Their way of making pitch (says he) is thus: They take sapines, that is, that part of the fir, so far as it hath no knots; and shaving away the extream parts, leave only that which is nearest to the middle, and the pith: That which remains, they call _dadi_ (from the old Greek word Δᾶδες, whence the Latin, _taeda_): These they split into small pieces, and laying them on a furnace, put fire to the upper part, till they are all burnt, the liquor in the mean time running from the wood, and let out from the bottom of the furnace, into a hole made in the ground, where it continues like oyl: Then they put fire to’t, and stir it about till it thicken, and has a consistence: After this, putting out the fire, they cast chalk upon it, and draw it out with a vessel, and lay it in little places cut out of the ground, where it receives both its form, and a firmer body for easie transportation: Thus far the archbishop; but it is not so instructive and methodical as what we have describ’d above.

Other processes for the extracting of these substances, may be seen in Mr. Ray’s _Hist. Plant._, already mentioned, lib. xxix. cap. 1. And as to pitch and tar, how they make it near Marselles, in France, from the pines growing about that city, see _Philos. Trans._ n. 213. p. 291. _an._ 1696, very well worthy the transcribing, if what is mentioned in this chapter were at all defective.
