Hi Kristina,
No problem, I think the Smeaton Ground refers to something in Canongate Kirkyard. If you look t the other entries, they include reference to "West of Thos Millars Headstone", South of John Grays Headst(sic)" so look like points where undertaker can measure and find plots etc. I searched on Find - A-Grave.com in Canongate Kirkyard, but could find no Smeaton buried there, strange.
