayou, extending into the morass between the highlands of the island and the circular mountain, but close under the base of the latter. This inlet he proposed to explore, and accordingly the sail was taken down, and the cutter was poled into the narrow creek. The water here was so shallow that the keel slid over the quicksand into which the oar sank freely. The creek soon became narrow, the water deeper, and of a blacker color, and the banks more densely covered with canes. These grew to the height of ten and twelve feet, and as close as wheat in a thick crop. The air felt dank and heavy, and hummed with myriads of insects. The black water became so deep and the bottom so sticky that Hazel took to the oars again. The creek narrowed as they proceeded, until it proved scarcely wide enough to admit of his working the boat. The height of the reeds hindered the view on either side. Suddenly, however, and after proceeding very slowly through the bends of the canal, they decreased in height and density, and they emerged into an open space of about five acres in extent, a kind of oasis in this reedy desert, created by a mossy mound which arose amid the morass, and afforded firm footing, of which a grove of trees and innumerable shrubs availed themselves. Helen uttered an exclamation of delight as this island of foliage in a sea of reeds met her eyes, that had been famished with the arid monotony of the brake. They soon landed.
