CARBONIFEROUS OF CAPE BRETON—GILPIN. 35 
In my next paper I purpose giving analyses of the seams of 
the various coal districts, and of their ashes, their gas values, etc. ; 
and such information as I can gather about the extent, nature 
and value of the various beds of iron, copper and lead ores, and 
of the other minerals of the various sub-divisions of the Carboni- 
ferous of Cape Breton.
