The assertion of Winsem and others, that the practice of digging turf first became common after the year 1215, is undoubtedly founded on information obtained from Sibrand Leo’s Vitæ Abbatum Horti Divæ Virginis seu Mariengard[588]; but this writer died in 1588, and can by no means be adduced as an evidence: he even says himself that turf-digging in 1212 was a new occupation.
The conjecture that the Netherlanders, who in the twelfth century established themselves as colonists in some districts of Germany, and particularly Lower Saxony, first made known there the preparation and use of this kind of fuel is improbable, or at any rate not proved[589]. It is improbable, because the Chauci, the oldest inhabitants of that country, burnt turf before that period.
It is related by the Icelanders that Einar, Count or Earl of Orkney or of the Orkney islands, discovered turf there, and on that account was named Torffeinar. He was the son of Raugnwauld, or Rognwald, earl of Mören, Sued and Nordmör in Norway, in the time of the celebrated Norwegian King Harold, commonly called Haarfager or Pulcricomus, on account of his beautiful hair[590]. He must have lived therefore in the middle of the ninth century; but on so trifling a subject I shall enter no further into the labyrinth of the Icelandic Saga.
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 later times turf began to be burned to charcoal, sometimes in kilns, and sometimes in furnaces built for that purpose, by which this advantage is obtained, that it kindles sooner, burns with less air, and forms a more moderate and uniform fire without much smoke. This method of reducing turf to charcoal, which is still practised in some parts of Bohemia, Silesia, and Upper Saxony, was, it appears, proposed about the year 1669, by the well-known John Joachim Becher, who recommended at that time a method of depriving coals of their sulphur by burning them, and the use of naphtha or rock-oil procured from them by that process[591]. The burning of turf to coal seems to have been first made known in Germany by Hans Charles von Carlowitz, chamber-counsellor, and principal surveyor of the mines of the electorate of Saxony[592]. To save wood and promote the benefit of the mines he sought for turf; and having discovered it, he then endeavoured to find out some method of rendering it fit to be employed in the melting-houses, and this was the reducing to coal, which, as he himself says[593], he first attempted in kilns at Scheibenberg, in the year 1708. At the Brocken the first experiments were made in 1744, with turf which had been dug up several years. This was announced by F. C. Brückman in 1745[594], as a new invention; but an anonymous writer stated[595] soon after, that this charring had been long used in the district of Hadeln, and that the smiths there employed no other kind of coals for their work.
[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
[573] In Siberia, a village which stood on a turf-moor was, on account of its marshy situation, removed to another place; and that the remains might be more easily destroyed, they were set on fire. The flames having communicated to the soil, which was inflammable, occasioned great devastation; and when Gmelin was there, it had been continually burning for half a year. See Gmelin’s Reisen durch Russland, vol. i. p. 22.
[574] The rustics, in despair, when they found the fire was unquenchable either by rain or by the river-water which they poured over it, threw in heaps of stones, beat down the flames issuing from the interstices with clubs, and as the fire became subdued flung on their clothes, which being made of skins and wetted, eventually extinguished the conflagration. See Tacitus, An. xiii. 57.
