•semi-bit umlr.'O us coal, that from some recent developments, treat Stokes- 
burg, Stokes county, containing about ten per cent of volatile matter. 
140, Lignite ok Brown Coat.. 
Frequently met with in the marl beds of the eastern counties, and in 
Trias ot Granville county,* on Tar river. 
This completes the list of minerals thus far found in the State of North 
Carolina, which necessarily form only the basis of a more complete work 
-on the Mineralogy of the State, 
Many of the species, which are .mentioned in the above, were deter- 
mined by qualitative, chemical analysis, the nature of others can be 
accurately established only by very minute quantitative analysis and 
-crystallographic determinations, both ot which, you are aware, consume 
much time. However imperfect the above work may be, I believe it to 
be sufficient to show the very great richness of both interesting and 
^useful minerals and ores, and that their development will place North 
•Carolina in the first rank of the mineral producing States. 
All of which is respectfully submitted,
