Anthracite Coal of Pennsylvania. 349 
grates, forges, air furnaces, distilleries, and breweries, it is 
decidedly superior to any coal | have ever used, in point of 
durability and its capacity to produce clean, sharp work. It 
contains less sulphur and slate than the Susquehannah or the 
KLackawana, but whether less than the Schuylkill I cannot 
state, except from report, having never used it. 
“Tam satisfied that more work can be. done with it, ina 
given space of iime, than with any other coal I am acquainted 
with.” 
New York, July 15, 1825. (Signed) WM. BARKER, 
“J, Thomas Barnhurst, brass founder, &c. of Philadel- 
phia, certify, that I have been in the use of the Lehigh coal 
for several years, for brazing and melting brass and copper ; 
and my experience authorizes me to say, that in brazing or 
soldering, my hands can doina given time, with one half the 
expense, three times as much work as they can with any 
other kind of coal that I have ever used. And for melting 
any kind of metal, one fire will answer the place oi eight fires 
of charcoal, at no greater expense than each fire of char- 
coal ;—that taking into view t.e great saving of expense of 
fuel, and the very great additional quantity of work my hands 
ean do with Lehigh coal mere than any other kind, | think 
it invaluable either for melting or brazing.”’

“¢T Samuel Heston, of Bucks county, have followed the bu- 
siness of a blacksmith for thirty years, and until the year 1819 
was in the habit of using charcoal and Richmond coal. Dur- 
the war I cbtained a parcel of Lehigh coal for trial, but could - 
do nothing with it and considered it a worthless article. In 
the year 1819, I made a visit to Mauch Chunk and there had 
an opportunity of seeing this coal properly used. I brought 
some of it back with me in my wagon, and have been in the 
use of it ever since, hauling it from Philadelphia a distance of 
28 miles, rather than purchase charcoal in my neighbour- 
hood. I can do more work with one bushel of the coal than 
any man can do with three bushels of Richmond coal or six 
bushels ofcharcoal. In short, I consider the discovery of 
Lehigh coal one of the most important ever made in this coun- 
try, and should hardly be tempted now to use any other if it 
were given me for nothing. WhenI went up to Mauch Chunk 
for curiosity, I had sold out all my stock, intending to move
