The globe we inhabit is divisible into two worlds; one hardly less tangible, and far more known than the other,--the common geographical world, and the world of books; and the latter may be as geographically set forth. A man of letters, conversant with poetry and romance, might draw out a very curious map, in which this world of books should be delineated and filled up, to the delight of all genuine readers, as truly as that in Guthrie or Pinkerton. To give a specimen, and begin with Scotland,--Scotland would not be the mere territory it is, with a scale of so many miles to a degree, and such and such a population. Who (except a patriot or cosmopolite) cares for the miles or the men, or knows that they exist, in any degree of consciousness with which he cares for the never-dying population of books? How many generations of men have passed away, and will pass, in Ayrshire or Dumfries, and not all the myriads be as interesting to us as a single Burns? What have we known of them, or shall ever know, whether lairds, lords, or ladies, in comparison with the inspired ploughman? But we know of the bards and the lasses, and the places which he has recorded in song; we know the scene of 'Tam o' Shanter's' exploit; we know the pastoral landscapes ... and the scenes immortalized in Walter Scott and the old ballads; and, therefore, the book-map of Scotland would present us with the most prominent of these. We should have the Border, with its banditti, towns, and woods; Tweedside, Melrose, and Roslin, 'Edina,' otherwise called Edinburgh and Auld Reekie, or the town of Hume, Robertson, and others; Woodhouselee, and other classical and haunted places; the bower built by the fair hands of 'Bessie Bell' and 'Mary Gray'; the farm-houses of Burns's friends; the scenes of his loves and sorrows; the land of 'Old Mortality', of the 'Gentle Shepherd', and of 'Ossian'. The Highlands, and the great blue billowy domains of heather, would be distinctly marked out, in their most poetical regions; and we should have the tracks of Ben Jonson to Hawthornden, of 'Rob Roy' to his hiding-places, and of 'Jeanie Deans' towards England. Abbotsford, be sure, would not be left out; nor the house of the 'Antiquary'--almost as real a man as his author. Nor is this all: for we should have older Scotland, the Scotland of James the First, and of 'Peeblis at the Play', and Gawin Douglas, and Bruce, and Wallace; we should have older Scotland still, the Scotland of Ariosto, with his tale of 'Ginevra', and the new 'Andromeda', delivered from the sea-monster at the Isle of Ebuda (the Hebrides); and there would be the residence of the famous 'Launcelot of the Lake', at Berwick, called the Joyeuse Garde, and other ancient sites of chivalry and romance; nor should the nightingale be left out in 'Ginevra's' bower, for Ariosto has put it there, and there, accordingly, it is and has been heard, let ornithology say what it will; for what
