A gentleman one day talking with a friend said that beasts were mere machines, and had no sort of reason to direct them; and that when they cried or made a noise, it was only one of the wheels of the clock or machine that made it.

The friend, who was of a different opinion replied, “I have now in my kitchen two dogs who take turns regularly every other morning to get into the wheel. One of them, not liking his employment, hid himself on the day that he should work, so that his companion was forced to mount the wheel in his stead, but crying and wagging his tail, he made sign for those about him to follow him. He at once led them to a garret, where he found the idle dog, drove him out and killed him at once.”
