Ingall says the vein-filling minerals consist of quartz, barite, calcite and fluorite.In these occur various metallic minerals, viz.: blende, galena, pyrites of variousspecies and occasionally some sulphurets of copper, whilst the silver occurs as argentiteand in the native state, the former being the more common. At places the veins carrya dark green, probably chloritic, material, which on some surfaces has a bright waxy * Geology of Canada, 1863, pages 506 and 703. t Report on Klines and Mining on Lake Superior, by E.

1913 Lake Superior Silver Deposits 109 lustre, whilst occasionally a soft, greasy, talcose material, probably saponite, accom-panies the ore, notably at the Beaver mine, and to a lesser extent at one or two otherplaces. Carbon in various forms has also been found here and there, whilst in someof the vugs in the veins which have been found near the surface, stiff clay and ochreousmaterial have sometimes been obtained along with nuggets of argentite, the former,however, having evidently been washed in from the surface and thus imbedded thesilver minerals already existing in the vugs. The same writer further states: These, then, are the mineral constituents ofthese veins, but the Silver Islet vein forms somewhat of an exception in that it carried,besides these, various arsenical and antimonial ores of silver with compounds of nickeland cobalt and other metallic minerals which have so far not been found in the restof the veins (?). Other salient features were the pink and cream-colored do
