wane

In the morning, one might say, his face was of a fine florid hue, but after twelve o'clock, meridian -- his dinner hour -- it blazed like a grate full of Christmas coals; and continued blazing -- but, as it were, with a gradual wane -- till six o'clock, PM, or thereabouts; after which, I saw no more of the proprietor of the face, ….

It was very dark, for although the sky was clear the moon was now well in the wane, and would not rise till the small hours.

The day was in its prime, the day was in its wane, and still, uneasy in mind and body, she slept on.

Sapwood, or even bark, may appear on the corners, or may have been cut off, resulting in wane, or missing timber.
