Tofield, near Edmonton. The results, calculated to a moisture-free 

 basis, showed a close agreement with those obtained from the Shand 

 mine coal, thus indicating that the results of this investigation are 

 generally applicable to low grade Canadian lignites. 



Acknowledgments. 



The above investigation was carried on in the Fuel Testing 

 Laboratories of the Mines Branch of the Department of Mines, at 

 Ottawa, where a further investigation along the lines indicated is
