to the east. In the hills somewhere southwest of this angle of the 

 highway another occurrence has been reported. 



Commercial value of the above titaniferous ores. So mucli 

 interest has been felt in the exposures of these ores that a few re- 

 marks should be made upon their commercial values. Enough 

 analyses are now in hand to illustrate in a satisfactory manner what 

 may be expected. The percentages in iron, titanic oxid, phosphorus 

 and sulfur may be first summarized, with the name of the sampler.

It is at once apparent that all these ores are extremely low grade, 

 the richest being 44.19 and only two others reaching 40. . Since 

 under present conditions and those which are likely to continue for 

 many years, no magnetite under 50 per cent in iron is of importance 

 as a source of lump ore, unless it should have exceptional purity 

 in phosphorus and sulfur, be lacking in titanium, and be in addition 

 located near a furnace, there is little encouragement to look with 

 favor upon bodies of this type. 



The percentages in phosphorus and sulfur are also important 

 features. In sulfur the ores are obviously low. In phosphorus they 

 are variable. In instances such as Split Rock, and Tunnel moun- 

 tain, they are very low ; in others tliey are quite high as at Lincoln 

 pond. There is a somewhat widely prevalent impression that the 

 titaniferous ores always run low in phosphorus and sulfur but this 

 is clearly unjustified. As with other ores each case must be 

 sampled by itself. 



The presence of vanadium in these ores is a matter of much 

 scientific interest and since the element has come into such ex- 

 tended use for high grade steels some have looked to the titanif- 

 erous ores as possible sources. If we summarize the results given 

 above, we obtain :
