LEHIGH COAL. 
The importance and value of. this coal for manufactiring 
as well as for domestic purposes, is not genera rally known ; 
but its use is rapidly extending, it having been found equal, if 
not preferable, to other fuel for most of the purposes to 
which it has been applied. For nailing, for the rolling and 
slitting of iron, malting, distilling, evaporation of sabts, for 
steam | engines, where the furnace is properly eins ; 
Ie all these purposes it is era Shane oe erence.

lasant smell and makes a most durable fire. . Producing 
pipe or chimney can never become foul, or be 
in danger of taking fire. Neither will the misery of a smoky 
chimney ever be endured where this fuel is used. 
For blacksmiths use, it is superior to the bituminous coal 
for all general purposes, except, perhaps where a us 
hollow fire is required, for very heavy work. Some alteration 
however, is necessary in the tue (twyer?) iron. The g 
geons of the bellows ought to be placed four or five ihe 
above the level of the nose of the pipe; the back of the 
othe should be brought up slanting back, so that part 
i) e may rest on it; the hearth should be filled up to 
level with the bottom of the tue iron, and some little: 
skill is requisite: to keep the fire open, which is soon 
acquired. 
When we take into view the trouble attending ” making 
of charcoal, that not every kind of wood will answer, 
(hickory, maple, gum and chesnut being the wood generally 
used for this purpose,) the nightly watching while in the pit, 
where even in spite of every care it is often entirely con- 
sumed ; the waste and destruction it causes of timber, 
might be applied to more valuable purposes; and seat
