NEW STOVE. at 
’ Every utenfil, however properly contrived to ferve its 
purpofe, requires fome practice before it can be ufed adroit- 
ly. Put into the hands of a man for the firft time, a gim- 
blet or a hammer, (very fimple inftruments) and tell him 
the ufe of them, he fhall neither bore a hole or drive a nail 
with the dexterity or fuccefs ot another who has been a little 
accuftomed to handle them. The beginner therefore in 
the ufe of this machine, will do well not to be difcouraged 
with little accidents that may arife at firft from his want 
of experience. Being fomewhat complex, it requires as 
already faid a variety of attentions; habit will render them 
unneceflary. And the ftudious man who is much in his 
chamber, and has a pleafure in managing his own fire, 
will foon find this a machine moft comfortable and delight- 
ful. To others who leave their fires to the care of ignorant 
fervants, 1 do not recommend it. They will with difi- 
culty acquire the knowledge neceflary, and will make fre- 
quent blunders that will fill your room with fmoke. It 
is therefore by no means fit for common ufe in families, 
It may be advifeable to begin with the flaming kind of 
ftone coal, which is large, and, not cakinz tozether, is not 
fo apt to clog the grate After fome experience, any kind 
of coal may be ufed, and with this advantage, that no fmell,. 
even from the moft fulphurous kind can come into your 
room, the current of air being conftantly into the vafe, 
where too that fmell is all confumed. 
The vafe form was chofen as being elegant in -itfelf, and 
very proper for burning of coals: Where wood is the ufual 
fuel, and muft be burnt in pieces of fome length, a long 
fquare cheft may belub/tituted, in which A is the co-. 
ver opening by a hinge behind, B the grate, Cthe Pi? 
hearth box with its divifions as in the other,.D the 
plan of the cheft, E the long narrow grate. This 1 have 
not tried, but the vafe machine was compleated in 1771, and 
ufe d by me in London three winters, and one afterwards: 
in America, much to my fatisfaction; and I have not yet 
thought
