Go, for they call you, Shepherd, from the hill;
Go, Shepherd, and untie the wattled cotes:
No longer leave thy wistful flock unfed,
Nor let thy bawling fellows rack their throats,
Nor the cropp'd grasses shoot another head.
But when the fields are still,
And the tired men and dogs all gone to rest,
And only the white sheep are sometimes seen
Cross and recross the strips of moon-blanch'd green;
Come Shepherd, and again begin the quest.
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night.
