Titaniferous Iron from the Rideau Canal is quite extensively 
used in the furnaces of Ohio and it is claimed with profitable 
results. It is, however, here combined with a very largely 
preponderating percentage of other ores. 
Titaniferous ores are also found abundantly in other coun- 
tries than ours. In Norway vast beds of ore of this charac- 
ter exist, and unceasing efforts have been made for the last 
half century to smelt both in Norway and England. It 
must be said, however, that up to the present time all these 
trials have resulted in failure, except where this ore has been 
used in connection with a much larger quantity of ore free 
from Titanium. 
The great deposits of Iron ore discovered by Dr. Hayden 
on the Cling-water, in Wyoming, contain twenty-three and 
one half per cent. of Titanic Acid, a quantity probably sufli- 
cient, without an improvement of our processes, to prevent 
the use of this ore in the manufacture of iron. 
In New Zealand large quantities of Titaniferous ores are 
said to occur, and there too, efforts to utilize them have been 
unsuccessful. 
‘; Titanium Iron ore not only renders them extremely refrac- 
tory, but when they are smelted the resulting Iron is very 
hard. Experiments made by Shoenberger & Blair, of Pitts- 
burgh, showed that puddled Iron containing any considerable 
quantity of Titanium is so hard as to fly like glass in the 
shears.
