A common Peasant casts forth (or sows) his Seed in a Field well dunged and prepared, this Seed after putrefaction, sprouts forth of the Earth by the operation and furtherance of the Elements, and sets before our Eyes the Matter of Flax together with its Seed which it brings with it augmented; this Flax is pluck'd up, and separated from its Seed; but this Flax cannot be used and prepared for any work profitably, except it be first putrefied and rotted in water, whereby the Body is opened, and gains an ingress of its doing good; after this putrefaction and opening, it is again dried in the Air and Sun, and by this coagulation it is again brought into a Formal Being, that it may do future service. This prepared Flax is afterwards buck'd, beaten, broken, peel'd, and last of all dress'd, that the pure may be separated from the impure, the clean from the filth, and the fine from the course; which otherwise could not be done at all, or brought to pass without the preceding preparation; this done, they spin Yarn of it, which they boil in water over the Fire, or else with Ashes set in a warm place, whereby it is purified afresh, whereby the filth and superfluities are fully separated from it, and after a due washing the Yarn is dried again, delivered to the Workmen, and Cloth weaved of it; this Cloth is purified or whitened by a frequent casting of water upon it, cut in pieces by Taylors, and other people, so converted to future services in houshold affairs, and when this Linnen is quite worn out, and torn, the old Rags are gathered together, and sent to the Paper-Mills, whereof they make Paper, which is put unto divers uses. If you lay Paper upon a Metal or Glass, kindle and burn it, the vegetable _Mercury_ comes forth and flies away into the Air, the Salt remaines in the ashes and the combustible _Sulphur_ which is not so quickly consumed in the burning, dissolves to an Oil, which is a good Medicine for dim and defective Eyes. This Oil hath in it a great fatness, which is the Matter of the Paper, contained originally in the Seed of the Flax; so that the last Matter of the Flax which is Paper, must again be dissolved into the first Matter, which is the fat Sulphurous Oyliness of the Flax-seed, together with the separation of its _Mercury_ and _Salt_, that so the first may be made of the last, and the ground-work revealed, so the Virtues and Operations known by the first. And though this Discourse be gross and not subtil, yet you may learn thereby to know what is subtile and secret; for that which is subtile must be infused into the ignorant by course Examples, that thereby they may be taught to reject the gross, and to embrace that which is subtile.
