10 Anthracite formation of Wilkesbarre, &c. 
Certificate from Messrs. White & Hazard, proprietors of 
the extensive Wire Manufactory and Rolling and Slitting 
Mill, at the falls of Schuylkill, five miles above Philadel- 
phia. 
We have used the Lehigh Coal, and in the heating of 
bar iron for rolling, we find it to contrast with Virginia Coal 
as follows : 
With Lehigh Coal, three men will roll ten cwt. of iron 
for wire, and burn five bushels coal per day of twelve hours. 
The wages are $ 4 00 
Five bushels of coal, at ninety cents, is 4 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 8 50 
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 23 cents per bushel, 
twenty bushels would be 00 50 
$8 50 
It follows, that to us, Lehigh Coal at nenety cents, is 
equally cheap as Virginia Coal at two and a half cents per 
bushel. 
WHITE & HAZARD. 
Whitestown, November 1814. 
Having made a trial of the Lehigh Coal, at the Pennsyl- 
vania Bank, in the large stove, I found them to answer for 
that purpose exceeding well—they give an excellent 
heat and burn lively. It is my opinion they are nearly equal 
to double the quantity of any other coal brought to this mar- 
ket for durability, of course less labour is required in attend- 
ing to the fire—they require a strong draught. 
My opinion is, they will be found cheaper than wood ; 
they burn clean; no’smoke or smell of sulphur is observed, 
or any dirt flying when stirred, which is a great objection 
to all other coal for family use.
