It ran through strange and secret places where the soft mists hung in wet wreaths. I seemed to be in another world when I was in its lair. On the sharply rising banks stood the sentinel trees like shadows, some of them with tortured and tormented shapes. As I turned and looked straight up the hill of the burn's descending course, the mountain from which it came closed in the prospect inexorably. A soft gloom hemmed us in--me and the burn which talked to me. We two were out of the world which I hated and longed to have at my feet. Yes, we were in another world, full of murmuring and of restful unrest; and now that I was right down at the water-side, the ivory face of my friend, the ivory lips that spoke to me, the ivory heart that beat against my heart--so sick and so weary--were varied and were changed. As thoughts streak a mind, the clear amber of the pools among the rocks streaked the continuous foam that marked the incessant leaps taken by the water towards the valley. The silence of those pools was brilliant, like the pauses for contemplation in a great career of action; and their silence spoke to me, mingling mysteriously with the voice of the foam. The course of the burn is broken up, and attended by rocks that have been modelled by the action of the running water into a hundred shapes. Some are dressed in mosses, yellow and green, like velvet to the touch, and all covered with drops of moisture; some are gaunt and naked and deplorable, with sharp edges and dry faces. The burn avoids some with a cunning and almost coquettish grace, dashes brutally against others, as if impelled by an internal violence of emotion. Others, again, it caresses quite gently, and would be glad to linger by, if Nature would allow the dalliance. And this army of rocks helps to give to the burn its charm of infinite variety, and to fill its voice with a whole gamut of expression; for the differing shape of each boulder, against which it rushes in its long career, gives it a different note. It flickers across the small and round stone with the purling cry of a child. From the stone curved inwards, and with a hollow bosom it gains a crooning, liquid melody. The pointed and narrow colony of rocks which break it into an intricate network of small water threads, toss it, chattering frivolously, towards the dark pool under the birches, where the trout play like sinister shadows and the insects dance in the sombre pomp of Autumn; and when it gains a great slab that serves it for a spring-board, from which it takes a mighty leap, its voice is loud and defiant, and shrieks with a banshee of triumph--in which, too, there is surely an undercurrent of wailing woe. Oh, the burn has many voices among the rocks, under the ferns and the birch trees, in the brooding darkness of the mists and shadows, between the steep walls of the green banks that hem it in! Many voices which can sing, when they choose, one song, again and again and--monotonously--again!
