21.   The afternoon shadows were lengthening and Tabor was beginning to contemplate his long journey to a home without loved ones.

22.   The clouds of morning had blown away to the east, and soon the sun was slipping down the sky, the shadows lengthening.

23.   The sun is going down, and the shadows are lengthening.

24.   Why does time slow and twilight fall, why do shadows lengthen?
