The effect of the mortality upon trade and industry was, momentarily, to paralyse them. Of the great wool-trade, Rogers, the historian of English prices, says: “Nothing, I think, in the whole history of these prices is more significant of the terror and prostration induced by the plague than the sudden fall in the price of wool at this time. It is a long time before a recovery takes place[367].” But from 1364 to 1380, the price of wool was uniformly above the average; and, if there be any accuracy in Avesbury’s figures already given for the years following 1355, the export of bales of wool to the Continent (100,000 sacks in a year, he says, each sack being a bale of the present colonial size, or weighing about three hundredweights) meant a very considerable amount of labour, tonnage and exchange. Among other articles of export, we hear specially of iron, in a petition to Parliament of 28 Ed. III. (1354); the price of iron had risen to four times what it was before the plague, and it was desired to stop the export of it and to fix the price[368]. The effect of the mortality upon the industries of the country was shown most in Norwich. That city was the centre of the Flemish cloth-weaving, which had been flourishing in Norfolk for some twenty years, under the direct encouragement of Edward III., and of a protective statute against foreign-made cloth. Before the pestilence, Norwich was the second city in the kingdom. In the king’s warrant for men-at-arms, which was indeed issued in 1350, but may be taken as drawn up on the old lines and irrespective of the pestilence, the quota of Norwich is rated at 60, London’s being 100, Bristol’s and Lynn’s 20 each, that of Coventry, Gloucester, Hereford, Shrewsbury, Winchester, Sarum, Oxford, Canterbury and Bury St Edmund’s 10 each, and of other towns from 8 to 1 each, York not being mentioned. But in the Subsidy Roll of 1377, which shows how many persons, above the age of fourteen, paid the poll-tax of a groat in each county and in each principal town, Norwich comes sixth in the list instead of second, being far surpassed in numbers by York and Bristol, and surpassed considerably by Coventry and Plymouth. So far from being in a proportion to London of 60 to 100, it is now in a proportion of 3952 to 23,314, its whole population, as estimated, being 7410 against 44,770 in the capital which at one time it bade fair to rival. It had lost heavily in the Black Death, and so had the populous district around it, where the Flemish industries and trade were planted in numerous villages. By 1368, ten of the sixty very small parishes of Norwich had disappeared, and fourteen more disappeared by degrees, the ruins of twenty of them being still visible[369].
