Analysis of Emmonsail's Heath in Winter

I love to see the old heath's withered brake
Mingle its crimpled leaves with furze and ling,
While the old heron from the lonely lake
Starts slow and flaps its melancholy wing,
An oddling crow in idle motion swing
On the half-rotten ash-tree's topmost twig,
Beside whose trunk the gypsy makes his bed.
Up flies the bouncing woodcock from the brig
Where a black quagmire quakes beneath the tread;
The fieldfares chatter in the whistling thorn
And for the haw round fields and closen rove,
And coy bumbarrels, twenty in a drove,
Flit down the hedgerows in the frozen plain
And hang on little twigs and start again.
