The coal is here again underlaid by whitish sandstone for 

 about thirty feet, or to the water's edge. Nearly opposite the 

 exposure, on the south side of the river, the seam appears at in- 

 tervals in the bank, at a height of about forty feet above the 

 water, for at least a quarter of a mile. It is affected by a series 

 of light undulations. 



The natural exposures serve to prove the continuity in good 

 workable thickness of the coal deposit over a tract of country 

 several miles in extent, and its nearly horizontal attitude and 

 moderate depth below the surface of the plains, would enable it 

 to be proved by boring at a small expense over any desired area. 



In texture, this coal is not so firm or well adapted for trans- 

 port as tliose of the localities previously described, but in com- 

 position appears closely to resemble that of Horse-shoe bend. 



The following are analysis of the fuel from this place ; the 

 first from a specimen obtained by Prof. Macoun, the secoad from 

 one collected by myself, and probably not subjected to such pro- 

 longed desiccation : —

Three coal bearing localities on the head waters of the Oldman 

 River appear to be of suflScient importance to obtain notice at 

 the present time, but as the country toward the base of the
