The  results  claimed  are  a  largely  augmented  yield  and  a  much 
purer  product.  Conversation  with  a  number  of  turpentine  gatherers, 
however,  indicated  that  they  would  not  accept  any  system  which 
involves  the  use  of  cups,  since  the  first  cost  is  not  the  only  outlay, 
but  the  additional  expense  occasioned  by  wear  and  tear  almost  pro- 
hibits their  use. 
Dr.  Charles  Mohr,  of  Mobile,  Ala.,  special  agent  for  the  U.  S. 
Division  of  Forestry,  has  been  inclined  to  look  with  favor  on  this 
process,  although  he  confesses  his  inability  to  decide  after  only  a

season's  observation  of  its  working.  The  following  is  from  a 
communication  from  Dr.  Mohr  concerning  it : 
"  Schuler  admits  that  the  first  cost  for  providing  the  cups,  putting  them  up 
and  removing  them  the  second  season,  raises  the  expense  of  working  a  crop  of 
10,000  cups  for  two  seasons  to  $460,  against  $190  for  cutting  10,000  boxes, 
expended  under  the  old  system  in  working  one  crop  for  two  seasons  ;  all  other 
expenses  connected  with  the  work  being  considered  equal.  On  the  other  hand, 
Schuler  claims  that  the  difference  is  vastly  overbalanced  by  the  increased  yield 
of  crude  turpentine  obtained  by  his  cup  methods,  amounting  for  one  crop
