The captives found it difficult to sleep in the confined air of the cave, which grew more hot and stifling as the fire died out. Occasionally fatigue overpowered them and they dozed; but they were oftener awake, from a restlessness they could not account for, and which kept their senses in that dreamy, vague condition, which neither admits of perfect consciousness nor salutary rest. At intervals a hoarse blast, and a dull heavy roar, like the sudden escape of vast volumes of ignited gases, startled their ears. Several times the cave trembled as if in an ague fit; once so violently that a loosened rock fell near the guards and caused them all to start up. For a few seconds they staggered like sea-sick men, but recognizing the breathings of the volcano, with which they were familiar, they merely ejaculated, “Pele is sporting to-night in the fire-surf,” and laid themselves down again to sleep.
At the earliest light all were on foot for a fresh start. The rain had ceased, but the atmosphere was lurid and heavy, and respiration more or less difficult. They found themselves upon a knoll of considerable dimensions, lightly wooded, and surrounded by a sea of lava, over which they could not see far on account of the smoke and steam arising from it in all directions. During the night a fresh flow had spread itself over the clinkers they had passed the day before. It was now so hot and vaporous as to cut off all retreat in that direction.
As the wind at times dispersed the smoke, they caught glimpses of the fountain-head of the stream, apparently some fifteen miles from them, and about half way up the mountain. It was not a violent eruption, but poured out at short intervals, with roarings and tremblings of the earth, huge masses of molten rock of the hue of blood, which descended rapidly towards them. In spots it suddenly disappeared, emerging at some distance, and continuing its course with renewed rapidity. This was caused by its meeting with an obstacle it had not sufficient volume to overwhelm, but was driven to eat its way underground, forming galleries, which, when cooled and emptied of the lava, leave caves sometimes of great extent and intricacy. This alternate appearing and disappearing of the crimson fluid amid the surrounding blackness, gave it the look of the glaring eyes of huge basilisks watching in desert caverns for their prey. At times it leaped precipices with a furious, fiery plunge, scattering its hot spray on all sides, rock and forest alike recoiling from its destructive touch, shivering into a thousand fragments, or melting with the fervent heat, and swelling the consuming tide.
The progress of the torrent towards them was so rapid, as to leave but little time for reflection. It was gradually rising all around, and threatened to submerge the knoll, which as yet had escaped. Many of the trees on its skirts had already been crisped and blackened with the heat; some had fallen, the trunks being burned off near the ground, while the branches lay unconsumed, on the lava stream, which cools and hardens very rapidly, presenting a surface often sufficiently strong to bear a man’s weight, even while the crimson current is flowing underneath. This fact was suggested to Tolta by his men as the most likely means of escape. Indeed none other seemed to offer.
Accordingly, they sought the stream in the direction in which it was narrowest and firmest. Ten of the warriors spread themselves out in the form of a fan, sounding their way with their spears as if on ice, for fear of air-holes, and to test the strength of its surface. The remainder of the party followed, more or less apart, with great caution, holding their breaths to lighten their weights. Their feet were protected by rough sandals, and bits of wood strapped to them, from the lava, which was in spots still so warm as frequently to raise blisters. Where it had suddenly cooled it had split up into deep chasms, raised cones, and twisted and cracked into every variety of shape. It was therefore with the greatest difficulty that any progress could be made. They persevered, however, when a sudden crack was heard, and at the same instant a shriek of agony. The foremost of the warriors had trodden upon the thin crust where it had been puffed up by the air, and, being as brittle as glass, it had broken and let him down into the liquid lava beneath.
Appalled by his fate, the whole party halted. To go on was impossible, as it was evident they had reached the extreme verge of solid lava. All beyond was either fluid, or so densely covered with sulphurous vapor, that it was sure death to advance. They retraced their steps without a minute’s delay, and it was none too soon. A fresh wave of lava was fast descending towards them, and setting the crust on which they were all in motion. Suddenly a vein of red lava showed itself in a narrow chasm, over which several of the warriors had already leaped. At the same moment, detonating gases were heard near by, and then louder explosions, from which the air was fast becoming impregnated with deadly vapors. Beatriz, sinking from their suffocating effects, faintly said to Olmedo, “My father, I can go no farther,—my strength is all gone.”
He had been sustaining her for some time past, and felt himself scarcely stronger, but roused by her danger he seized her in his arms and was about to leap the fiery chasm, when he stumbled and partially fell, with both their weights overhanging its brink. Quicker than thought the men nearest seized them, and, before a word could be uttered, by a violent effort they had cleared the chasm, but not before all were slightly scorched by the heat which flickered above it. They had scarcely time to leave the spot before it discharged a stream of viscid lava, which pursued them coiling and twisting after their footsteps like a wounded snake. As it was an easy matter to outrun this, they soon got back to the knoll, which now rose like an island above the molten flood.
The Hawaiians, breathless with their efforts, sat down and gazed hopelessly upon the rising lava. A dense poisonous smoke was gradually narrowing their horizon all around and slowly approaching, leaving no hope of escaping suffocation, even if they were spared a more immediate and violent death. Their position was far worse than to be on a burning prairie, for fire can then be made to fight fire as the ally of man. Here all nature was melting before the heat of the eruption. At any instant the solid rock on which they sat might surge and toss like the waves of the ocean, in blazing, gory-hued billows, while of themselves not one particle of matter would survive to disclose their fate. The fast increasing heat soon drove them to the centre of the hill, where sheltered by a pile of stones they had a moment’s respite.
