It was their first summer in boots, and they hated them, so they took them off, and slung them round their necks, and paddled joyfully over the dripping turf where the shadows lay the wrong way, like evening in the East. The sun was well up and warm, but by the brook the last of the night mist still fumed off the water.
This is an extract from "Rewards and Fairies" by Rudyard Kipling.
I can not understand the meaning of:
"the dripping turf where the shadows lay the wrong way, like evening in the East."
What does "the shadows lay the wrong way" mean?
