"What is it?" said she.

"One of the most valuable productions of the earth. It is cochineal. This is the Tunal tree."

"Oh, indeed," said Helen, indifferently. "Cochineal is used for a dye; but as it is not probable we shall require to dye anything, the discovery seems to me more curious than useful."

"You wanted some ink. This pigment, mixed with lime-juice, will form a beautiful red ink. Will you lend me your handkerchief and permit me to try if I have forgotten the method by which these little insects are obtained?" He asked her to hold her handkerchief under a bough of the Tunal tree, where the fruit was ripe. He then shook the bough. Some insects fell at once into the cloth. A great number rose and buzzed a little in the sun not a yard from where they were born; but the sun dried their blood so promptly that they soon fell dead in the handkerchief.

Those that the sun so killed went through three phases of color before their eyes. They fell down black or nearly. They whitened on the cloth; and after that came gradually to their final color, a flaming crimson.

The insect thus treated appeared the most vivid of all.

They soon secured about half a teacupful; they were rolled up and put away, then they sat down and made a very hearty meal, for it was now past two o'clock. They re-entered the boat, and, pa.s.sing once more into the mora.s.s, they found the channel of the bayou as it approached the northern sh.o.r.e less difficult of navigation. The bottom became sandy and hard, and the presence of trees in the swamp proved that spots of _terra firma_ were more frequent. But the water shallowed, and, as they opened the sh.o.r.e, he saw with great vexation that the tide in receding had left the bar at the mouth of the ca.n.a.l visible in some parts. He pushed on, however, until the boat grounded. This was a sad affair. There lay the sea not fifty yards ahead. Hazel leaped out, and examined and forded the channel, which at this place was about two hundred feet wide. He found a narrow pa.s.sage near the eastern side, and to this he towed the boat. Then he begged Miss Rolleston to land, and relieved the boat of the mast, sail, and oars. Thus lightened, he dragged her into the pa.s.sage; but the time occupied in these preparations had been also occupied by Nature--the tide had receded, and the cutter stuck immovably in the waterway, about six fathoms short of deeper water.

"What is to be done now?" inquired Helen, when Hazel returned to her side, panting, but cheerful.

"We must await the rising of the tide. I fear we are imprisoned here for three hours at least."

There was no help for it. Helen made light of the misfortune. The spot where they had landed was inclosed between the two issues of the lagoon.

They walked along the sh.o.r.e to the more easterly and the narrower ca.n.a.l, and, on arriving, Hazel found to his great annoyance that there was ample water to have floated the cutter had he selected that, the least promising road. He suggested a return by the road they came, and, pa.s.sing into the other ca.n.a.l, by that to reach the sea. They hurried back, but found by this time the tide had left the cutter high and dry on the sand.

So they had no choice but to wait.

Having three hours to spare, Hazel asked Miss Rolleston's permission to ascend the mountain. She a.s.sented to remain near the boat while he was engaged in this expedition. The ascent was too rugged and steep for her powers, and the sea-sh.o.r.e and adjacent groves would find her ample amus.e.m.e.nt during his absence. She accompanied him to the bank of the smaller lagoon, which he forded, and waving an adieu to her he plunged into the dense wood with which the sides of the mountain were clothed.

She waited some time, and then she heard his voice shouting to her from the heights above. The mountain-top was about three-quarters of a mile from where she stood, but seemed much nearer. She turned back toward the boat, walking slowly, but paused as a faint and distant cry again reached her ear. It was not repeated, and then she entered the grove.

The ground beneath her feet was soft with velvety moss, and the dark foliage of the trees rendered the air cool and deliciously fragrant.

After wandering for some time, she regained the edge of the grove near the boat, and selecting a spot at the foot of an aged cypress, she sat down with her back against its trunk. Then she took out Arthur's letter, and began to read those impa.s.sioned sentences; as she read she sighed deeply, as earnestly she found herself pitying Arthur's condition more than she regretted her own. She fell into reverie, and from reverie into a drowsy languor. How long she remained in this state she could not remember, but a slight rustle overhead recalled her senses. Believing it to be a bird moving in the branches, she was resigning herself again to rest, when she became sensible of a strange emotion--a conviction that something was watching her with a fixed gaze. She cast her eyes around, but saw nothing. She looked upward. From the tree immediately above her lap depended a snake, its tail coiled around a dead branch. The reptile hung straight, its eyes fixed like two rubies upon Helen's, as very slowly it let itself down by its uncoiling tail. Now its head was on a level with hers; in another moment it must drop into her lap.

She was paralyzed.

CHAPTER XXVIII.

AFTER toiling up a rugged and steep ascent, enc.u.mbered with blocks of gray stone, of which the island seemed to be formed, forcing his way over fallen trees and through the tangled undergrowth of a species of wild vine, which abounded on the mountain-side, Hazel stopped to breathe and peer around as well as the dense foliage permitted. He was up to his waist in scrub, and the stiff leaves of the bayonet plant rendered caution necessary in walking. At moments, through the dense foliage, he caught a glisten of the sea. The sun was in the north behind him, and by this alone he guided his road due southerly and upward. Once only he found a small cleared s.p.a.ce about an acre in extent, and here it was he uttered the cry Helen heard. He waited a few moments in the hope to hear her voice in reply, but it did not reach him. Again he plunged upward, and now the ascent became at times so arduous that more than once he almost resolved to relinquish, or, at least, to defer his task; but a moment's rest recalled him to himself, and he was one not easily baffled by difficulty or labor, so he toiled on until he judged the summit ought to have been reached. After pausing to take breath and counsel, he fancied that he had borne too much to the left, the ground to his right appeared to rise more than the path that he was pursuing, which had become level, and he concluded that, instead of ascending, he was circling the mountain-top. He turned aside therefore, and after ten minutes' hard climbing he was pushing through a thick and high scrub, when the earth seemed to give way beneath him, and he fell--into an abyss.

He was ingulfed. He fell from bush to bush-- down-- down-- scratch-- rip-- plump! until he lodged in a p.r.i.c.kly bush more winded than hurt. Out of this he crawled, only to discover himself thus landed in a great and perfectly circular plain of about thirty acres in extent, or about three hundred and fifty yards in diameter. In the center was a lake, also circular. The broad belt of sh.o.r.e around this lake was covered with rich gra.s.s, level as a bowling green, and all this again was surrounded by a nearly perpendicular cliff, down which indeed he had fallen. This cliff was thickly clothed with shrubs and trees.

Hazel recognized the crater of an extinct volcano.

On examining the lake he found the waters impregnated with volcanic products. Its bottom was formed of asphaltum. Having made a circuit of the sh.o.r.es, he perceived on the westerly side--that next the island--a break in the cliff; and on a narrow examination he discovered an outlet.

It appeared to him that the lake at one time had emptied its waters through this ancient water-course. The descent here was not only gradual, but the old river-bed was tolerably free from obstructions, especially of the vegetable kind.

He made his way rapidly downward, and in half an hour reached marshy ground. The cane-brake now lay before him. On his left he saw the sea on the south, about a third of a mile. He knew that to the right must be the sea on the north, about half a mile or so. He bent his way thither. The edge of the swamp was very clear, and, though somewhat spongy, afforded good walking unimpeded. As he approached the spot where he judged the boat to be, the underwood thickened, the trees again interlaced their arms, and he had to struggle through the foliage. At length he struck the smaller lagoon, and, as he was not certain whether it was fordable, he followed its course to the sh.o.r.e, where he had previously crossed. In a few moments he reached the boat, and was pleased to find her afloat. The rising tide had even moved her a few feet back into the ca.n.a.l.

Hazel shouted to apprise Miss Rolleston of his return, and then proceeded to restore the mast to its place, and replace the rigging and the oars.

This occupied some little time. He felt surprised that she had not appeared. He shouted again. No reply.

CHAPTER XXIX.

HAZEL advanced hurriedly into the grove, which he hunted thoroughly, but without effect. He satisfied himself that she could not have quitted the spot, since the marsh inclosed it on one side, the ca.n.a.ls on the second and third, the sea on the fourth. He returned to the boat more surprised than anxious. He waited awhile, and again shouted her name--stopped--listened--no answer.

Yet surely Helen could not have been more than a hundred yards from where he stood. His heart beat with a strange sense of apprehension. He heard nothing but the rustling of the foliage and the sop of the waves on the sh.o.r.e, as the tide crept up the shingle. As his eyes roved in every direction, he caught sight of something white near the foot of a withered cypress-tree, not fifty yards from where he stood. He approached the bushes in which the tree was partially concealed on that side, and quickly recognized a portion of Helen's dress. He ran toward her--burst through the underwood, and gained the inclosure. She was sitting there, asleep, as he conjectured, her back leaning against the trunk. He contemplated her thus for one moment, and then he advanced, about to awaken her; but was struck speechless. Her face was ashy pale, her eyes open and widely distended; her bosom heaved slowly. Hazel approached rapidly, and called to her.

Her eyes never moved, not a limb stirred. She sat glaring forward. On her lap was coiled a snake--gray, mottled with muddy green.

Hazel looked round and selected a branch of the dead tree, about three feet in length. Armed with this, he advanced slowly to the reptile. It was very quiet, thanks to the warmth of her lap. He pointed the stick at it; the vermin lifted its head, and its tail began to quiver; then it darted at the stick, throwing itself its entire length. Hazel retreated, the snake coiled again and again darted. By repeating this process four or five times, he enticed the creature away; and then, availing himself of a moment before it could recoil, he struck it a smart blow on the neck.

When Hazel turned to Miss Rolleston, he found her still fixed in the att.i.tude into which terror had transfixed her. The poor girl had remained motionless for an hour, under the terrible fascination of the reptile, comatized. He spoke to her, but a quick spasmodic action of her throat and a quivering of her hands alone responded. The sight of her suffering agonized him beyond expression, but he took her hands--he pressed them, for they were icy cold--he called piteously on her name. But she seemed incapable of effort. Then, stooping he raised her tenderly in his arms and carried her to the boat, where he laid her still unresisting and incapable.

With trembling limbs and weak hands he launched the cutter, and they were once more afloat and bound homeward.

He dipped the baler into the fresh water he had brought with him for their daily supply, and dashed it on her forehead. This he repeated until he perceived her breathing became less painful and more rapid. Then he raised her a little, and her head rested upon his arm. When they reached the entrance of the bay he was obliged to pa.s.s it, for, the wind being still southerly, he could not enter by the north gate, but came round and ran in by the western pa.s.sage, the same by which they had left the same morning.

Hazel bent over Helen, and whispered tenderly that they were at home. She answered by a sob. In half an hour the keel grated on the sand near the boat-house. Then he asked her if she were strong enough to reach her hut.

She raised her head, but she felt dizzy; he helped her to land; all power had forsaken her limbs; her head sank on his shoulder, and his arm, wound round her lithe figure, alone prevented her falling helplessly at his feet. Again he raised her in his arms and bore her to the hut. Here he laid her down on her bed, and stood for a moment beside her, unable to restrain his tears.

CHAPTER x.x.x.

IT was a wretched and anxious night for Hazel. He watched the hut, without the courage to approach it. That one moment of weakness which occurred to him on board the _Proserpine,_ when he had allowed Helen to perceive the nature of his feelings toward her, had rendered all his actions open to suspicion. He dared not exhibit toward her any sympathy--he might not extend to her the most ordinary civility. If she fell ill, if fever supervened! how could he nurse her, attend upon her?

His touch must have a significance, he knew that; for, as he bore her insensible form, he embraced rather than carried the precious burden.

Could he look upon her in her suffering without betraying his forbidden love? And then would not his attentions afflict more than console?

Chewing the cud of such bitter thoughts, he pa.s.sed the night without noticing the change which was taking place over the island. The sun rose; and this awakened him from his reverie, which had replaced sleep; he looked around, and then became sensible of the warnings in the air.

The sea-birds flew about vaguely and absurdly, and seemed sporting in currents of wind; yet there was but little wind down below. Presently clouds came flying over the sky, and blacker ma.s.ses gathered on the horizon. The sea changed color.

Hazel knew the weather was breaking. The wet season was at hand--the moment when fever, if such an invisible inhabitant there was on that island, would visit them. In a few hours the rain would be upon them, and he reproached himself with want of care in the construction of the hut.

For some hours he hovered around it, before he ventured to approach the door and call to Helen. He thought he heard her voice faintly, and he entered. She lay there as he had placed her. He knelt beside her, and was appalled at the change in her appearance.

The poor girl's system had received a shock for which it was unprepared.

Her severe sufferings at sea had, strange to say, reduced her in appearance less than could have been believed; for her physical endurance proved greater than that of the strong men around her. But the food which the island supplied was not suited to restore her strength, and the nervous shock to which she had been subjected was followed by complete prostration.

Hazel took her unresisting hand, which he would have given a world to press. He felt her pulse; it was weak, but slow. Her cheeks were hollow, her eyes sunken; her hand dropped helplessly when he released it.

Leaving the hut quietly, but hastily, he descended the hill to the rivulet, which he crossed. About half a mile above the boathouse the stream forked, one of its branches coming from the west, the other from the east. Between this latter branch and Terrapin Wood was a stony hill; to this spot Hazel went, and fell to gathering a handful of poppies. When he had obtained a sufficient quant.i.ty he returned to the boathouse, made a small fire of chips, and, filling his tin baler with water, he set down the poppies to boil. When the liquor was cool, he measured out a portion and drank it. In about twenty minutes his temples began to throb, a sensation which was rapidly followed by nausea.

It was midday before he recovered from the effects of his experiment sufficiently to take food. Then he waited for two hours, and felt much restored. He stole to the hut and looked in. Helen lay there as he had left her. He stooped over her; her eyes were half closed, and she turned them slowly upon him; her lips moved a little--that was all. He felt her pulse again; it was still weaker, and slower. He rose and went away, and, regaining the boat-house, he measured out a portion of the poppy liquor, one-third of the dose he had previously taken, and drank it. No headache or nausea succeeded; he felt his pulse; it became quick and violent; while a sense of numbness overcame him, and he slept. It was but for a few minutes. He awoke with a throbbing brow, and some sickness; but with a sense of delight at the heart, for he had found an opiate, and prescribed its quant.i.ty.

He drained the liquor away from the poppy leaves, and carried it to the hut. Measuring with great care a small quant.i.ty, he lifted the girl's head and placed it to her lips. She drank it mechanically. Then he watched beside her, until her breathing and her pulse changed in character. She slept. He turned aside then, and buried his face in his hands and prayed fervently for her life--prayed as we pray for the daily bread of the heart. He prayed and waited.

CHAPTER x.x.xI.

THE next morning, when Helen awoke, she was very weak; her head ached, but she was herself. Hazel had made a broth for her from the fleshy part of a turtle; this greatly revived her, and by midday she was able to sit up. Having seen that her wants were within her reach, he left her; but in a few moments she heard him busily engaged on the roof of her hut.
