And so wishing, Private Grayrock, overcome at last by the languor of the afternoon and lulled by the stilly sounds of insects droning and prosing in certain fragrant shrubs, so far forgot the interests of the United States as to fall asleep and expose himself to capture.  And sleeping he dreamed.

He thought himself a boy, living in a far, fair land by the border of a great river upon which the tall steamboats moved grandly up and down beneath their towering evolutions of black smoke, which announced them long before they had rounded the bends and marked their movements when miles out of sight.  With him always, at his side as he watched them, was one to whom he gave his heart and soul in love—­a twin brother.  Together they strolled along the banks of the stream; together explored the fields lying farther away from it, and gathered pungent mints and sticks of fragrant sassafras in the hills overlooking all—­beyond which lay the Realm of Conjecture, and from which, looking southward across the great river, they caught glimpses of the Enchanted Land.  Hand in hand and heart in heart they two, the only children of a widowed mother, walked in paths of light through valleys of peace, seeing new things under a new sun.  And through all the golden days floated one unceasing sound—­ the rich, thrilling melody of a mocking-bird in a cage by the cottage door.  It pervaded and possessed all the spiritual intervals of the dream, like a musical benediction.  The joyous bird was always in song; its infinitely various notes seemed to flow from its throat, effortless, in bubbles and rills at each heart-beat, like the waters of a pulsing spring.  That fresh, clear melody seemed, indeed, the spirit of the scene, the meaning and interpretation to sense of the mysteries of life and love.

But there came a time when the days of the dream grew dark with sorrow in a rain of tears.  The good mother was dead, the meadowside home by the great river was broken up, and the brothers were parted between two of their kinsmen.  William (the dreamer) went to live in a populous city in the Realm of Conjecture, and John, crossing the river into the Enchanted Land, was taken to a distant region whose people in their lives and ways were said to be strange and wicked.  To him, in the distribution of the dead mother’s estate, had fallen all that they deemed of value—­the mocking-bird.  They could be divided, but it could not, so it was carried away into the strange country, and the world of William knew it no more forever.  Yet still through the aftertime of his loneliness its song filled all the dream, and seemed always sounding in his ear and in his heart.

The kinsmen who had adopted the boys were enemies, holding no communication.  For a time letters full of boyish bravado and boastful narratives of the new and larger experience—­grotesque descriptions of their widening lives and the new worlds they had conquered—­passed between them; but these gradually became less frequent, and with William’s removal to another and greater city ceased altogether.  But ever through it all ran the song of the mocking-bird, and when the dreamer opened his eyes and stared through the vistas of the pine forest the cessation of its music first apprised him that he was awake.
