Anthractie Coal of Pennsylvania. 1 83, 
(what indeed accords with my recollection as to the combus- 
tion of this coal, when I saw it burning in Newport, eighteen 
years ago,) that it would burn with intense ignition, but with 
very little flame. 
Itis obvious that the comparatively abundant flame of the 
Pennsylvania anthracite must fit this fuel for some important 
purposes, (principally for varieties of furnace operations,) 
which are very important in the arts—ihus combining the ad- 
vantages ofhoth kinds ofcoai. tis well known that the most 
intense heat is not produced by the bituminous coal, until it 
has been coaked—that is—the volatile part, including the 
gas and bitumen is driven off by a smothered heat, and the 
purer carbonaceous part is obtained by itself. Now the an- 
thracite, properly burned, produces always the intense heat ot 
coak, and if it give at the same time the effects of abundant 
flame, it is obvious that it must answer in reverberatory and 
other furnaces, which require flame, such as the cupola fur- 
nace, &c. ‘TPhatit is actually so applied, in the arts, will ap- 
pear farther on, in the testimonials of artists which we shall 
have occasion to cite. In domestic economy, both the Le- 
high and the Schuylkill coal are applied with great advantage, 
both in parlour grates, and inclose stoves, for warming a part- 
ments, as well as in cooking. 
My own experience is limited chiefly to thestove or furnaee,* 
which. is constructed to stand in a hall or entry, orin some smalt 
apartment or recess, and it warms the contiguous apartments 
im consequenee of the revolution in the atmosphere of the 
rooms, arising from change of specific gravity, the colder air 
going to the stove, to be warmed, and then ascending and dif- 
fusing itself around,—thus giving place to more cold air, and

stove which stands ina small entry between the family par- 
lourand the office, effectually and agreeably warms both these 
apartments, and the connecting passages, and in a great 
measure warms the two chambers and the passages immedi- 
ately above. ‘The parlour is 22 feet, (24 including recesses,) 
by 18 feet, and the office and passages 20 by 16, the height 
of the whole is 91 feet. The stove or furnace which warms 
these apartments is constructed of Russia iron and lined, in 
the part exposed to the fire, with fire brick. Its diameter
