Would that one could say the same with regard to the effect of their dyes and refuse on the condition of the river. By a steep red "scaur" below Linglie there once was a pool clearer than amber, across which in summer weather small boys, breathless but greatly daring, essayed to swim. Farther down, at the back of Lindean Flour Mill, was another, where in the long twilights of June, ". . trout beneath the blossom'd tree, Plashed in the golden stream," and whence many a pounder and half-pounder was drawn by eager young fishers. Where is that seductive amber-clear water now? Alas! in these days it is of a sickly blue tint, smelling evilly; and the stones in its bed, that once were a clear, warm grey, with yellow boulders interspersed that flashed in the stream of a sunny day like burnished copper,--they are slime-covered and loathsome, things to be shunned. Surely more can be done to check this pollution of our beautiful streams. So far as can be ascertained, there is but one of the mills of Selkirk that strives (and I believe it strives successfully,) so to deal with its refuse that the water it uses may be returned to Ettrick in a condition that does not defile that stream. {253}Nevertheless, it has to be admitted that during the autumn floods salmon do run the gauntlet of Ettrick's lower reaches, and in countless numbers congregate below Selkirk Cauld (or weir), where the difficulty of ascent acts as a partial check on their continued migration. On a day in the month of November, if there should happen to be a considerable flood in the river, this cauld is a sight worth going a long way to look at. A wide rushing sea of tawny, foaming water--a hundred yards from bank to bank--races over the sloping face of the cauld, and, where it plunges into the deep pool at foot, rears itself in a mighty wave, with crest that tosses in the wintry breeze "like the mane of a chestnut steed." From daylight till dark you may watch the fish,--big and little, from the thirty-pound leviathan to the little one or two-pound sea trout--in their eagerness to reach the spawning-beds of the upper waters, hurl themselves high in air over this great barrier-wave, then, gallantly struggling, continue for a while their course up the rushing torrent, till gradually they lose way and come tumbling back, head over tail, into the pool from which half a minute before they had emerged. It is like standing by one of the jumps in an endless kind of tinny Grand National Steeple-chase; so many fish are in the air at once at any given moment that one becomes giddy with watching them. Probably a good many do in time accomplish the ascent, or perhaps get up by the salmon-ladders in mid-stream, but the great majority are swept back, over and over again. Those that make their attempt near the side, in the shallow water out of the main force of the current, are frequently taken in landing-nets (by water-bailiffs stationed there for the purpose), and
