A supposititious code of severe laws for the regulation of religious and personal conduct in the colonies of Connecticut and New Haven; hence any rigid Sunday laws or religious regulations. The assertion by some writers of the existence of the blue laws has no other basis than the adoption, by the first authorities of the New Haven colony,' of the Scriptures as their code of law and government, and their strict application of Mosaic principles.
