"Next year the third sister went up; she was the boldest of them all...

... and so she swam up a broad river that ran into the sea. Beautiful green hills she saw, with rows of vines upon them. Palaces and mansions peeped out from among stately woods. She heard all the birds singing, and the sun shone so hot that she had to dive beneath the water to cool her burning face. In a little inlet she came upon a whole crowd of young human children; they were quite naked, and ran about and splashed in the water. She wanted to play with them, but they ran away in a fright, and then came a little black creature (it was a dog, but she had never seen a dog before) and it barked at her so dreadfully that she was terrified and took refuge in the open sea; but never could she forget the splendid woods and the green hills and the pretty children who could swim in the water, though they had no fish-tails.
