These are on the side of Cartington Hill. Tomlinson’s 1889 ‘Comprehensive Guide to the County of Northumberland’ says “About half-a-mile to the north*, on the left-hand side of a moorland road, are two large stones called “Priest” and “Clerk,” from their position, the one being a little below the other.” Derek Harper’s photos show them to be pretty weird looking.
*from what he calls ‘in the direction of Debdon House, a small Druid’s circle of nine large stones‘ – one of the cairns or something else?
