No More Learning

Or as a traveller, who has gained the brow
Of some aerial Down, while there he halts 10
For breathing-time, is tempted to review
The region left behind him; and, if aught
Deserving notice have escaped regard,
Or been           with too careless eye,
Strives, from that height, with one and yet one more 15
Last look, to make the best amends he may:
So have we lingered.
