this is sie explained, by referring to the statement which I 
_ have given of the chemical properties of the coal, which only 
consumes on the surface exposed to ignition in oxygen.. e 
largest pieces, therefore, remaining in contact with the metal, 
were only partly consumed, and falling down with it to the

urge on the iron manufacturers to abandon their prejudices, 
and to turn their attention.to the expediency of the use of this 
and 
fossil coal, so abundant in their country, so favourably 
sitsated for their purpose. Without doing so, iron mine

While he coal fields at Rhode-Island were extensively 
worked, an immense quantity of small coal had accumulated 
in the neighborhood of this mine, which was unfit for the 
market, and was therefore considered as useless ; it ought not, 
however, to have escaped notice, that this — coal was 
_ adapted to many useful purposes, being very similar to what 
is called culm in England and Wales, which is pacrite and 
extensively used in the burning of lime and brick. One of 
the most favourable situations that could be wished, for the 
extensive use of this small coal in the burning of lime, oc- 
curs within a short distance from the mines, and with the ad- 
vantage of water carriage ; ree | refer to the valuable Ceci of
