and violet. During the prevalence of the scarlet and orange hues, the moon, then young, shining at the edge of the sunset, appeared faintly green; and people remarked how curious a green moon looked on a blue sky, for it was just where the sunset vapour melted into the upper sky. At the same moment the gas-lamps burned green—rows and rows of pale green lights.

Another time the reflection of the sun's rays takes the form of a gigantic and
