[Concluded from Page 170.]The superior economy of the furnace system of coking, when carriedout on a large scale, has led to its universal adoption by railway com-panies, and other extensive manufacturers; and, consequently, the moundprocess has of late years beon disregarded. Figs. 1 and 2 of our en-gravings, represent the principal arrangement which has found favourat the ironworks of this country. In order to economise both brickworkand heat, several furnaces are built together; in this case there are four,the last one being broken away in our view. Each furnace is a rectan-gular space with an arched top, its dimensions being 10 feet from frontto back, 12 feet wide, and 10 feet high. The linings are of firebrick, Fig. ~~~ | | —-_; ~
