Till he came where the dwarfs stood hammering steel,
By the light of a furnace blue.
I trow ’t was a goodly sight to see
The dwarfs, with their aprons on,
A-hammering and smelting so busily
Pure gold from the rough brown stone.
Rock crystals from sand and hard flint they made,
Which, tinged with the rosebud’s dye,
They cast into rubies and carbuncles red,
And hid them in cracks hard by.
