- a gullion is a term for a quagmire, marsh or swamp, as described in the following quotation from John MacTaggart's Scottish Gallovidian Encyclopedia (1824):
He'd slonk adown, or ere he ken'd,
A miry, quacking quaw,
Or glauroch, far aboon the knee,
Through some blue rashy gullion.
A gullion can also be a pool of soft mud, manure, decayed vegetable matter or any mushy substance, especially one found on farmland. In Matthew Mulcaghey's Ballymulcaghey (1929) there is a typical illustration:
Down he went on the whole broad of his back in yon gullion at the byre dure.
