I still keep in mind a certain wonderful sunset which I witnessed when steamboating was new to me. 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

an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced;
the shore on our left was densely wooded, and the sombre 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 unobstructe
