Rudyard Kipling
The Law of the Jungle (II)
When ye fight with a wolf of the pack ye must fight him alone and afar,
Lest others take part in the quarrel and the pack is diminished by war.

The lair of the wolf is his refuge, and where he has made him his home,
Not even the head wolf may enter, not even the council may come.

The lair of the wolf is his refuge, but where he has digged it too plain,
The council shall send him a message, and so he shall change it again.

If ye kill before midnight be silent and wake not the woods with your bay,
Lest ye frighten the deer from the crop and thy brothers go empty away.

Ye may kill for yourselves, and your mates, and your cubs as they need and ye can;
But kill not for pleasure of killing, and seven times never kill man.

If ye plunder his kill from a weaker, devour not all in thy pride,
Pack-right is the right of the meanest; so leave him the head and the hide.
