on them, are placed two other like cylinders, making 

 six cylinders in the whole, all made of the same mate- 

 rial and being of the same dimensions. 



The fire-place being situated under the hither ends 

 of the two lower cylinders, the flame runs along under 

 them to their farther ends, where it passes upwards 

 and comes forward between the upper sides of the two 

 lower cylinders, and the lower sides of the two cylin- 

 ders immediately above them. Being arrived at the 

 front wall of the brick-work, it there rises up again, and 

 then passes along horizontally between the two middle 

 cylinders and the two upper cylinders, till it comes to 

 the back wall ; and, passing up by the farther ends of 

 the upper cylinders, it comes forwards horizontally, for 

 the last time, in an arch or vault of brick-work which 

 covers the two upper cylinders. Being arrived once 

 more at the front wall of the brick-work, it there enters 

 a canal (furnished with a good damper) by which it 

 goes off into a neighbouring chimney. 



These cylinders are confined in their places by being 

 placed in pairs, over each other, between two parallel 

 vertical walls, which are built just so far asunder as to 

 admit two cylinders, placed horizontally by the sides of 

 each other ; and the flame is prevented from finding its 

 way upwards between the two cylinders which lie by 

 the sides of each other, or between the outsides of those 

 cylinders and the sides of the vertical walls with which 

 they are in contact, by filling up the joining between 

 them with good clay, mixed with small pieces of fire- 

 bricks. 



The farther ends of all the cylinders are closed up, 

 and all the tubes which are necessary for the admission 

 of water and for the passage of the steam are fixed to
