on Coining Silver into Rupees.

The blanks when cut out pass to an officer whom we call the Adjuster 
whose duties are very important. 
After being slightly cleaned the blanks 
are individually weighed in Automatic Machines, the light blanks are re- 
turned to the melting pot, while those that are too heavy have their weight 
reduced. This used to be done by hand, but we have recently made a 
machine which deals satisfactorily with about 1500 blanks an hour. 
As the 
farther processes of coining reduce the weight of the blanks, an allowance has 
to be made here for this reduction, and it is part of the adjuster’s duty not only 
to keep his machines in order and see that each blank is within the remedy 
allowed, but further to check the weights of the bags (each containing 2000 
blanks) and see that each bag is within the much narrower limit laid 
down for his guidance, and that finally even then they are not all on one 
side so that the error would accumulate.

The proportion of light and heavy blanks beyond remedy is about 
what has now for many months been usual: the Tale of Blanks sent on is 
smaller in proportion, and Ihave not thought the percentage worth giving. 
Of course it includes heavy blanks reduced, but only whole bags are sent 
on, and thus not only has the percentage sent on been smaller but it is 
more regular than usual: I believe too that the weight is more regular. 
The experiments were not sufficiently extensive to show the working 
of the machine for reducing blanks, but the following data will show this 
and give a comparison with the old method of filing by hand. 
In December 1878, 283,639°9 Tolahs of blanks were reduced 
The recovery was 1243'4 Tolahs of particles worth 1173-61 Rs.,
