The space g has another use; it isolates the fur- nace from the wall, and protects the wine-cellar on the other side; /i is a temporary iron plate intended to push the fuel more towards the pipes, likewise to try the effect of more intense combus- tion at one point;—this is attained by limiting the supply of air to the space only between two of the bars of the grate; i is the aperture for the supply of fuel. In order to make the furnace air proof, all its openings have double doors, the outer of which have sand-joints; this is shown clearly in Fig. 4; the frame which receives the lid having a deep groove going all round, filled with sand, into which a projecting rim on the cover is sunk. The inner doors have a piece of talc inserted in each, to admit a view of the fire without the necessity of lifting the door off*.
