way  that  you  have  hitherto  tiled  the  common  ooze,  there 
not  being  the  leaft  variation  required  with  refpecft  to  any 
of  the  previous  management  before  the  Ikins  or  hides 
are  fitted  for  the  ooze.  Every  thing  that  relates  to 
cleaning,  liming,  flefhing,  &c.  is  to  be  conducted  pre- 
cifely  as  in  the  old  or  common  method  of  tanning;  and 
the  goods  are  to  be  worked  in  the  handlers  for  the  requi- 
lite  time,  and  then  laid  away  in  the  vatts,  with  layers 
and  heading  of  bark,  juft  as  you  now  praclilc ; and  when

different  ufes  for  which  it  is  intended.  You  are  always 
to  obferve,  however,  that  the  ooze  is  to  be  turned  from 
one  letch  on  another  before  it  is  ufed,  other  wife  it  will 
be  apt  to  blacken  the  leather. 
xiv.  What  has  been  hitherto  faid  relates  only  to  butts 
and  calf-fkins:  as  to  foal-leather,  which  is  prepared  for 
the  ooze  by  fteeping  it  in  fome  four  liquor,  in  order  to 
open  its  pores,  and  raife  it  (according  to  the  tanner’s 
phrafe)  the  new  method  requires  a different  practice 
from  the  old  one.
