LEHIGH COAL. 
The importance and value of this coal in various 
manufactures, as well as for domestic use, are now be- 
ginning to be more generally known. Its use is in conse- 
quence rapidly extending, it having been found, for 
most of the purposes to which it has been applied, 
reatly superior to all other descriptions of fuel. 
For melting metals, for nailing, for rolling and slit- 
ting of iron, for malting, distilling, burning lime, baking 
and evaporating salts, it is entitled to a decided prefer- 
ence; and for various other uses in the arts it is confi- 
dently believed that, on trial, its advantages will be 
found to be equally great. Of all known species of fuel, 
it makes the most durable fire, creating an intense but 
regular and steady heat, without smoke or unpleasant 
smell, and producing no soot. The pipe or chimney 
therefore can never take fire, neither will the misery of 
a smokey chimney ever be felt where this coal is used. 
For blacksmiths it is superior to the bituminous coals 
for all general purposes. But some alteration is neces- 
sary in the tue-iron. The gudgeons of the bellows ought 
to be placed 4 or 5 inches above the level of the nose 
of the pipe. The back of the fire place should be 
brought up slanting backwards, so that part of the fire 
may rest on it. The hearth should be filled up nearly 
level with the bottom of the tue-iron, which should be 
1% to 1% inches diameter, and a little art, which is 
soon acquired, is necessary to keep the fire open. 
Furnaces for burning this coal should be so con- 
structed as to free themselves from ashes. For this pur- 
pose the bars of the grate should be made smaller at 
the bottom than at the top where the coal rests, and 
should be placed not less than seven eighths of an inch 
apart, giving the grate or stove a strong draught of air. 
The following certificates, selected from a great num- 
ber which might be given, will confirm the statement 
above made of the great value of this fuel.

prietors of the great Lehigh Coal mine, by Messrs. 
White and Hazard, when owners of an extensive wire 
factory, and rolling and slitting mill, at the falls of 
Schuylkill, five miles above Philadelphia— 
“We have used the Lehigh coal, and in the heating 
of bar iron for rolling, we find it to contrast with 
Virginia as follows: — 
With Lehigh coal, three men will roll ten cwt. of iron 
for wire, and burn five bushels of coal per day of 12 
hours. 
dihe twages are) pw apc ecny oe 4 00 
Five bushels of coal at 90 centsis . . . 4 50 
$8 50 
With Virginia coal it takes ten bushels to heat five 
cwt. of bars, which is all the three men can do with 
this coal in one day. 
The wages as above is four dollars per day, but 
rolling but five cwt. a day, it will take two days to roll 
ten cwt. making the wages for that quantity .. 8 00 
Suppose the coal to cost only 22 cts. per 
bushel, 20 bushels would be.........- 0 50 
$8 50 
It follows that to us Lehigh coal at ninety cents is 
equally cheap as Virginia coal at two and a half cents 
per bushel.”

“We the undersigned do certify that we are now 
using the stone coal for heating hoops for cut nails, 
and find it to exceed any other coal or wood fire for 
this purpose. 
Our practice is, in the morning when we leave the 
shop for breakfast, to throw a quantity of coal on the
