Up to this time all the wool grown in England had been sent to the Netherlands to be manufactured into cloth, and Philippa remembered what a source of profit and occupation it had been for her own country. She therefore set to work to establish a manufacturing colony at Norwich, and a letter was sent to John Kemp of Flanders, cloth-weaver, in which he is informed, "that if he will come to England with the servants and apprentices of his mystery, and with {221}his goods and chattels, and with any dyers who maybe willing to accompany him beyond the seas, and exercise their mysteries in the kingdom of England, they shall have letters of protection and assistance in their settlement." [[A.D. 1335.]] He came, and was the patriarch of the Norwich woollen manufactories. Philippa often visited the colony, which soon brought considerable wealth into the country, encouraging the work by her patronage, and, like a beneficent queen of the hive cherishing and protecting the working bees, she made a law that no woollen clothes should be worn except those made in England. Besides the occupation which she thus provided for hundreds of her subjects, this young queen displayed unusual foresight for a woman of her age in the tournament exhibitions she held at Norwich, by which she gave the citizens assurance of gallant protection on the part of the nobility in case of need. These festivities brought together the workers and the defenders of the nation, and Queen Philippa set them the example of mutual respect. Edward III. did not often accompany his wife on her visits to Norwich, but usually passed the time of her absence with his unhappy mother at Castle Rising.
