A mine could scarcely be more favorably situated for access than 

 this ; the coal comes to the edge of the ravine and has a slight dip 

 to the southeast. 



It can either be rolled down to the river's edge, and transported 

 by boat to Medicine Hat, or drawn up an incline to the prairie level 

 and taken by train to points east and west ; the latter plan has 

 been followed. During the past year active work in the mines at 

 Lethbridge has affected operations at this place. It is not likely 

 after this that Medicine Hat coal will be used much beyond that 

 locality ; for it is found that coal from localities nearer the mountains 

 is superior to that obtained farther east. 



Before the opening up of other mines the coal from Medicine Hat 

 was used in considerable quantities in Winnipeg. It is easily 

 kindled, burns with an intense heat and leaves no clinkers. Con- 

 sumers considei'ed that If tons were equivalent to 1 ton of anthracite. 

 The following analysis taken from the report of the Geological 

 Survey gives the composition of this coal.
