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?"
