never much at a time, and always remembering to work 
upon it firft with the bruifer, for fear any gritty particles 
may find their way upon the polilher. If the bruifer be 
apt to flick, and do not Hide fmoothly upon the. pitch, the 
furface of either tool may be occafionally brufhed over 
with the foap and water, but it muft be remembered that 
the wet brufh muft be but lightly rubbed upon the foap. 
In the beginning of this procefs Iktle.effedt is pro- 
duced, and the metal does not feem to polifh faft, in fome 
meafure owing to its taking the polifh in the middle, and 
perhaps becaufe neither that nor the bruifer move evenly 
upon the polifher : but a little perfeverance will bring the 
whole into a good temper of working ; and, when the 
pitch, is well defended by the coating of the putty, the 
procefs will advance apace, and the former acquiring pof- 
fibly fome little warmth, the metal moves more agreea- 
bly over it, with an uniform and regular fruftion. All this 
while the metal muft have no more preflure than that 
which it derives from its- own weight and that of the 
handle ; and the polifher muft never be fuffered to grow 
dry, but, as often as it has any tendency to do, fo, the edges 
of it muft be moiftened with the hair-pencil; and .now 
and then, even when frefh putty is not laid on, the fur- 
face of the polifher fhould be touched with the, brufh to
