The officer leaned back against the soft cushion of the carriage, roaring with laughter. "They fly then, I presume," he jeered. "By Hercules, you must tell this all over again to Septimus Favonius. I promise you that he will love you." They were passing along a broad avenue bordered by old trees. There was no pavement and the surface of the street was deep with dust. The houses were built quite up to the street line and where there was space between adjacent houses a high wall closed the aperture, so that each side of the street presented a solid front of masonry broken by arched gateways, heavy doors, and small unglazed windows, heavily barred. "These are residences?" asked von Harben, indicating the buildings they were passing. "Yes," said Mallius. "From the massive doors and heavily barred windows I should judge that your city is overrun with criminals," commented von Harben. Mallius shook his head. "On the contrary," he said, "we have few criminals in Castrum Mare. The defenses that you see are against the possible uprising of slaves or invasions by barbarians. Upon several occasions during the life of the city such things have occurred, and so we build to safeguard against disaster in the event that there should be a recurrence of them, but, even so, doors are seldom locked, even at night, for there are no thieves to break in, no criminals to menace the lives of our people. If a man has done wrong to a fellow man he may have reason to expect the dagger of the assassin, but if his conscience be clear he may live without fear of attack." "I cannot conceive of a city without criminals," said von Harben. "How do you account for it?" "That is simple," replied Mallius. "When Honus Hasta revolted and founded the city of Castrum Mare in the 953rd year of Rome, Castra Sanguinarius was overrun with criminals, so that no man dared go abroad at night without an armed body-guard, nor was anyone safe within his own home, and Honus Hasta, who became the first Emperor of the East, swore that there should be no criminals in Castrum Mare and he made laws so drastic that no thief or murderer lived to propagate his kind. Indeed, the laws of Honus Hasta destroyed not only the criminal, but all the members of his family, so that there was none to transmit to posterity the criminal inclinations of a depraved sire. "There are many who thought Honus Hasta a cruel tyrant, but time has shown the wisdom of many of his acts and certainly our freedom from criminals may only be ascribed to the fact that the laws of Honus Hasta prevented the breeding of criminals. So seldom now does an individual arise who steals or wantonly murders that it is an event of as great moment as any that can occur, and the entire city takes a holiday to see the culprit and his family destroyed."
