Edinburgh, before the sudden extension of its boundaries at the end of the eighteenth century, was thus a small, compact city, measuring in its proudest days but a mile in length and a half mile in width; but, though it was small, it was densely populated. Bounded in its growth by deep ravines and by a wall and a great loch--defences against the English--it extended itself in the only way it could, upwards towards the sky, whence it need fear “no enemy, but winter and rough weather.” Some of the highest houses in old Edinburgh were like vertical streets, with a spiral “common stair”; and they contained from floor to roof almost as many families as would a street in another town. The richer and better-born citizens lived in the most comfortable “flats,” and their poorer neighbours carried on their lives and their trades below them; by which means all ranks and sorts of persons were jostled together in a cosy, sociable “hugger-mugger” existence, quite incomprehensible to the modern citizen. The nobles of Scotland, before the Union drew them away to London, had their fine old town residences in Edinburgh--the “lands”[35] bearing their names. These were generally within closes, “obscurely founded in the aforesaid lanes,” as Taylor has it; but many were in the Cowgate, a fashionable suburb, or in the Canongate, which, being nearest Holyrood, was the court end of the city. It is down this “fairest and goodliest streete” that the tourist of to-day drives from the Castle to Holyrood, or up from Holyrood to the Castle. The driver will point with his whip at a gabled house standing forward into the street, and tell him it is John Knox’s house. At the Church of St. Giles he will probably stop the cab and descend, and, finding the door locked, will wander round the building and gaze down at the heart marked on the stones where once stood the Tolbooth, and at the initials I. K. where Knox is supposed to be buried, though another version has it that his grave is below the equestrian statue of Charles II. And so he will find himself in the precincts of Parliament House, built on ground which in past ages was the graveyard of the parish church. If he enter and have a glimpse of the great hall filled with lawyers in their wigs and gowns, strutting and fretting their hour as past generations did in their time, and as future generations will do in theirs, then he will probably let his mind rest upon Sir Walter Scott, the greatest of them all. And so his day in Edinburgh will leave him with a confused impression of a long squalid street full of draggled women and barefooted children, of groups of soldiers from the Castle, of carts and cries, of open “fore-stairs” and street wells, of ancient gabled roofs and of flapping garments hung out of windows on poles to dry, of pious legends and obliterated carvings, of an appalling number of drunken men, and of dark entries giving glimpses of tortuous obscurities, or leading steeply down some narrow
