A local poem of Trentham by Annie Keary, “Fairy Men”, written when living in Trent Vale, Stoke-upon-Trent in the mid nineteenth century. In the second half she has “Cobbolds” = Kobold work-fairies, which I have looked into here in relation to Tolkien.

FAIRY MEN

In Trentham woods […] I spied the fairy men.

[Various very conventional fairy troops are seen passing by, for five verses]

Last the sad stooping cobbolds came,
  Through earth-holes small they creep;
With patient steps they struggle up
  The under ways so steep:
For sins they are condemned to work
  While other fairies sleep.

They carry tiny water-pails
  Upon their shoulders small,
Toilsomely in the under world
  Work they to fill them all:
Catching each raindrop as it drips
  Through their dark cavern wall.

All night through fields and lanes they go,
  And deftly as they run
They slip a dewdrop in each flower,
  On each grass-blade hang one,
Yet dare not wait to see them turned
  To diamonds by the sun.
