This text is justified, meaning that spaces are stretched so that the text
forms a "block" with flush edges at both sides.
First line indents and hyphenation play nicely with justified text.

In olden times when wishing still helped one, there lived a king whose
daughters were all beautiful; and the youngest was so beautiful that the sun
itself, which has seen so much, was astonished whenever it shone in her face.
Close by the king’s castle lay a great dark forest, and under an old lime-tree
in the forest was a well, and when the day was very warm, the king’s child
went out into the forest and sat down by the side of the cool fountain; and
when she was bored she took a golden ball, and threw it up on high and caught
it; and this ball was her favorite plaything.
