reconcile them to the experiment, we proceeded to charge 
the furnace with alternate layers of ore, charcoal, and Rhode 
of charcoal alone, and that it was also of a better quality : it 
much oftener than before. This satisfied every person con- 
am not aware that any fair experiments have been yet 
made by the iron manufacturers, to introduce the use of this or 
which has been proved to contain 94 per cent. of pure carbon,

ed that it would not bear the blast of the bellows; but so 
far from this being the fact, 1 am willing to assert, from ex- 
perience, that it bears the blast better than charcoal, and 
that this is one of its essential qualities ; as, by this means, 
while the lighter kinds of charcoal are dissipated by the blast, 
without being allowed to come into contact with the ore, 
this coal, not being driven off by the wind of the bellows, re- 
mains longer in a state of ignition in contact with the ore; 
thus producing much more metal from a given quantity of it, 
than can be obtained from charcoal alone. be un- 
candid in me not to state that, in the experiment which I wit- « : 
nessed at the Kingston furnace, it was observed that -smalt 
pieces of coal ran out at the opening from whence the metal - 
was drawn, flowing on the surface of the slag or scoria ; but
