"I suppose there's nothing else to be done," sighed Sidigunda, and throwing the scarf over her head, she poured a few drops from the bottle upon her shoe.

"Turn into a fish and carry me down to the Sea-city!" she said.

In a moment she felt herself sinking through the clear water, deeper and deeper, with a delicious drowsy feeling that almost soothed her to sleep. She knew she was not asleep though, for she could see the misty forms of sea creatures, darting about in the dim shadows, and great waving sea-weeds—crimson, yellow, and brown—floating up from the rippled sand beneath.

And now the shoe swum straight on, darting through the water like an eel; until a large town came in sight, with high walls and Palaces, and shining domes covered with mother-o'-pearl.

They stopped at a great gate, before which a fish dressed as a sentry was standing.

As soon as he saw the little Princess, he drew his sword, and came gliding towards her.

"Your name and business!" he enquired, in a high thin voice.

"I am Princess Sidigunda, seeking my golden shoe, and I bring this from the Sea-Troll," said the Princess courageously. "Will you tell me where I am to find the Trolls of the Palace?"

The fish handed the shell back sulkily, and pointed up the street.

"Go straight through till you come to the marble building with the pearls over the door," he said; and gave the Princess a poke with the handle of his sword, that pushed her through the gate, almost before she had time to draw on her golden shoe again.
