place by mechanical disruption, by land-slips, or even also 

 by desiccation. 



694. The veins are not prolonged into the kind of 

 rock that underlies them, as e. g. gneiss veins into 

 granite, and so on ; they have hence originated from 

 above. 



695. They are open and wider above and strike out 

 below; they have not therefore originated by a force 

 acting from beneath. 



696. In the schistose rock they form generally trans- 

 verse fissures. 



697. There was a time in which the veins stood empty, 

 as well as a time in Avhich the primary valleys w^ere empty, 

 namely unreplenished with gneiss, mica- schist, and such 

 like minerals. 



b. PRODUCTION OF ORE. 



698. Geogeny takes two directions ; the one passes 

 upon the periphery into the splitting action of light, the 

 other into the abyss, where darkness reigns. 



699. The valleys were the condition that conduced 

 to the differentialization of the earths, because in them 

 light had power to produce the highest polarity. By the 

 valleys the Earthy has been separated into its principles ; 

 silex has separated into clay and talc, to which finally 

 carbonate calcareous earths and salts succeeded. 



700. The Earthy cannot subsist in its identity in the 

 broad valleys ; the earth cannot be represented as the 

 pure symbol of gravity. All bodies that have originated 

 upon the surface of the planet are oxydes or salts. 



701. If the earth- difference be generated in the illu- 

 mined valleys, so must the earth-identity be produced in 

 the dark valleys ; for it is the absence of light alone that 

 allows the purely Basic to subsist. This earth generated 

 out of gravity is the ore. 



702. The ore is a child and a treasure of darkness ; 

 where light is, it must vanish ; it cannot endure its gaze. 

 Metal when exposed to day is given up to annihilation, 

 to oxydation.
