of digging turf, as turbare does to dig up turf. The word mor also is found in a document of the year 1246, quoted by Du Cange; who however has not introduced it into his dictionary586. It seems to be the same as mariscus and marescus. Brito, who lived about 1223, describing the productions of Flanders, says, “Arida gleba foco siccis incisa marescis587.” That the last of these words signifies a turf-bog is proved by a passage of Lambert, who lived at Ardres about the year 1200: “Quendam similiter mariscum, ut aiunt, proprium perfodi fecit, et in turbas dissecari.”

      In Sweden turf was first made known at a very modern period by some navigators in the district of Halland; and in the time of Charles XI. much trouble was taken to introduce it as fuel. In 1672 the town of Laholm obtained an exemption from duty for the turf dug up in the lands belonging to it.

      [In 1842 a patent was taken out by Mr. Williams for compressing peat into a dense mass, resembling coals. It is said to be superior to coal in its properties of producing heat by combustion, forming an excellent charcoal or coke. It is asserted that this charcoal is much more combustible than that of wood, and very useful in the manufacture of fire-works. The process is as follows:—Immediately after being dug it is triturated under revolving edge-wheels faced with iron plates perforated all over the surface, and is forced by the pressure through these apertures, till it becomes a kind of pap, which is freed from the greater part of its moisture by a hydraulic press. It is then dried, and converted into coke in the same manner as pit-coal. The factitious coal of Mr. Williams is made by incorporating pitch or rosin, melted in a caldron with as much peat-charcoal ground to powder as will form a tough doughy mass, which is then moulded into bricks.]

      FOOTNOTES

      In Kronijck der Kronijcken, door S. de Vries, printed at Amsterdam in 1688, the following passage occurs, vol. v. p. 553:—“About this time (1221) the digging of turf was first practised, which in some measure made amends for the damage occasioned by the sea-water, and by which several acquired great riches.”

      Some Dutch writers make turf-digging to be of much higher antiquity, and in support of this opinion quote an old chronicle in rhyme, in which mention is made of a donation by Gerolf count of Friesland; but I am not acquainted with the antiquity of that chronicle, and of the letter of donation there is only a Flemish translation. See Berkhey, Nat. Hist. v. Hol. vol. ii. p. 552.
