Cobwebs from an Empty Skull

A wild horse meeting a domestic one, taunted him with his condition of servitude.  The tamed animal claimed that he was as free as the wind.

“If that is so,” said the other, “pray tell me the office of that bit in your mouth.”

“That,” was the answer, “is iron, one of the best tonics in the materia medica.”

“But what,” said the other, “is the meaning of the rein attached to it?”

“Keeps it from falling out of my mouth when I am too indolent to hold it,” was the reply.

“How about the saddle?”

“Fool!” was the angry retort; “its purpose is to spare me fatigue:  when I am tired, I get on and ride.”
