heating the iron, until about six months ago we were induced 
totry the Lehigh coal, and find it somuch superior to any 
other, that we now use it exclusively, and we believe there

the Lehigh at the present prices of each, as we can perform 
the same business with two tons of the latter that we could 
with eighty-five bushels of Virginia.

making it about twice as large as is common, and begin your 
fire with a little charcoal or wood at the bottom, and not let 
any dead coal get to the tue-iron and you have no difficulty, 
and ‘when you leave your fire, putin a small piece of wood
