The great line of east coast lying between the two headlands of Norfolk and Aberdeenshire is nowhere broken by another so bold and graceful indentation as that of the Firth of Forth. The Forth has its birth among hills that look down on Loch Katrine and Loch Lomond; flows thence in a pretty tortuous course towards the east, forming a boundary-line between the countries of the Gael and the Sassenach; is replenished by the Teith from the Trossachs and by the Allan from Strathmore; meanders at the foot of Stirling Castle, and seems never to weary of weaving its silver windings into that green expanse of country where most the Scottish imagination loves to linger; until at last, when there is poured into it the Devon from the Ochils, its channel widens to the sea somewhat suddenly. But even here the diverging banks, once so near, show an occasional friendly inclination to meet; and at one point there is only a mile of blue water and white waves between them, and then the view widens and the shores part irrevocably, the one stretching away to the extreme “east neuk” of Fife, and looking To Norroway, to Norroway, To Norroway ower the faem! and the other rolling with softer curves to the South and England, while the great German Ocean ebbs and flows between. The point where the banks of the Forth are but a mile apart is now spanned by that triumph of engineering, the Forth Bridge,--the largest bridge in the world; but in olden days there was here a famous crossing, and the names of the villages on the opposite banks, North Queensferry and South Queensferry, still carry the mind back to the days when Malcolm Canmore’s stately Saxon Queen, Saint Margaret of Scotland, was ferried across here on her way between the palace of Dunfermline and the Castle of Edinburgh. Edinburgh was not then, nor for centuries after, the Capital of Scotland, but merely a useful stronghold near the Borders,--a great rock rising abruptly among woods and lochs and hills, on which, from before the earliest legends of history, a fortress had stood,--an impregnable castle, built so long ago that none knows its origin, nor even the origin of its name. Stow’s _Chronicle_, indeed, dates the foundation of the “Castell of Maydens” 989 B.C., which is a sensational date to mention lightly to the inquiring tourist from the newer world. It is supposed that the name “Castell of Maydens” was gained because, in legendary days, certain Pictish princesses were kept there for safety; and certainly, from those hazy times right on till the time of Mary, Queen of Scots, when she was sent to the Castle for security before the birth of King James, Edinburgh Castle has always been a useful place of safety to which to send royalties and rebels. The earliest authentic romance of Edinburgh Castle is that of Malcolm Canmore and Queen Margaret; and the oldest building extant in Edinburgh is Queen Margaret’s chapel in the Castle.
