SECTION  ON  COMMERCIAL  INTERESTS. 
H.  P.  Hynson,  Chairman.  H.  D.  Knisei^y,  Secretary. 
The  first  session  of  the  Section  on  Commercial  Interests  was  called 
to  order  by  the  chairman,  Mr.  H.  P.  Hynson,  on  the  evening  of 
September  4,  1906. 
After  extending  the  usual  greeting  to  the  members  present,  the 
chairman  called  on  the  delegates  from  the  several  State  pharma- 
ceutical associations  to  outline  the  several  methods,  proposed  or 
adopted,  for  improving  the  commercial  condition  of  the  retail  drug 
trade  in  their  own  State. 
In  connection  with  these  reports  the  possible  effect  of  the  intro- 
duction of  parcel  post  was  discussed  at  some  length.  Among  other 
subjects  of  immediate  interest,  the  direct  responsibility  of  retail 
druggists  for  vending  adulterated  or  impure  drugs  and  chemicals 
was  also  given  more  than  usual  consideration. 
The  discussion  on  co-operative  buying  was  one  of  unusual  interest 
in  that  it  evidenced  how  widely  varied  are  the  opinions  that  can  be 
formed  on  any  one  subject.  Among  the  contributions  on  this  sub- 
ject, the  following  papers  represent  probably  the  extremes. 
Advantages  of  Co-operative  Buying. 
By  W.  C.  Anderson. 
The  author  believes  that  co-operative  buying  clubs  of  from  10  to 
300  members  are  born  of  necessity  rather  than  choice.  He  also 
believes  that  the  objects  that  are  sought  are  worthy  and  are  of 
benefit  to  all,  even  the  smallest  dealer,  chief  among  these  advan- 
tages is  the  possibility  of  securing  fresh  stock  in  small  quantities,  at 
a  minimum  price.
