The thought was enough to make the stoutest shudder, and feeling now that his safety lay in movement, he took a few more steps towards the vapour, finding himself, before he was aware of the fact, and without the slightest mistiness being visible, within its influence.
He started away in alarm, for he was suffering from a slight attack of vertigo, which did not pass off for a minute or two, and he walked, or rather staggered, back, with the tough elastic film over which he walked now rising and falling with an undulatory motion beneath his feet.
“Only as a last resource,” he muttered, as he breathed freely once more; and he could not repress a shudder as he stepped once more on solid ground, plainly enough marked by the abounding growth, and grasping fully how horrible a quagmire of hot slime was hidden by the partially hardened crust over which he had passed.
Turning his face now toward the mountain, he hesitated for a few moments, and then determined, as the distance seemed so short, to try and do something now he was there; and in the intent of climbing a few hundred feet up its side so as to get a view beyond, he marked out what seemed to be the most open way, and started for the foot of the great slope.

It required no little steady determination to attack that ascent. Oliver’s nerves had been terribly shaken by that which he had gone through. The heat was intense beneath the trees, where hardly a breath of air reached him, and it was impossible to keep off the sense of loneliness and awe brought on by the knowledge that he was in the home of Nature’s most terrible forces, and that the huge mountain in front, now looking so calm and majestic, might at any moment begin to belch forth showers of white-hot stones and glowing scoria, as it poured rivers of liquid lava down its sides. At any moment too he knew that he might step into some bottomless rift, or be overcome by gases, without calculating such minor chances as losing his way in the pathless wilderness through which he was struggling, or coming in contact with some dangerous beast.
But he set his teeth and toiled on, dragging thorny creepers aside, climbing over half-rotten tree-trunks, whose mouldering bark gave way, and set at liberty myriads of virulent ants. Once or twice he grasped leaves which were worse than the home-growing nettle. But he struggled on, though, with the feeling growing stronger, that if he got through the patch of forest before dark, it would be as much as he could manage, for the difficulties increased at every step.
