livered at my mill. But with from 7 1-2 to 8 bushels of 
Lehigh coal I roll as much iron as would require 13 
bushels of Virginia, and the work is done in from two 
to three hours less time; so that my profit by using the 
Lehigh is 4 dollars 55 cents per ton, or | dollar 75 cents 
per day. This however is not all the advantage—my 
foreman will work with Lehigh coal for lower wages 
than with Virginia, the trouble is so much less; for in- 
stance on Monday morning the fire is made with a little 
wood or half a bushel or more of Virginia coal to start 
it, and it can be got ready for a heat in about one and a 
half or two hours; when once in order you have nothing 
to do but add coal, heat after heat—no cinder or other 
trash to take out until the day’s work is done—then 
rake up the fire by pushing to the back all the coal that 
remains in the oven, shut down the damper, and in the 
morning you have fine live coals, the quantity very 
little diminished during the night; from Monday to 
Monday, no wood or other fuel wanted, and your 
oven always warm in the morning. Any one acquainted 
with the business can compare this with the trouble 
of Virginia coal, and after all, you cannot make so 
regular a heat as with Lehigh, but are apt, without a 
great deal of care, to burn the iron in one place and 
not have it hot in another. My furnace was constructed 
to burn Virginia coal: I made no alteration in it, ex- 
cept taking some of the bars out of the grate, so as to 
make the spaces between the bars wider. 
This statement, which may appear partial, is given 
only for information. I have no interest in the Lehigh 
company, other than that of getting a regular supply 
for my business of this excellent fuel.”

“We have used the Lehigh coal several years past to 
heat bar iron for our rolling mill at Bridgetown, Cum- 
berland county, New-Jersey; prior to the introduction 
of this, we used the Richmond coal for the same pur- 
pose, and from experience thus obtained, we are satis- 
fied that for this purpose, one bushel of the former is 
worth at least two of the latter.”

“The quantity of Lehigh coal in Philadelphia here- 
tofore, not being equal to the demand, I have not been 
able to obtain sufficient for my use, and have burned it 
but seldom in the rolling mil., but constantly for several 
19¢c 
years in the nail factory. I shall use it in preference to 
any other fuel when I can be supplied, being well con- 
vinced of its superiority. I have had heated, for rolling 
into hoops, 11 tons of bar iron, with 33 1-2 bushels of 
your coal, when it would require nearly double that 
quantity of Virginia coal, or about six bushels to the 
ton. In the nail factory we consume about one bushel 
and three pecks of Lehigh coal to heat a ton of nail 
plates. As it requires no charring, is very durable, and 
the heat intense, much time is saved in the use of it. A 
fire made in the morning lasts till noon, then replen- 
ished, endures the rest of the day.”

“We are of opinion that Lehigh coal is much to be 
preferred to wood, as fuel for drying malt, being more 
economical, requiring less room for storage, and less at- 
tention whilst burning, from its steady heat and great 
durability. The danger of accidents from fire is so much 
diminished by the use of this coal, that 7t alone would 
be sufficient to give it a decided preference.” 
DAWSON & MORRISON. 
“From considerable experience I have found the 
Anthracite from Lehigh much superior either to the 
Rhode-Island or Kilkenny, (Ireland).”

“For melting brass the Lehigh coal is preferable to 
any other; for one ton of Lehigh will do as much work 
as 200 bushels of charcoal for melting, beside is not half 
the labour in attending the furnace; and likewise for 
soldering our work. One person can do more than 
double the work with the Lehigh than they could with 
charcoal on the forge, and I find a great advantage in 
using it at the rolling mill, for heating the oven in which 
we neal the brass for rolling, for two fires will serve for 
the whole day. 
I therefore think it is the cheapest by one half.”

“Having a mill for rolling and slitting of iron, we 
have for many years been in the habit of using the Vir- 
ginia coal for heating the iron, until about six months 
ago we were induced to try the Lehigh coal, and find it 
so much superior to any other, that we now use it ex- 
clusively, and we believe there is a saving in the ex-
