Ogham is an early medieval script, typically cut as a series of notches and grooves along the edge or face of a stone, and used primarily to record personal names in an archaic form of Irish. The Sallagher example, if that is what it is, belongs to a category that is harder to study than most: the kind that has simply disappeared.

The stone first came to official attention when it was notified to the National Museum of Ireland in the 1950s. Whoever reported it included a sketch and a map indicating its location. The sketch depicts an upright, earthfast stone, roughly triangular in profile, with grooves or scores cut at and across one of its angles. Ten scores in total are shown, arranged in four separate groups of two or three. That grouping is consistent with how ogham characters work, each letter being formed by a specific number of strokes relative to a central stemline, though without dimensions or a full inscription it is impossible to read any meaning into what was recorded. When the site was visited in 1997, nothing was visible. Local knowledge offered an explanation: the stone had been buried, deliberately or incidentally, during the construction of a house in the early 1980s.
