Stephen Boileau justified the king's confidence, and maintained so strict a police that he had his own godson hanged for theft.

His administrative foresight was equal to his judicial severity.
He established registers wherein were to be inscribed the rules habitually followed in respect of the organization and work of the different corporations of artisans, the tariffs of the dues charged, in the name of the king, upon the admittance of provisions and merchandise, and the titles on which the abbots and other lords founded the privileges they enjoyed within the walls of Paris.

The corporations of artisans, represented by their sworn masters or prud'hommes, appeared one after the other before the provost to make declaration of the usages in practice amongst their communities, and to have them registered in the book prepared for that purpose.

This collection of regulations relating to the arts and trades of Paris in the thirteenth century, known under the name of _Livre des Metiers d'Etienne Boileau,_ is the earliest monument of industrial statistics drawn up by the French administration, and it was inserted, for the first time in its entirety, in 1837, amongst the _Collection des Documents relatifs d l'Histoire de France,_ published during M.Guizot's ministry of public instruction.
St.Louis would be but very incompletely understood if we considered him only in his political and kingly aspect; we must penetrate into his private life, and observe his personal intercourse with his family, his household, and his people, if we would properly understand and appreciate all the originality and moral worth of his character and his life.
Mention has already been made of his relations towards the two queens, his mother and his wife; and, difficult as they were, they were nevertheless always exemplary.

Louis was a model of conjugal fidelity, as well as of filial piety.
