Excerpt: "On the evening of the 22nd November, 1440, the report of a brass carthoun, or cannon-royale, as it pealed from the castle of Edinburgh, made all who were in the thoroughfares below raise their eyes to the grey ramparts, where the white smoke was seen floating away from the summit of King David's Tower, and then people were seen hastening towards the southern side of the city, where the quaint old streets and narrow alleys opened into the fields, or the oakwoods of Bristo and Drumsheugh."
