But these they have for ever — ever left;
And soon the forest's verdant roof grows dun
Upon the distant eye. The eager
With spur and slacken'd reins, kept pouring on,
Leaving whole leagues obscur'd with floating dust.
The royal Prisoners, scarcely with a glance,
Can speak a thought, much less converse, and share,
With kind participance, each other's woe.
