Although the South or Messaba range is generally considered as pro-ducing titaniferous ores, Mr. C. S. Robinson reports that out of 15samples, some of which are known and the rest reported to have comefrom this range, 9 were without titanic acid, and 6 carried it in amountsfrom a trace to about 12 per cent. Of these 6 samples, 3 were reportedfrom the same property, whereas, with the possible exception of 2 fromthe same land, the 9 samples were taken from different locations.
