dish iron ; and 3rd, imparting a certain quality, (the cause of which is 
not yet understood), which adapts the iron especially for the manufacture 
of steel." “ The titanized iron is found to be exceedingly strong, and is 
used in Europe for armor plates, commanding three times the price of 
ordinary pig iron.” Muchet’s steel is made from titaniferons ores, for 
the manipulation and utilization of which, in the manufacture of steel 
and high grade iron, that gentleman has taken out no less than 13 patents 
in England, where Norwegian ores containing 41 per cent, of titanic acid 
are successfully employed, as stated by Dr. Lesley on the authority of 
Osborne. 
“ There is no question that titanium in iron ore favors the production 
of iron peculiarly suited to conversion into steel. The English steel trade 
has always largely depended on Swedish iron ; and I believe that the 
titaniferons ores of the United States, (and they are far from abundant), 
will become annually more and more valuable, on account of the demand 
increasing for the best iron for steel making purposes.” 
Dr. Lesley refers also to the fact that the ochre-beds already described 
as accompanying the iron ore range, furnish a superior flux for these ores. 
“The ochre must become a fluid double-silicate, without robbing the ore, 
and will carry off the excess of titanic acid.” 
An analysis by A. A. Fesquet, which he gives of “this ochre, which 
forms large beds on the outcrops of the more ferruginous felspathic rocks,” 
is added : 
Sesquioxide of Iron, 19.43 
Silica, 34.12 
Alumina, 33.21 
Water, &c., &c.,. 13. 24; 
So that this ochre will furnish more than enough oxide of iron for the 
slag, and will therefore increase the run of iron. 
I add a few of Dr. Lesley’s general conclusions as to the quality, quan- 
tity, uses and value of these ores. 
“The quality of ore, although various and suited to at least two 
branches of the iron manufacture, is of the very first rate — none better 
in the world.” 
“The soft ores will smelt easily and make magnificent ijj^p ; absolutely 
the very best ; perfectly malleable, tough and strong.” 
“The hard ores will command a high price for puddlers’ linings; will 
be in demand for mixing with poorer ores of other regions,” as are those 
of Canada and the Champlain ; “and will have an especial value for the
