STRENGTH OF POUNDS PER SQUARE INCH. 



Iron from Salisbury, Conn., by niean"of 40 trials, 58.009 



" Sweden, 4 trials, ' 58.184 



" Centre county. Pa., 1 5 trials, 58.400 



" Lancaster " " 2 " 58.661 



" Mclntyre, Essex county, N. J., 4 trials, 58.912 



England Cable Bolt, E. V., 5 trials, 59.105 



Russia, 5 trials, 76.069 



Carp River, Lake Superior, 89.582 



By the above data it will be seen that the Lake Superior Iron sus- 

 tained a pressure of 13.513 pounds more to the square inch than Rus- 

 sia Iron, which was found to sustain 16.694 more per square inch than 

 English cable bolt, which is known to be the strongest iron England 

 iT^kes ; thereby showing the Lake Superior Iron to be about 54 per cent 

 stronger than the best English cable bolt. 



This Iron has been so thoroughly proven in New York, Boston, Pitts- 

 burg, Cincinnati, and at the United States Navy Yards within the past 

 five years, by manufacturing it into car axles, boiler plate, steam en- 

 gines, wire, tacks, nails, (the cut nail being found to clinch as well as the 

 ordinary wrought nails,) and the manufacture of steel, that a volume 

 could, if necessary, be written to show its great strength and tenacity. 

 All that is now wanted, is a sufficiency of capital to transport the ore 

 to market, or manufacture the Iron with charcoal, in the immediate vi- 

 cinity of the "Hills," where there is a superabundance of the best water 

 power in the State ; and we ca:n see no reason why Michigan cannot 

 supply her sister States with this superior Iron at a lower price than any 

 other iron can be produced in this country. 



"Bloom Iron" can be made with charcoal in Marquette county, by wat«r 

 power, and placed on board vessel at the low price of 1 26 50 per ton 

 of 2240 pounds; and the same Iron can be sold in New York for $10© 

 per ton for the various purposes we have enumerated. 

 [, The ore being above the surface, its value can be as easily ascertained 

 as the value of a pine tree in the forest; and investments of capital in 

 this business do not nm that hazard they necessarily must run in search- 

 ing for copper and other materials beloio the surface.
