Another trouble in Norwich, was the failure of business amongst the cloth weavers, whose trade was the chief industry of the town; the failure appears to have been, in a great measure, caused by the plague, which raged in London in 1636,[18] and put a stop for a considerable time to the weekly traffic between it and Norwich. Many of the workmen in consequence betook themselves to Holland, to obtain the means of livelihood. The same thing had happened in Bishop Corbet's time, but as in this instance it coincided with Wren's first visitation, there were not wanting those who said that his severity in enforcing conformity was the main reason of their departure. This accusation seems never to have been made at the time, but only later on, when every conceivable charge was being raked up against the Bishop. He truly says, that, often as at the council board the failure of the weaving trade and the emigration of the skilled workmen to Holland was lamented, it was never suggested that his severity was in any way the cause of it. In his defence, prepared for the House of Commons, the Bishop, besides accounting for much of the emigration by the failure of trade, consequent on the plague, reduces the number, by comparing it with the records kept at the various ports, from the alleged 3,000 to about 300, and drily says: 'The defendant humbly conceiveth that the chiefest cause of their departure was the small wages given to the workmen, whereby the workmasters grew rich, and the workmen were kept very poor.' [Sidenote: 'NO LECTURE, BUT VERY MUCH PEACE.']
