All these facts prove that the old wall which enclosed Kirk o’ Field and the Black Friars on the south had fallen into disrepair, and that new walls had for some time before the murder been in course of building. Now, in the map of 1647, we find a very neat and regular wall, to the south of the site that had been occupied by Kirk o’ Field. Whereas, in Darnley’s time, there had been a gate called Kirk o’ Field Port to the left, or west, of the Kirk o’ Field, by 1647 there was no such name, but, instead, Potter Row Port, to the left, or west, of the University buildings; by 1647 these included Hamilton House, and the ground covered by Kirk o’ Field. This wall, extant in 1647, I take to be ‘the new wall,’ passing lineally ‘to the wall of the church yard’ of Kirk o’ Field. It supplied the place of the wall which, in the chart of 1567 (p. 130), ran south and north past the gable of Kirk o’ Field. Thus Kirk o’ Field, in February, 1567, had, to the south of it, an old decayed town wall, much fallen down, and was thus _within_ that town wall. But ‘it is traditionally said,’ writes the editor of Keith, Mr. Parker Lawson, in 1845, ‘that the house of the Provost of Kirk o’ Field’ (in which house, or the one next to it, Darnley was blown up) ‘stood as near as possible _without_ the then city walls.’[125] Scott follows this opinion in ‘The Abbot.’ Yet certainly Kirk o’ Field was not without, but within, the ruinous town wall mentioned in the Burgh Records of May 7, 1567. How are we to understand this discrepancy?
