Now it came to pass that the Town Watch having had certain complaints made to them that persons had been bitten in the Vita Publica by rats, doubted of their duty to destroy these ferocious creatures; and they held investigation, summoning the persons bitten and inquiring of them how it was that in so dark a street they could tell that the animals which had bitten them were indeed rats. Howbeit for some time no one could be found who could say more than what he had been told, and since this was not evidence, the Town Watch had good hopes that they would not after all be forced to undertake this tedious enterprise. But presently there came before them one who said that he had himself seen the rat which had bitten him, by the light of an old man's lanthorn. When the Town Watch heard this they were vexed, for they knew that if this were true they would now be forced to prosecute the arduous undertaking, and they said: "Bring in this old man!" Cethru was brought before them trembling. "What is this we hear, old man, about your lanthorn and the rat? And in the first place, what were you doing in the Vita Publica at that time of night?" Cethru answered: "I were just passin' with my lanthorn!" "Tell us--did you see the rat?" Cethru shook his head: "My lanthorn seed the rat, maybe!" he muttered. "Old owl!" said the Captain of the Watch: "Be careful what you say! If you saw the rat, why did you then not aid this unhappy citizen who was bitten by it--first, to avoid that rodent, and subsequently to slay it, thereby relieving the public of a pestilential danger?" Cethru looked at him, and for some seconds did not reply; then he said slowly: "I were just passin' with my lanthorn." "That you have already told us," said the Captain of the Watch; "it is no answer." Cethru's leathern cheeks became wine-coloured, so desirous was he to speak, and so unable. And the Watch sneered and laughed, saying: "This is a fine witness." But of a sudden Cethru spoke: "What would I be duin'--killin' rats; tidden my business to kill rats." The Captain of the Watch caressed his beard, and looking at the old man with contempt, said: "It seems to me, brothers, that this is an idle old vagabond, who does no good to any one. We should be well advised, I think, to prosecute him for vagrancy. But that is not at this moment the matter in hand. Owing to the accident--scarcely fortunate--of this old man's passing with his lanthorn, it would certainly appear that citizens have been bitten by rodents. It is then, I fear, our duty to institute proceedings against those poisonous and violent animals." And amidst the sighing of the Watch, it was so resolved. Cethru was glad to shuffle away, unnoticed, from the Court, and sitting down under a camel-date tree outside the City Wall, he thus reflected: "They were rough with me! I done nothin', so far's I can see!"
