A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.
