…There came a time of famine in Ireland, and there was not food enough to go around, as has often happened there from the earliest days until even now. Comgall and his household at Bangor were very hungry. But what made it hardest to bear was that they knew where there was plenty of food close by, if only they could get it. For Croadh was a great Prince who lived in the neighborhood, and Croadh had barns and storehouses full of grain which could be made into bread. But he was a selfish, stingy man and would not give away or even sell his stores, for he would rather see the people starve. Now Croadh had a wicked old mother living in his palace, who was even more cruel than himself. Her name was Luch, and Luch means in Irish ” the Mouse.” And it was her name which put an idea into Comgall’s head.

After sending all sorts of messengers to beg Croadh to give them some of his grain ; after trying all sorts of ways to make him sell it, Comgall went himself to the Prince’s palace to see what he could do. He carried with him a beautiful silver goblet which had been given him by some one as a present, and it was worth many bushels of grain.

Comgall strode into the Prince’s hall and stood before Croadh holding out the goblet in his hand. And he said, “Here, O Prince, is a valuable thing. We are starving in the monastery, and silver we cannot eat. Give me and my monks some of your golden grain and I will exchange for it the silver cup. Be merciful, Croadh, and hear me.” But the Chief only laughed and said mockingly, ” Not so. You keep your silver goblet and I will keep my golden grain. Your beggarly pupils shall not eat of my stores. I want all, every grain, for my old Mouse.” And by that word he meant his mother, the black-eyed, wrinkled, gray old Luch, whose name meant “the Mouse.” For she was the most miserly, wicked, old woman in the world, and she had made him promise not to give up any of the grain. Then Comgall was angry, because he saw that the Prince meant to see the people starve.

 “Very well,” he said, fixing his eyes sternly upon Croadh, “as you have said, so shall it be. The mouse shall have your grain.” And drawing his robe about him he strode home with the useless silver goblet.

As I have said, the mice were Comgall’s friends. He had only to call them and explain what the hard-hearted Prince had done; he had only to tell the mice what he wished them to do, and the matter was settled. The word spread through the kingdom of the mice, carried by the quickest messenger with the shortest tail. All the mice became enemies of Croadh. And there were many mice in Bangor in those days.

That very night when every one was asleep, out of every hole and corner came peeping little pointed noses and quivering whiskers. And a great procession of long-tailed tiny things formed into line and crept along, and along, up the hill, and up the walls, and into the barns of Croadh. A legion of mice, thousands upon thousands of them in a gray-uniformed army, pounced upon the Prince’s precious grain and ate up every kernel.

So the next morning when Croadh went to his barns he found them empty. There was not so much as a single yellow dot of grain left anywhere. But out of every crack and crevice peeped a pair of twinkling black eyes which watched him saucily. Then Croadh began to bellow and roar with anger, and the wicked old woman Luch, his mother, came hobbling in to see what was the matter. But when the mice saw her they gave a chorus of fierce squeaks as if crying ” Mouse! Mouse! Mouse! ” Then Croadh remembered what Comgall had said, that the mouse should have his grain after all. And he guessed what the Saint had meant, and knew that Comgall had taken this way to punish a selfish and cruel man.
