SPRING

by William Blake


Sound the flute!
Now it's mute!
Birds delight,
Day and night,
Nightingale,
In the dale,
Lark in sky, -
Merrily,
Merrily, merrily to welcome in the year.

Little boy,
Full of joy;
Little girl,
Sweet and small;
Cock does crow,
So do you;
Merry voice,
Infant noise;
Merrily, merrily to welcome in the year.

Little lamb,
Here I am;
Come and lick
My white neck;
Let me pull
Your soft wool;
Let me kiss
Your soft face;
Merrily, merrily we welcome in the year.
