KING ANKO TO THE RESCUE The great magician Zog never slept.

He was always watchful and alert.

Some strange power warned him that his prisoners were about to escape.
Scarcely had the four left the castle by the broken window when the monster stepped from a doorway below and saw them.

Instantly he blew upon a golden whistle, and at the summons a band of wolf-fish appeared and dashed after the prisoners.

These creatures swam so swiftly that soon they were between the fugitives and the dome, and then they turned and with wicked eyes and sharp fangs began a fierce attack upon the mermaids and the earth dwellers.
Trot was a little frightened at the evil looks of the sea wolves, whose heads were enormous, and whose jaws contained rows of curved and pointed teeth.
