IRON MANUFACTURE. 505 
connection with the rolling-mill of the company. The other works 
along the Ohio river in this district are the Monitor furnace, a small 
charcoal furnace, which is peculiar in being built with an iron mantle 
instead of the customary stone stack seen elsewhere in this district ; 
it has been before mentioned as employing a kiln for roasting ore; and 
the Hanging Rock furnaces of Means, Kyle & Co. This company is 
building at present, in addition to the furnaces they already have, a 
large stack of 16 ft. bosh by 72 ft. height, of which the lines are given 
in plate No. II. 
The furnace is to be equipped with the Gjer kilns spoken of before. 
The charcoal furnaces of the district lying back from the river, and 
situated through Lawrence, Scioto and Jackson counties, will be found 
given in name and capacity in the table of the furnaces of the State on 
pages 456-458. In regard to the outlines of the furnaces of the dis- 
trict, plate I, annexed gives as nearly as could be obtained the interior 
forms of a number of the best known of these charcoal furnaces. 
The following tables give the dimensions of the same furnaces 
from which the sketches were made, also the capacities, as closely as 
could be calculated, of each furnace, it not having been possible to get 
in all cases exact measurements, but sufficiently close approximations 
were obtained to give nearly the volumes:
