The evidence is conclusive that, from the outset, industry bred heretics; agriculture, believers. Thorold Rogers has explained that the east of England, from Kent to the Wash and on to Yorkshire, was the richest part of the kingdom,[200] and Mr. Blunt, in his _Reformation of the Church of England_, has published an analysis of the martyrdoms under Mary. He has shown that out of 277 victims, 234 came from the district to the east of a line drawn from Boston to Portsmouth. West of this line Oxford had most burnings; but, by the reign of Mary, manufactures had spread so far inland that the industries of Oxfordshire were only surpassed by those of Middlesex.[201] In Wickliffe’s time Norwich stood next to London, and Norwich was infested with Lollards, many of whom were executed there. On the other hand, but two executions are recorded in the six agricultural counties north of the Humber--counties which were the poorest and the farthest removed from the lines of trade. Thus the eastern counties were the hot-bed of Puritanism. There, Kett’s rebellion broke out under Edward VI.; there, Cromwell recruited his Ironsides, and throughout this region, before the beginning of the Reformation, assaults on relics were most frequent and violent.
