从前，有一匹马曾经独自占有一片草场。有一天，一只雄鹿闯入了他的领地，说自己也像马一样有权利分享这里的草，不仅如此，还为自己选了一个最好的地方吃草。马一心想报复这只不请自来的鹿，便来到人那里询问是否能帮助自己惩罚鹿。人回答说：“是的，我可以尽力帮你，不过，除非你愿意让我把一根勒马的缰绳放在你嘴里，并且骑在你的背上，我才能这么做。”马同意了人的要求，于是这两个合作者很快就把鹿赶出了草场。然而，一切结束后，马才发现自己永远成了人的奴隶。

There was once a Horse who used to graze in a meadow which he had all to himself. But one day a Stag came into the meadow, and said he had as good a right to feed there as the Horse, and moreover chose all the best places for himself. The Horse, wishing to be revenged upon his unwelcome visitor, went to a man and asked if he would help him to turn out the Stag. “Yes,” said the man, “I will by all means; but I can only do so if you let me put a bridle in your mouth and mount on your back.” The Horse agreed to this, and the two together very soon turned the Stag out of the pasture: but when that was done, the Horse found to his dismay that in the man he had got a master for good.
