2. Manifold mine, south of Meadowlands. 
3. Blanche mine, Peters Cr< ek. 
4. Nottingham mine, Peters Creek. 
These four analyses show a fair agreement. The fixed carbon and 
sulphur arc moderate and the asli is low, but more variable. 
At the Ellsworth collieries four samples have been taken, the first 
from each mine being taken by the writer of this report and the sec- 
ond from each mine by Messrs. (doves and Von Borries, of the fuel- 
testing plain .

These analyses show an improvement on the quality of the coal 
farther north and west. It is fairly low in sulphur and average! 
slightly higher in fixed carbon. The proportion of ash averages about 
the same. This coal would seem to be worth coking. 
The average composition of the coal in the quadrangle, based on the 
foregoing eight analyses, is as follows:
