Time passed. Minutes merged into quarters of hours, and quarters of hours into half-hours, and still the sound persisted, ever changing from its initial vocal impulse yet never receiving fresh impulse—fading, dimming, dying as enormously as it had sprung into being. It became a confusion of troubled mutterings and babblings and colossal whisperings. Slowly it withdrew, sob by sob, into whatever great bosom had birthed it, until it whimpered deadly whispers of wrath and as equally seductive whispers of delight, striving still to be heard, to convey some cosmic secret, some understanding of infinite import and value. It dwindled to a ghost of sound that had lost its menace and promise, and became a thing that pulsed on in the sick man’s consciousness for minutes after it had ceased. When he could hear it no longer, Bassett glanced at his watch. An hour had elapsed ere that archangel’s trump had subsided into tonal nothingness. Was this, then, _his_ dark tower?—Bassett pondered, remembering his Browning and gazing at his skeleton-like and fever-wasted hands. And the fancy made him smile—of Childe Roland bearing a slug-horn to his lips with an arm as feeble as his was. Was it months, or years, he asked himself, since he first heard that mysterious call on the beach at Ringmanu? To save himself he could not tell. The long sickness had been most long. In conscious count of time he knew of months, many of them; but he had no way of estimating the long intervals of delirium and stupor. And how fared Captain Bateman of the blackbirder _Nari_? he wondered; and had Captain Bateman’s drunken mate died of delirium tremens yet? From which vain speculations, Bassett turned idly to review all that had occurred since that day on the beach of Ringmanu when he first heard the sound and plunged into the jungle after it. Sagawa had protested. He could see him yet, his queer little monkeyish face eloquent with fear, his back burdened with specimen cases, in his hands Bassett’s butterfly net and naturalist’s shot-gun, as he quavered, in Bêche-de-mer English: “Me fella too much fright along bush. Bad fella boy, too much stop’m along bush.” Bassett smiled sadly at the recollection. The little New Hanover boy had been frightened, but had proved faithful, following him without hesitancy into the bush in the quest after the source of the wonderful sound. No fire-hollowed tree-trunk, that, throbbing war through the jungle depths, had been Bassett’s conclusion. Erroneous had been his next conclusion, namely, that the source or cause could not be more distant than an hour’s walk, and that he would easily be back by mid-afternoon to be picked up by the _Nari’s_ whale-boat.
