Slowly, wearily, the yellow sun went down the sky. From the east the night came on, as dark and as deep as the night that has no ending. The last rays of the sun washed down over the planet, over the low rounded hills and the trees that grew on them, through the shallow valleys where the grass grew rank and luxurious. The last songs of the birds came undisturbed through the dusk. A deer snorted. From somewhere came the bark of another animal, a bark that ended in a howl, long-drawn and mournful.
