7. Now the certain Means and Way not onely to prevent the Generation of this Vermin, but also to preserve Health and Strength, are Straw, or rather Chaff-Beds, with Ticks of Canvas, and Quilts made of Wooll or Flocks to lay on them; which certainly is the most easie and pleasant Lodging that can be invented: and a little Custom will make it appear friendly to Nature, and in every respect far beyond the softest Feather-beds, on which, when a Man lies down, he sinks into them, as into an Hole, with Banks rising on each side of him; especially if two lie together, when first they go to Bed they lie close, and after a little time, when they begin to be hot or sweat, they are generally willing to lie a little further off, that they may cool themselves, but cannot do it without great difficulty and trouble, by reason of the softness of the Bed, and those Banks that rise on each side. Besides, such soft Feather-Beds do over-heat the Reins and Back, making all the Parts tender, and causing Sweatings and many other Inconveniencies to attend the Body. Feather-beds also are nothing so easie as Quilts, after a little time being accustomed to them; they are also extream fulsom, and by their Heat they do powerfully dry up the Radical Moisture, causing a general Faintness to attend the whole Body. But, on the contrary, hard, even Beds, that lie smooth, are not only easie through custom, as is mentioned before; but a Man may turn freely, both sleeping and waking: They harden and strengthen the whole Body, especially the Back and Reins, make the Nerves and Sinews strong, preventing the immoderate Evacuations by Sweating, and keeping the Body in a temperate Heat. Besides, such Beds may be often changed, with but little Trouble, and less Cost; they send forth no stinking Fumes or Steams, as Feather-beds do; but are sweet and clean. Certainly nothing is more healthy, next to Temperance in Meat and Drink, than clean hard Beds.
