Industry 

A virtue inculcated amongst Masons, because by it that are enabled not only to support themselves and families, but to contribute to the relief of worthy distressed Brethren.  "All Masons," says the Charges of 1722, 'shall work honestly on working days that they may live creditably on holy days."  The Masonic symbol of industry is the Beehive, which is used in the third degree.
