® at each end EE. From one end rifes a pipe or flue 
‘¢ about four inches diameter, on which other pieces of pipe 
*¢ are fet, which are gradually contracted to D, where the 
“ opening is but about two inches. Thofe pipes muft to- 
** gether be at leaft four feet high. B is an iron grate. 
“°F F are iron handles guarded with wood, by which the 
** {tove is to be lifted and moved. It ftands on three legs. 
*¢ Care muft be taken to ftop well all the joints, that no 
“ {moke may leak through. 
‘* When this ftove is to be ufed, it muft firft be carried 
“¢ into the kitchen and placed in the chimney near the fire. 
“© There burning wood muft be laid and left upon its grate 
«till the barrel C is warm, and the fmoke no longer rifes 
“eat A, but defcends towards C. Then it is to be carried 
“into the room which it is to warm. When once the 
“ barrel C is warm, frefh wood may be thrown into the 
*¢ veffel A as often as one pleafes, the flame defcends and 
“« without fmoke, which is fo confumed that only a va- 
“ pour pafles out at D. 
« As this vapour is unwholefome, and affects the head, 
“ one may be freed from it, by fixing in the wall of the 
‘“« room an inverted funnel, fuch as people ufe to hang over 
“lamps, through which their fmoke goes out as through 
“achimney. ‘This funnel carries out all the vapour cle~ 
“ verly, fo that one finds no inconvenience from it, even 
“¢ though the opening D be placed a {pan below the mouth 
“ of the faid funnel G. The neck of the funnel is better 
‘“¢ when made gradually bending, than if turned ina right 
* angle. 
“ The caufe of the draft downwards in the ftove is the

“a refifting paflage at the grate B, of five inches, and 
“one at D, of two inches, which are much too weak 
* to drive it back again ; befides, A ftands much higher
