14 Anthracite formation of Wilkesbarre, &c. 
The following statement taken from my book, will exhibit 
in a clearer light, the value of Lehigh coal : 
Smith book account and wrought iron on hand, 
for the month of January, eighty-six days work done $211 
Charcoal used in forging the same, three hundred 
and seventy-five bushels, at $12 per hundred bushels 45 
Smith book account and wrought iron on hand, 
from 1st February to the 25th March, one hundred 
and seventy-seven days work done 733 
Charcoal used, two hundred and seventy-five 
bushels, deduct for same in proportion for January, 
as the work was similar 129 
Seventy-five bushels of Lehigh coal used in forg- 
ing the above, $604 worth of work, at $1 per bushel 604 
Charcoal necessary to have done the $604 worth 
of work, agreeable to the experiment of January, 
one thousand and seventy-two bushels, at $12. 127 
From which deduct $75, the price of the Lehigh 
coal 75 
Leaving the balance in favour of the Lehigh coal 
of 52 
Tt is my firm belief, that the time gained is worth more 
than the whole price of the coal.

N. B. One of my journeymen, who was the most adverse, 
is now using the Lehigh coal at Boyertown, Berks county, 
at $75 per hundred bushels, in a neighbourhood where 
charcoal can be purchased for one tenth of the sum.

I have, for two months past, made use of stone coal in 
my distillery, and am much pleased with it. I have ascer- 
tained that three bushels of coal (with a little dry wood to 
kindle) is sufficient to run my singling still six times, my 
doubling still once, and boil all the water for mashing, &c.
