To leave home in early life is to be stunned and quickened with novelties; but to leave it when years have come only casts a more endearing light upon the past. As in those composite photographs of Mr. Galton's, the image of each new sitter brings out but the more clearly the central features of the race; when once youth has flown, each new impression only deepens the sense of nationality and the desire of native places. So may some cadet of Royal Ecossais or the Albany Regiment, as he mounted guard about French citadels, so may some officer marching his company of the Scots-Dutch among the polders, have felt the soft rains of the Hebrides upon his brow, or started in the ranks at the remembered aroma of peat-smoke. And the rivers of home are dear in particular to all men. This is as old as Naaman, who was jealous for Abana and Pharpar; it is confined to no race nor country, for I know one of Scottish blood but a child of Suffolk, whose fancy still lingers about the lilied lowland waters of that shire. But the streams of Scotland are incomparable in themselves--or I am only the more Scottish to suppose so--and their sound and colour dwell for ever in the memory. How often and willingly do I not look again in fancy on Tummel, or Manor, or the talking Airdle, or Dee swirling in its Lynn; on the bright burn of Kinnaird, or the golden burn that pours and sulks in the den behind Kingussie! I think shame to leave out one of these enchantresses, but the list would grow too long if I remembered all; only I may not forget Allan Water, nor birch-wetting Rogie, nor yet Almond; nor, for all its pollutions, that Water of Leith of the many and well-named mills--Bell's Mills, and Canon Mills, and Silver Mills; nor Redford Burn of pleasant memories; nor yet, for all its smallness, that nameless trickle that springs in the green bosom of Allermuir, and is fed from Halkerside with a perennial teacupful, and threads the moss under the Shearer's Knowe, and makes one pool there, overhung by a rock, where I loved to sit and make bad verses, and is then kidnapped in its infancy by subterranean pipes for the service of the sea-beholding city in the plain. From many points in the moss you may see at one glance its whole course and that of all its tributaries; the geographer of this Lilliput may visit all its corners without sitting down, and not yet begin to be breathed; Shearer's Knowe and Halkerside are but names of adjacent cantons on a single shoulder of a hill, as names are squandered (it would seem to the inexpert, in superfluity) upon these upland sheepwalks; a bucket would receive the whole discharge of the toy river; it would take it an appreciable time to fill your morning bath; for the most part, besides, it soaks unseen through the moss; and yet for the sake of auld lang syne, and the figure of a certain _genius loci_, I am condemned to linger awhile in fancy by its shores; and if the nymph (who
