One child is Fox. He has a knotted handkerchief, and a home to which he may go whenever he is tired, but while out of home he must always hop on one leg. The other children are geese, and have no home. When the Fox is coming out he says,—

The Fox gives warning

It's a cold frosty morning.

After he has said these words he is at liberty to hop out, and use his knotted handkerchief. Whoever he can touch is Fox instead, but the geese run on two legs, and if the Fox puts his other leg down, he is hunted back to his home.
