" She realized that a child's mind is like a shallow brook which ripples and dances merrily over the stony course of its education and reflects here a flower, there a bush, yonder a fleecy cloud; and she attempted to guide my mind on its way, knowing that like a brook it should be fed by mountain streams and hidden springs until it broadened out into a deep river, capable of reflecting in its placid surface, billowy hills, the luminous shadows of trees and the blue heavens, as well as the sweet face of a little flower.
