DESCRIPTION OF A STOVE. 0(J 



The confiruction of this ilove is neither difficult nor expen- Materials of 

 five. For the outfide nothing is wanted but Dutch tiles, fuch is con ft ru a e <j. 

 as are ufed for common ftoves, that is to fay thin in the middle, 

 and having a border all round, which ferves to give them more 

 lability. They are fixed in like manner by a band of metal. 

 The hind part may confift entirely of bricks. The vafe placed 

 on the flab of marble or ftone, which covers the ftove is a 

 mere ornament. 



If it be thought proper to have no heat openings, all the The heat opaa* 

 interior ftrudure may be made of bricks of proper fizes, laid om j ttec i, y 

 with loamy earth moiftened, and fet on edge for the circu- 

 latory pipes, without any iron except a caft plate over the fire- 

 place, and a door and frame in the ufual manner. 



The expence of the heat openings however confifts only in Theexpencc 

 r . , . , , ,, however not 



four cait iron plates with tongues and grooves to form the com- grear# 



partments reprefented at tig. 7. All tiie reft is done with plate How are they 



iron, bent round and rivctted, which, when once enclofed in ma 



the mafonry, will not admit the efcape of the air. 



Call iron plates with grooves are well known, fince Frank- Subftitutes for 

 lin's Hove* have been adopted. If it were found difficult to p lates<( 

 procure them, their place might be fupplied in two ways. 

 Firft by portions of pipes of cafe iron, which might be placed 

 vertically fide by fide, ferving as the infide walls of the fire- 

 place, and communicating with each other by little channels 

 at top and bottom formed in the mafonry. Secondly, by com- 

 mon plain caft plates, foft enough to admit of being bored, Co 

 as to rivet on bent flips of plate iron, which would perfectly 

 anfwer the purpofe of the tongues and grooves. As thefe 

 would never be expofed to the action of the flame, there is no 

 reafon to fear their calling. The latter of thefe two methods is 

 obvioufly the mod advantageous, as it occupies lefs room, and 

 yet affords more furface to receive the action of the heat, and 

 communicate it to the circulating air. 



In concluding my defcription of this ftove I ought not to Its utility con- 

 omit faying, that nearly two years experience has convinced ^^l^J^nce 

 me of the good effects of its proportions. 



It is placed in a room fronting the north, the floor of which Account of to 

 meafures 47 metres fquare (about 12 toifes j) and which is e 

 42.5 decimetres (13 feet) high.
