A GREAT city was once besieged, and all its inhabitants were gathered together to consider by what means it might be protected from the enemy.

A Bricklayer earnestly recommended bricks as the best materials for successful defense.

A Carpenter with equal energy proposed timber as a preferable means of defense.

Hearing which, a Currier stood up and said, “Sirs, I differ with you wholly. There is no material for resistance equal to a covering of hides, and nothing in the present case so good as leather.”

Every man for his own trade.
