Next, impelled by that driving sense of duty to Skale, he turned to the girl at his side:  “Can you do it?” he cried.

Unable to make her voice heard above the clamor she nodded quickly in acquiescence.  Spinrobin noticed that her little mouth was set rather firmly, though there was a radiance about her eyes and features that made her sweetly beautiful.  He remembers that her loveliness and her pluck uplifted him above all former littlenesses of hesitation; and, seizing her outstretched hand, they flew up the main staircase and in less than a minute reached the opening of the long corridor where the rooms were.

Here, however, they stopped with a gasp, for a hurricane of moving air met them in the face like the draught from some immense furnace.  Again the crest of a wave in the colossal sound-vibration had caught them.  Staggering against the wall, they tried again and again to face the tempest of sound and light, but the space beyond them was lit with the same unearthly brilliance as the hall, and out of the whole long throat of that haunted corridor issued such a passion of music and such a torrent of gorgeous color, that it seemed impossible for any aggregation of physical particles—­least of all poor human bodies—­to remain coherent for a single instant before the concentrated onslaught.

Yet, game to the inmost core of his little personality, and raised far above his normal powers by the evidence of Miriam’s courage and fidelity, he struggled with all his might and searched through the chambers of his being for the note he was ordained to utter in the chord.  The ignominy of failure, now that the great experiment was full upon him—­failure in Miriam’s eyes, too—­was simply impossible to contemplate.  Yet, in spite of every effort, the memory of that all-important note escaped him utterly, for the forces of his soul floundered, helpless and disheveled, before the too mighty splendors that were upon him at such close quarters.  The sounds he actually succeeded in emitting between dry and quivering lips were pitiful and feeble beyond words.

Down that living corridor, meanwhile, he saw the doors of the four rooms were gone, consumed like tissue paper; and through the narrow portals there shouldered forward, bathed in light ineffable, the separate outlines of the Letters so long imprisoned in inactivity.  And with their appearance the sounds instantly ceased, having overpassed the limits of what is audible to human ears.  A great stillness dropped about them with an abrupt crash of utter silence.  For a “crash” of silence it was—­all-shattering.

And then, from the categories of the incomprehensible and unmanifest, “something” loomed forth towards them where, limp and shaking, they leaned against the wall, and they witnessed the indescribable operation by which the four Letters, whirling and alive, ran together and melted into a single terrific semblance of a FORM ... the sight of which entered the heart of Spinrobin and threatened to split it asunder with the joy of the most sublime terror and adoration a human soul has ever known.
