The woman had noticed neither the man nor her protector because she was far, far, away in her Yesterdays. She did not heed the incident because she was a little girl again, playing beside the brook that came across the road and made its winding way through the field just below the house. It was only a little brook, but beautifully clear and fresh, for it had come only a short distance from its birth place in a glen under the hill that she could see from her window. In some places, the long meadow grass, growing close down to the edge, almost touched above, making a cool, green, cradle arch through which the pure waters flowed with soft whispers as though the baby stream were crooning to itself a lullaby. In other stretches, the green willows bent far over to dip their long, slim, fingers in the slow current that crept so lazily through the flickering light and shade that it seemed scarce to move at all. And other places there were, where the streamlet chuckled and laughed over tiny pebbly bars in the sunlight or gurgled past where flags and rushes grew.

Again, with her dolls, the little girl played on the grassy bank; washing their tiny garments in the clear water and hanging them on the flags or willows to dry; resting often to listen to the fairy song the water sang; or to whisper to the brook the secrets of her childhood dreams. The drowsy air was full of the sweet, grassy, smell mingled with the odor of mint and the perfume of the willows and flags and warm moist earth. Gorgeous winged butterflies zigzagged here and there from flower to flower—now near for a little—then far away. Honeybees droned their hymns of industry the while they searched for sweet treasures. And now and then a tiny green frog would come out of a shadowy nook in the bank of the stream to see what the little girl was doing; or a bird would drop from out the blue sky for a drink or a bath in the pebbly shallows. And not far away—easily within call—mother sat on the shady porch, with her sewing, where she could watch over her little girl.

Dear, innocent, sheltered, protected, Yesterdays—when mother told her child all that was needful for her to know, and told her in a most tender, beautiful, way. Dear, blessed, Yesterdays—when love did not leave vice to teach the sacred truths of love—days that were days of blissful Ignorance—not vicious Ignorance but ignorance of the vicious. There was a wealth of Ignorance in those Yesterdays that is of more worth to womanhood, by far, than much knowledge of the world.

And often the boy would come, too, and, together, they would wade hand in hand in the clear flood, mingling their shouts and laughter with the music of their playmate brook, while the minnows darted to and fro about their bare legs; or, they would build brave dams and bridges and harbors with the bright stones; or, best of all, fashion and launch the ships of childhood.

Oh, childish ships of the Yesterdays! What precious cargoes they carried! What priceless treasures they bore to the far away port of dreams!

The little brook was a safe stream for the boy and the girl to play beside. Nor did they know, then, that their streamlet flowed on and on until it joined the river; and that the river, in its course, led it past great cities that poured into it the poisons and the filth of their sewers, fouling its bright waters, until it was unfit for children to play beside.

They did not know, then—but the woman knew, now.

And what—she thought as she came back from her Yesterdays—what of the boy who had played with her beside the brook? He, too, must have learned what happened to their brook. In learning, what had happened to him—she wondered—and wondering, she was afraid.

Because she was no longer ignorant, she was afraid for the mate of her Yesterdays. Not that she thought over to meet him again. She did not wish, now, to meet him for she was afraid. She would rather have him as he was in her Yesterdays.

Slowly the woman turned away from the quiet seat beside the brook. It was time for her to go.
