A small quantity of worked prehistoric flint was recovered from the 'Dub Field' at Bellellis by C.H. Cowley. No further details concerning the circumstances of the discovery are known. The antiquary Charles Harry Cowley was an avid collector of worked flint and coarse stone artefacts revealed by agricultural activity, mainly on farms located around Peel, and occasionally from further afield. He was active from 1900 until 1943. His entire collection of artefacts, together with a daybook cataloguing his discoveries, was later donated to Manx National Heritage.
