Ore from Old Cut N. of Gatesburg 57.52 



All these ores were examined for Sulphur and Sulphuric acid, but not 

 a single one gave a decided reaction for either. They were also examined 

 for Titanium, Chromium, Vanadium, and other metals, but with negative 

 results. 



Their only constituent, which has an injurious effect upon the quality 

 of the iron, produced from the same, is phosphoric acid ; most of them, 

 however, contain it in too small a quantity to be of much harm. Oaly 

 two of the samples contain it in a larger proportion. 



For better comparison, I will arrange the amounts of Phosphorus 

 which would be contained in 100 parts of iron, provided no loss of either 

 would be sustained : 



Fibrous ore of Bull Bank 0.06 Phosphorus.
