Possibly "scratching post " , it might also explain a lot of what became " stones " in the name books .Often found in local clusters , the give away is that they are in the middle of a field and hence have no relationship to boundaries like gates , dykes etc .

Glad everyone are finding the maps useful though I don't know the answer to the post question - old roads, drove roads etc.... I used to use OS Oldmaps UK, which were not very good, these maps with the grid referencing are better.

Though pinpointing is difficult, still trying to get locations on Bodmin Moor, as we are also off to Cornwall beginning of April. For instance just to take King Arthur's Hall, it has a trackway by it, and a stone base by the track, presumably for an early stone cross. But what really interests me are the settlements on the moors, (there is one just under the ridge by KAH) and it would be interesting to see how they are marked on older maps.....
