The tunnel to the Scotland Street Station, the sight of the trains shooting out of its dark maw with the two guards upon the brake, the thought of its length and the many ponderous edifices and open thoroughfares above, were certainly things of paramount impressiveness to a young mind.

It was a subterranean passage, although of a larger bore than we were accustomed to in Ainsworth's novels; and these two words, 'subterreanean passage,' were in themselves an irresistible attraction, and seemed to bring us nearer in spirit to the heroes we loved and the black rascals we secretly aspired to imitate.

To scale the Castle Rock from West Princes Street Gardens, and lay a triumphal hand against the rampart itself, was to taste a high order of romantic pleasure.

And there are other sights and exploits which crowd back upon my mind under a very strong illumination of remembered pleasure.

But the effect of not one of them all will compare with the discoverer's joy, and the sense of old Time and his slow changes on the face of this earth, with which I explored such corners as Cannonmills or Water Lane, or the nugget of cottages at Broughton Market.
