The Cock and the Jewel_英语寓言故事

a cock, scratching for food for himself and his hens, found a
precious stone and exclaimed:
"if your owner had found thee, and
not i, he would have taken thee up, and have set thee in thy
first estate; but i have found thee for no purpose.
i would
rather have one barleycorn than all the jewels in the world."
