It draws me on to the deep green pool inclosed about by rocks--a pool to stand near and think into. The purple rock, dotted with black moss; the white rock; the thin scarlet line; the green water; the overhanging tree; the verdant moss upon the bank; the lady fern--are there still. But I see also now a little pink somewhere in the water, much brown too, and shades I know no name for. The water is not green, but holds in solution three separate sets of colours. The confervae on the stones, the growths beneath at the bottom waving a little as the water swirls like minute seaweeds--these are brown and green and somewhat reddish too. Under water the red rock is toned and paler, but has deep black cavities. Next, the surface, continually changing as it rotates, throws back a different light, and thirdly, the oaks' yellow-green high up, the pale ash, the tender ferns drooping over low down confer their tints on the stream. So from the floor of the pool, from the surface, and from the adjacent bank, three sets of colours mingle. Washed together by the slow swirl, they produce a shade--the brown of the Barle--lost in darkness where the bank overhangs. Following the current downwards at last the river for awhile flows in quietness, broad and smooth. A trout leaps for a fly with his tail curved in the air, full a foot out of water. Trout watch behind sunken stones, and shoot to and fro as insects droop in their flight and appear about to fall. So clear is the water and so brightly illuminated that the fish are not easily seen--for vision depends on contrast--but in a minute I find a way to discover them by their shadows. The black shadow of a trout is distinct upon the bottom of the river, and guides the eye to the spot; then looking higher in the transparent water there is the fish. It was curious to see these black shadows darting to and fro as if themselves animated and without bodies, for if the trout darted before being observed the light concealed him in motion. Some of the trout came up from under Torre-steps, a singular structure which here connects the shores of the stream. Every one has seen a row of stepping-stones across a shallow brook; now pile other stones on each of these, forming buttresses, and lay flat stones like unhewn planks from buttress to buttress, and you have the plan of this primitive bridge. It has a megalithic appearance, as if associated with the age of rude stone monuments. They say its origin is doubtful; there can be no doubt of the loveliness of the spot. The Barle comes with his natural rush and fierceness under the unhewn stone planking, then deepens, and there overhanging a black pool--for the shadow was so deep as to be black--grew a large bunch of marsh-marigolds in fullest flower, the broad golden cups almost resting on the black water. The bridge is not intended for wheels, and though it is as firm as the rock, foot passengers have to look at
