The deposits of the useful minerals & rocks; their origin, form, and content . on to what is the case with the lead-zinc lodes, are seldomseen in iron lodes ; when occmiing, they are either scattered throughoutthe mass or, as may often be observed, collected particularly in theneighbourhood of the walls, in which case not infrequently the lodematerial gradually merges into country. The lode width in Siegerland is remarkably great, being in many cases5-10 m. and sometimes even 20 metres. In places, as in the Petersbachmine near Eichelhardt, the St. Andreas near Bitzen, and the Neue Haardtnear Weidenau, it varies remarkably. The occurrence of irregular ore-bodies, such as the Stahlbergstockat Miisen, illustrated in Figs. 9 and 359, A, necessitates great caution whenspeculating as to the width in depth. Decrease in width may occur eitherby the approach of the walls to each other, or by the splitting of the lodeinto branches which quickly die out. Sometimes, on the other hand,the width may increase, especially where the lode makes a sharp bend, THE IRON LODESV A 797. Sforch Korrifngf. r ommei^ fisenkammer -(?T- T
