In the sixteenth century flax was apparently grown upon most farms, the statutes 34 Hen. VIII, c. 4, and 5 Eliz., c. 5, obliging every person occupying 60 acres of tillage to have a quarter of an acre in flax or hemp, and Moryson says the husbandmen wore garments of coarse cloth made at home, so did their wives, and 'in generall' their linen was coarse and made at home.[240] 'Good flax and good hemp to have of her own In Maie a good housewife will see it be sowne', sings Tusser. The statute of Henry VIII enjoined the sowing of flax and hemp because of the great increase of idle people in the realm, to which the numerous imports, especially linen cloth, contributed. Saffron also was much grown, that at Saffron Walden in Essex was said to be the best in the world, the profit from it being reckoned at L13 an acre. Its virtues were innumerable, if we may believe the contemporary writers; it flavoured dishes, helped digestion, was good for short wind, killed moths, helped deafness, dissolved gravel, and, lastly, 'drunk in wine doth haste on drunkenesse.' The most important novelty of this century was the potato, which the colonists, sent out in 1586 by Sir Walter Raleigh, brought from Virginia to Ireland, though it had been introduced into Europe by the Spaniards before this. According to Gerard, the old English botanist, it was, on its first introduction from America, only cultivated in the gardens of the nobility and gentry as a curious exotic; and in 1606 it occurs among the vegetables considered necessary for a nobleman's household.[241] It is curious to find Gerard comparing it to what he calls the 'common potato', in reality the sweet potato brought to England by Drake and Hawkins earlier in the century. In James I's reign the root was considered a great delicacy, and was sold to the queen's household at 2s. a lb., an enormous price. Like most agricultural novelties it spread very slowly, but about the middle of the seventeenth century began to be planted out in the fields in small patches in Lancashire, whence it spread all over the kingdom and to France.[242] At this date it was looked upon as a very second-rate article of food, if we may judge by the _Spectator_ (No. 232), which alludes to it as the diet of beggars. About 1690, Houghton says, 'now they begin to spread all the kingdom over,' and recommends them boiled or roasted and eaten with butter and sugar.[243] Eden notes its increasing popularity during the eighteenth century, and by his time (the end of that century) in many parts it was the staple article of food for the poor; in Somerset the children mainly subsisted on it, and in Devon it was made into bread. Its cultivation on a large scale in the field did not, however, spread all over England till the Napoleonic war, and the ignorance and prejudice against it lasted for long; even Cobbett called it 'the lazy root,' and whole potatoes were used for seed regardless of the number of eyes.
