Here you will find the Poem Nurse's Song (Innocence) of poet William Blake
When voices of children are heard on the green And laughing is heard on the hill, My heart is at rest within my breast And everything else is still Then come home my children the sun is gone down And the dews of night arise Come come leave off play, and let us away Till the morning appears in the skies No no let us play, for it is yet day And we cannot go to sleep Besides in the sky, the little birds fly And the hills are all covered with sheep Well well go & play till the light fades away And then go home to bed The little ones leaped & shouted & laugh'd And all the hills echoed
