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 
— ite . rolling, we find it to contrast with Virginia Coal: 
as 
With Lchigh Coal, ‘three men will roll ten ewt. of iron 
for wire, and not five bushels coal per day of twelve hours. 
The wages 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 da 8 50 
he wages as above, is four dollars per day, but 
tolling but five ewt. a day, it will take: ee con ei ges 
ten cwt. making the wages 8 00 
coal to cost only: he per ee ook. 
tupsity bushels would be 00 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. 
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 mat- 
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 
ie bere. clown; no smoke or smell nie: uae 
or any dirt flying pas stirred, which is a oem aesine 
to all wees coal for any use. : :
