probably because some mechanical treatment might be necessary to 
separate these small pieces from small pieces of foreign matter. It is to 
be noted that the worst offenders in this waste of smalls are those opera- 
tors who can obtain large quantities of ore in large pieces. Operators 
with properties that turn out inferior grades of ore only, do often stack 
these smalls and seem to be able to find a market for them. Further, at 
many even of the best deposits, a certain proportion of the ore breaks 
down into powder during excavation. This applies particularly to those 
deposits in the Central Provinces in which there is any ore consisting 
entirely or almost entirely of granular bra unite, without any psilomelane 
as cementing material. Kandri is a good example of a deposit in which 
a lot of the ore breaks down into powder on quarrying. All this is 
wasted. The same applies to deposits in which there is a con- 
siderable proportion of pvrolusite, such as some of those of Vizagapatam, 
and many of those of Mysore. In some cases pyrolusite has been bagged 
and sold, as at Kodur in Vizagapatam.. and Hoshalli in Mysore. But in 
the majority of cases this pyrolusitic ore is stacked in such lumps ar 
can be obtained, all that breaks into powder during quarrying being 
lost. Such ore if exported in the unbagged condition must then inevi- 
tably loose greatly in weight owing to powdering at every transhipment 
or dumping. My opinion is that such soft ore should be bagged at the 
mine, and that when a large amount of ore breaks down into powder, 
some attempt should be made to recover this by some means of washing 
the dust and concentrating it ; this applies especially to such a deposit 
as Kandii, whence there ' is a large outturn of lump ore bringing in 
a handsome profit to the operators, so that there can be no lack of the 
comparatively small capital required to provide the plant that would 
be needed for the treatment of smalls and dust. It is very pleasing to 
the miner to export the very best ore and make a sovereign a ton profit 
on it with a comparatively small amount , of trouble, and to neglect 
all ore that will not bring in profits at the same rate ; but it is not 
gratifying to India, to see a portion of her mineral capital wasted. 
Similarly, of the ore that is obtained in lump size, only that of the 
very best quality is considered worth noticing

wishes to get a reputation for supplying ore only of a certain quality, 
although it could also work lower grade ore at a profit if it liked. To do 
this such firms throw away all ore of lower grade than their standard,
