[vol. VI. 
frequently accompanies other arenaceous materials in the beds of watercourses, n some cases 
probably in sufficient abundance to repay collection by the native iron-smelters. The differ¬ 
ence in specific gravity causes a natural separation of the ferruginous and silicious grains, 
so that the former could be collected with only a moderate percentage of foreign matter, 
which could he almost wholly eliminated by washing. As far as I am aware however, no 
attempt is made to utilize this rich detrital ore, while a few miles to the north, the vastly 
inferior ferruginous beds of the Barakar sandstones are laid under contribution.
