"The place, for all its decay and desolation, had not infected us with any touch of morbidity--that is not Edith, Stanton, or myself. But Thora was very unhappy. She was a Swede, as you know, and in her blood ran the beliefs and superstitions of the Northland--some of them so strangely akin to those of this far southern land; beliefs of spirits of mountain and forest and water werewolves and beings malign. From the first she showed a curious sensitivity to what, I suppose, may be called the 'influences' of the place. She said it 'smelled' of ghosts and warlocks. "I laughed at her then-- "Two weeks slipped by, and at their end the spokesman for our natives came to us. The next night was the full of the moon, he said. He reminded me of my promise. They would go back to their village in the morning; they would return after the third night, when the moon had begun to wane. They left us sundry charms for our 'protection,' and solemnly cautioned us to keep as far away as possible from Nan-Tauach during their absence. Half-exasperated, half-amused I watched them go. "No work could be done without them, of course, so we decided to spend the days of their absence junketing about the southern islets of the group. We marked down several spots for subsequent exploration, and on the morning of the third day set forth along the east face of the breakwater for our camp on Uschen-Tau, planning to have everything in readiness for the return of our men the next day. "We landed just before dusk, tired and ready for our cots. It was only a little after ten o'clock that Edith awakened me. "'Listen!' she said. 'Lean over with your ear close to the ground!' "I did so, and seemed to hear, far, far below, as though coming up from great distances, a faint chanting. It gathered strength, died down, ended; began, gathered volume, faded away into silence. "'It's the waves rolling on rocks somewhere,' I said. 'We're probably over some ledge of rock that carries the sound.' "'It's the first time I've heard it,' replied my wife doubtfully. We listened again. Then through the dim rhythms, deep beneath us, another sound came. It drifted across the lagoon that lay between us and Nan-Tauach in little tinkling waves. It was music--of a sort; I won't describe the strange effect it had upon me. You've felt it--" "You mean on the deck?" I asked. Throckmartin nodded. "I went to the flap of the tent," he continued, "and peered out. As I did so Stanton lifted his flap and walked out into the moonlight, looking over to the other islet and listening. I called to him. "'That's the queerest sound!' he said. He listened again. 'Crystalline! Like little notes of translucent glass. Like the bells of crystal on the sistrums of Isis at Dendarah Temple,' he added half-dreamily. We gazed intently at the island. Suddenly, on the sea-wall, moving slowly, rhythmically, we saw a little group of lights. Stanton laughed.
