IRON MANUFACTURE. S\337/ 
generally to meet some special call, and may be of any quality de- 
sired, running from the purest Bessemer pig to iron made largely 
from mill cinder for use in rolling-mills. 
An analysis of an iron made from Ohio ores in part is given, from 
Cherry Valley Iron Works, Leetonia:

At Leetonia, in Columbiana county, are the works of the Grafton 
Tron Co. and Cherry Valley Iron Works. These latter make, from the 
New Lisbon kidney ore and Lake ore and mill cinder, with Connells- 
ville coke, the American Scotch pig, already alluded to in a former part 
of the report. The works are provided with Pollock stoves, and with 
three blowing engines. The Grafton Iron Co. has two stacks, one just 
built; the hearth of their new furnace is built entirely closed, being 
merely provided with an opening through which the iron is to be tapped, 
the slag discharge being entirely independent of this opening. The 
furnace has six tuyeres, one over the tap-hole. The furnace is provided 
with two engines, one 84 in. by 4% ft., and one 66 in. by 4 ft., running 
at 40 revolutions per minute; each furnace has two Player pipe-stoves ; 
the blast is heated to 900 degrees, as shown by pyrometer; the works 
have a foundry in which the tuyeres and other castings are made. 
The use of raw coal simply is perhaps best shown in the furnaces 
around Jackson, Ohio, and in the Hocking Valley. Several of these 
Jackson furnaces are outlined on plate 2, most of these using little or 
no mixture of coke. The table on page 541 gives figures from several 
of these furnaces, illustrating the average charge of ore, coal and lime- 
stone. Of the works at Jackson, the Tropic furnace is provided with
