During the voyage Martin had listened to many discussions between Little Billy and Captain Dabney concerning the formation of Fire Mountain, and their descriptions of the strange features of the island had made him impatient to see with his own eyes the grotesque sculptures, and with his own feet explore the mysterious caverns.
In some long past age, argued the captain, the volcano had erupted during the Arctic winter, and the flowing lava had been quickly chilled by the intense cold, and in the hardening formed the odd sculpting and the numberless caves. But, urged the captain, this lava cloak could not be very thick, and while the caves existed from base to summit and all the way around the mountain, it was unlikely that any of them penetrated into the heart of the mountain.
Little Billy disagreed. He cited John Winters's log in disproof; and he and Martin made plans to thoroughly explore the Island. The prospect charmed Martin. He felt he could hardly wait to reach Fire Mountain beach, and enter the gloomy depths through the portal of the Elephant Head on his errand of discovery.
And here at last he was on the very beach, stepping through the very opening! How different was reality from his bright dreams? Instead of friendly company, he was surrounded by alien, hostile figures; instead of Ruth's little hand snuggling confidingly in his, his arms were bound behind him; instead of inspecting his path with carefree, curious gaze, he looked about him with eyes of desperation.
He had little interest in discovery as he stepped through the Elephant Head. The details of the physical appearance of the passageway were sharply impressed upon his mind, but they were subconscious impressions. His active mind was at the moment wholly concerned with his arms. They ached cruelly. Would they fail him? When he jerked them free, would he be able to use them? Or would they drop numb and useless by his sides? No, he decided after cautious experiment, they were not numbed. He could wriggle his fingers easily.
Ichi walked first, then Martin, the grim Moto next, and the four sailors trailed behind, the last man carrying the second lantern. The gallery they traversed was a deep fissure in the black rock, of uneven height and width. The walls narrowed until they could hardly squeeze through, and then widened until the lanterns' rays failed to reveal them; at times Martin had to bend his head to pass beneath the low roof; again the roof was lost in the gloom.
After a few steps, the sand underfoot gave place abruptly to a floor of hard, smooth lava rock. The gallery twisted, and the thin shaft of daylight from the entrance was lost. The way sloped gently upward. The lanterns waged but a feeble battle against the darkness; Martin felt he was being crushed by that heavy, intense gloom. Their steps echoed upon the glasslike, slippery rock underfoot.
Soon Martin was sensible of a sharp rise in temperature. There was a strong draft in the passageway, and a hot, smelly air blew against his face, and ruffled his hair. And now he was also conscious of the low moaning, a vast, spine-prickling moaning like the protest of a giant in pain, that came out of the darkness ahead.
They wound this way and that. Martin had lost count of the steps, but he thought they must have gone sixty or seventy yards into the mountain. They passed an opening, but it was on the left hand.
The whaleman's directions were in Martin's mind: "4 starboard—windy cave." That must mean the fourth opening on the right hand. The cave of winds. Ichi said that was where the "deep place" was located. This horrible moaning must come from there. Ichi's "deep place" must be Winters's "bottomless hole"; the weird moaning must be the "Voice" that called the conscience-stricken Silva to his doom.
