is the case, but little polish after the first need be used.
Much depends upon the last finish of the surface of the plate,
and as a fine impression is desired in the same ratio,
the operator must exercise care and skill in this operation.
Some buff the smaller plates on the hands, by resting them on
the fingers in such a manner that the buff cannot touch them;
some by holding the edges with thumb and little finger,
with the remaining fingers under, or on the back; and others buff
on the holder. When this last method is adopted, it requires
the greatest caution to prevent the dust from getting on the buff.
The holder should be wiped clean.

The plate frequently slips off or around, and the buff comes
in contact with the bed of the holder. When, however, the operator
is so unfortunate as to meet with this mishap, the utmost care
must be observed in thoroughly cleaning the buff cover before
further buffing. In this last buffing it may be continued as before,
except without the application of polish powder to the last buff.
Examine the surface occasionally, and buff more lightly towards
the close of the operation, using at last the mere weight of the buff.
This last buffing should occupy as long a time as the first.

The point to be aimed at is, the production of a surface of such exquisite
polish as to be itself invisible, like the surface of a mirror.
The secret of producing pictures discernible in any light, lies in this:
the more dark, deep and mirror-like the surface of the plate, the more
nearly do we approach to perfection.

In all cases, very light and long continued buffing is productive
of the greater success, since by that means a more perfect polish
