A PIGEON, oppressed by excessive thirst, saw a goblet1 of water

　　painted on a signboard. Not supposing it to be only a picture,

　　she flew towards it with a loud whir and unwittingly dashed

　　against the signboard, jarring herself terribly. Having broken

　　her wings by the blow, she fell to the ground, and was caught by

　　one of the bystanders.

　　Zeal2 should not outrun discretion3.
