And deepen slumber in the shut blue eyes,
And the shrill cadences of her high singing
Are to the babe but wonted lullabies.

For a bobolink, or a yellow bird,

Or sleep in a round coil half the day;
While, creakety-creak, the rockers go,
And the mittens grow, and grow, and grow,
So shapely and fast--
They are done at last!
