For this _infelix campus_, as it is dubbed in one of its own inscriptions--an inscription over which Dr. Johnson passed a critical eye--is in many ways sacred to the memory of the men whom Mackenzie persecuted. It was here, on the flat tombstones, that the Covenant was signed by an enthusiastic people. In the long arm of the churchyard that extends to Lauriston, the prisoners from Bothwell Bridge--fed on bread and water, and guarded, life for life, by vigilant marksmen--lay five months looking for the scaffold or the plantations. And while the good work was going forward in the Grassmarket, idlers in Greyfriars might have heard the throb of the military drums that drowned the voices of the martyrs. Nor is this all: for down in the corner farthest from Sir George, there stands a monument, dedicated, in uncouth Covenanting verse, to all who lost their lives in that contention. There is no moorsman shot in a snow shower beside Irongray or Co'monell; there is not one of the two hundred who were drowned off the Orkneys; nor so much as a poor, over-driven, Covenanting slave in the American plantations; but can lay claim to a share in that memorial, and, if such things interest just men among the shades, can boast he has a monument on earth as well as Julius Caesar or the Pharaohs. Where they may all lie, I know not. Far-scattered bones, indeed!

Some of the insane controversial matter I omit, as well as some digressions, but leave the rest in Patrick Walker's language and orthography:--
