250 COAL, DYES 



the actual existing deposits. . . . An enormous proportion of 

 this coal is, of course, at present inaccessible, but undoubtedly 

 railways will be provided as soon as it becomes profitable 

 to work the seams, and meanwhile it is obvious that one of the 

 essential elements of industrial enterprise exists in abundance.' 1 



There are also deposits of coal in many parts of Rhodesia, 

 the chief mines at present worked being at Wankie, to the 

 north-west of Buluwayo. 



Coal is also being mined in Nigeria. 



In India, the principal coal-mines are in Western Bengal, 

 in the Damodar Valley ; and there are also mines in the 

 Narbada and Godavari Valleys ; in the hills of Chutia Nagpur ; 

 and in the north-east of Assam. The output compared with 

 ours in Britain is small, but it has increased in recent years. 



To sum up, then, Britain's stores of coal, though vast, are 

 not inexhaustible ; they are variously estimated as sufficient 

 to last from three to five hundred years. 



In substitutes for coal, such as petroleum and water-power, 

 she is not rich ; the idea of using the tides as a source of 

 power is fascinating and a project is at present under the 

 consideration of the Government. 



In other parts of the empire there are immense deposits 

 of coal, for the most part undeveloped, but representing 

 a possibility of enormous economic power in the future ; 

 while Canada and New Zealand possess, in addition to coal, 

 vast stores of potential energy in their unlimited supply of 

 water-power.
