substance to make Bed-matts, or Door-matts of, or to serve for Beehives,
Corn-scuttles, Chairs, or Corn-tubs, it being not unlike that kind of work, wherewith in many parts in _England_, they make such Utensils of Straw, a little wreathed, and bound together with thongs of Brambles. For in this Contexture, each little filament, fiber, or clew of the Silk-worm, seem'd about the bigness of an ordinary Straw, as appears by the little irregular pieces, ab, cd, and ef; The _Warp_, or the thread that ran crossing the Riband, appear'd like a single Rope of an Inch Diameter; but the _Woof_, or the thread that ran the length of the Riband, appear'd not half so big. Each Inch of six-peny-broad Riband appearing no less then a piece of Matting Inch and half thick, and twelve foot square, a few yards of this, would be enough to floor the long Gallery of the _Loure_ at _Paris_. But to return to our piece of Riband: It affords us a not unpleasant object, appearing like a bundle, or wreath, of very clear and transparent _Cylinders_, if the Silk be white, and curiously ting'd; if it be colour'd, each of those small horney _Cylinders_ affording in some place or other of them, as vivid a reflection, as if it had been sent from a _Cylinder_ of Glass or Horn. In-so-much, that the reflexions of Red, appear'd as if coming from so many _Granates_, or _Rubies_. The loveliness of the colours of Silks above those of hairy Stuffs, or Linnen, consisting, as I else-where intimate, chiefly in the transparency, and vivid reflections from the _Concave_, or inner surface of the _transparent Cylinder_, as are also the colours of Precious Stones; for most of the reflections from each of these _Cylinders_, come from the _Concave_ surface of the air, which is as 'twere the foil that incompasses the _Cylinder_. The colours with which each of these _Cylinders_ are ting'd, seem partly to be superficial, and sticking to the out-sides of them; and partly, to be imbib'd, or sunck into the substance of them: for Silk, seeming to be little else then a dried thread of Glew, may be suppos'd to be very easily relaxt, and softened, by being steeped in warm, nay in cold, if penetrant, juyces or liquors.
