to a certain extent replace, or at any rate help to economize, supplies 

 of nickel ; the two metals are very similar in their properties, and 

 for some purposes cobalt is actually superior ; cobalt alloys, such as 

 stellite, are already used for a good many purposes.

Note. — In the large sheet-map of the British Empire each British possession is 



coloured pink, and the names of the various minerals found are printed on

It is hardly necessary to enlarge on the importance assumed by 



tungsten in the last four years as a munition of war. Until 1914 



the tungsten metal industry was almost entirely in German hands, 



although the greater part of the ore was obtained from the British 



Empire and the United States. For a time Burma was the largest 



producer, but is now surpassed by the United States. Some 



countries already show signs of exhaustion, partly owing to 



improvident methods of mining in the last four years, but it seems 



probable that certain newly opened-up localities, such as China, 



Korea, and Manchuria, will be able to yield a good supply for many 



years to come. In addition to Burma, the Empire also possesses 



important tungsten resources in the Malay States, Australia, and New
