Alfred, Lord Tennyson - The Blackbird lyrics

The espaliers and the standards all Are thine; the range of lawn and park: The unnetted black-hearts ripen dark, All thine, against the garden wall. Yet, tho' I spared thee all the spring, Thy sole delight is, sitting still, With that gold dagger of thy bill To fret the summer jenneting. A golden bill! the silver tongue, Cold February loved, is dry: Plenty corrupts the melody That made thee famous once, when young: And in the sultry garden-squares, Now thy flute-notes are changed to coarse, I hear thee not at all, or hoarse As when a hawker hawks his wares. Take warning! he that will not sing While yon sun prospers in the blue, Shall sing for want, ere leaves are new, Caught in the frozen palms of Spring.
