MINING PRACTICE. 93 



Besides these, specially large sheets were distinguished as admalla 

 and urtha ; but the sizes appeared to vary at different mining cen- 

 tres. The writer was informed by Mr. W. H. Paschoud, Manager of 

 the Singho division of Messrs. Chrestien & Co.'s mines, that the native 

 miners still employ the terms manjhla and sanjhla for inter- 

 mediate sizes, the ordinary adjective bara being used without 

 special limitations for large specimens, whilst the smaller grades 

 were merely known as chkota, and the waste, raddi. 



Prices are extremely variable, and the market, being a comparatively 

 small one, is sometimes subject to considerable artificial variations 

 according to the wishes of the larger producers. The following 

 quotations from recent sale reports of the Indian Mica Company will, 

 however, give an approximate idea of the value of the mineral.
