Nor, even in these days of question and unbelief, is it matter of wonder that, at sight of the harmony of blended and mingling, yet always individual, and never confused colors, and notwithstanding his knowledge of optics, and of how the supreme unity of the light was secerned into its decreed chord, the imaginative faith of the troubled poet should so work in him as to lift his head for a moment above the waters of that other flood that threatened to overwhelm his microcosm, and the bow should seem to him a new promise, given to him then and individually, of the faithfulness of an unseen Power of whom he had been assured, by one whom he dared not doubt, that He numbered the very hairs of his head. Once more his spirit rose upon the wave of a hope which he could neither logically justify nor dare to refuse; for hope is hope whencesoever it spring, and needs no justification of its self-existence or of its sudden marvelous birth. The very hope was in itself enough for itself. And now he was near his home; his Annie was waiting for him; and in another instant his misery would be shared and comforted by her! He was walking toward the wonder-sign in the heavens. But even as he walked with it full in view, he saw it gradually fade and dissolve into the sky, until not a thread of its loveliness remained to show where it had spanned the infinite with its promise of good. And yet, was not the sky itself a better thing, and the promise of a yet greater good? He must walk onward yet, in tireless hope! And the resolve itself endured--or fading, revived, and came again, and ever yet again.
