Long ago in old Atlantis, in the great City of the Golden Gate, there reigned a mighty King. One day there came to him a soldier whom he had sent out to head an expedition against a troublesome tribe on the borders of that vast empire. The soldier reported victory, and as a reward the King gave him the position of captain of the Palace guard, and placed specially in his charge the life of his own only son, the heir apparent to his throne. Not long afterwards the newly-appointed captain had an opportunity of proving his faithfulness to his trust, for when he was alone with the young Prince in the Paace gardens a band of conspirators rushed upon them and tried to assassinate his charge.
