ABSTRACT
THERE are certain veins of sulphur adjacent to streams of water, which quite often catch fire, ranging widely, as flames do, to lay waste everything about them. In Iceland and Scotland, countries that are very cold, the inhabitants can view this sight and feel the continuous increase of heat. 1 In Southern Gotaland, too, in the countryside not far from the town of Vaxjo, there is a muddy lake whose fiery quality is such that, when anything that can be cooked is let down into it and drawn out with a rope, it is returned instantly, or in a short space of time, either baked or completely burnt. 2 It has been discovered also that a similar lake near Trondheim, the metropolitan city in the kingdom of Norway, possesses the same property; the chief evidence for this is that in the middle of cold seasons it never freezes, as was briefly set out above and, should it be needed, will be found mentioned below in the chapter on springs. 3 There is also the fact that in the mines beneath the northern mountains the sulphur has a warming influence, rather like the sun with its drying effect.
