Then he took to his oars again; and aided by the tide, which was now on the ebb, he rowed round the southwestern extremity of the island. He found the water here, as he anticipated, very shallow.
It was midday when they were fairly on the southern coast; and now, sailing with the wind aft, the cutter ran through the water at racing speed. Fearing that some reefs or rocky formations might exist in their course, he reduced sail, and kept away from the shore about a mile. At this distance he was better able to see inland, and mark down the accident of its formation.
The southern coast was uniform, and Helen said it resembled the cliffs of the Kentish or Sussex coast of England, only the English white was here replaced by the pale volcanic gray. By one o'clock they came abreast the very spot where they had first made land; and, as they judged, due south of their residence. Had they landed here, a walk of three miles across the center of the island would have brought them home.
For about a similar distance the coast exhibited monotonous cliffs unbroken even by a rill. It was plain that the water-shed of the island was all northward. They now approached the eastern end, where rose the circular mountain of which mention has been already made. This eminence had evidently at one time been detached from the rest of the land, to which it was now joined by a neck of swamp about a mile and a half in breadth, and two miles in length.
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.
Helen insisted on the preparations for their meal being left to her, and, having selected a sheltered spot, she was soon busy with their frugal food. Hazel surveyed the spot, and, selecting a red cedar, was soon seated forty feet above her head, making a topographical survey of the neighborhood. He found that the bayou by which they had entered continued its course to the northern shore, thus cutting off the mountain or easterly end, and forming of it a separate island. He saw that a quarter of a mile farther on the bayou or canal parted, forming two streams, of which that to the left seemed the main channel. This he determined to follow. Turning to the west, that is, toward their home, he saw at a distance of two miles a crest of hills broken into cliffs, which defined the limit of the mainland. The sea had at one time occupied the site where the morass now stood. These cliffs formed a range extending from north to south. Their precipitous sides, clothed here and there with trees, marked where the descent was broken by platforms. Between him and this range the morass extended. Hazel took note of three places where the descent from these hills into the marsh could, he believed, most readily be made.
On the eastern side and close above him arose the peculiar mountain. Its form was that of a truncated cone, and its sides densely covered with trees of some size.
The voice of Helen called him from his perch, and he descended quickly, leaping into a mass of brushwood growing at the foot of his tree. Helen stood a few yards from him, in admiration, before a large shrub.
