Note 5 — BOOK IV.

Quadratum. Glossary, vierung. The vierung in old Saxon title meant a definite zone on either side of the vein, 31/2 lachter (lachter = 5 ft. 7.5 inches) into the hangingwall and the same into the footwall, the length of one vierung being 7 lachter along the strike. It [Pg 81]must be borne in mind that the form of rights here referred to entitled the miner to follow his vein, carrying the side line with him in depth the same distance from the vein, in much the same way as with the Apex Law of the United States. From this definition as given in the Bergwerk Lexicon, p. 585, it would appear that the vein itself was not included in the measurements, but that they started from the walls.
